Hyperv-V vs Not-Hyper-V

Hello Community
    When you have a WS2012 R2 Server and you want to create a
Sharepoint 2013 Server farm there are 2 things you can do:
    1- You can use 3 physical servers and create your Sharepoint 2013
Server farm using those 3 servers ie:
     Physical Server 1 - DC, DNS (server)
     Physical Server 2 - Sharepoint 2013 Server (server)
     Physical Server 3 - SQL Server (server)
    or
    2- You can install Hyper-V on the WS2012 R2 and create your Sharepoint 2013
Server farm using 3 virtual machines ie:
     Virtual machine #1 - DC, DNS (server)
     Virtual machine #2 - Sharepoint 2013 Server (server)
     Virtual machine #3 - SQL Server (Server)
    The question is why would you chose to create the Sharepoint Server farm
to consist of the 3 virtual machines instead of choosing the server farm to consist
of the 3 physical servers?
    Thank you

Hi,
As per your scenarios the second option benefits of virtualization are obvious first thing is money virtualization can bring you so much more for your money secondly Hardware Independence and VM portability
It allows you to easily migrate a VM to any place you like: you can back it up and restore on another server, you can put it on your flash drive and run it on your home lab or workstation
Mware High Availability or VMHA is an option that allows you to restore VMs from a failed server to
another so that you’ll get it back running at no time.
And this is just the top of the iceberg! Virtual machines have got much more great features that the traditional physical server-based infrastructure lacks. But in order to make maximum use of that great new functionality brought by virtualization you should
use the right tools for monitoring, managing and, of course, for data protection. Sincevirtual
machines differ markedly from physical servers

Unplanned failover in a Hyper-V cluster vs unplanned failover in an ordinary (not Hyper-V) cluster

Hello!
Please excuse me if you think my question is silly, but before deploying something in a production environment I'd like to dot the i's and cross the t's.
1) Suppose there's a two node cluster with a Hyper-V role that hosts a number of highly available VM.
If the both cluster nodes are up and running an administrator can initiate a planned failover wich will transfer all VMs
including their system state to another node without downtime.
In case any cluster node goes down unexpectedly the unplanned failover fires up that will transfer all VMs to another node
WITHOUT their system state. As far as I understand this can lead to some data loss.
http://itknowledgeexchange.techtarget.com/itanswers/how-does-live-migration-differ-from-vm-failover/
If, for example, I have an Exchange vm and it would be transfered to the second node during unplanned failover in the Hyper-V cluster I will lose some data by design.
2) Suppose there's a two node cluster with the Exchange clustered installation: in case one node crashes the other takes over without any data loss.
Conclusion: it's more disaster resilient to implement some server role in an "ordinary" cluster that deploy it inside a vm in the Hyper-V cluster.
Is it correct?
Thank you in advance,
Michael

"And if this "anything in memory and any active threads" is so large that can take up to 13m15s to transfer during Live Migration it will be lost."
First, that 13m15s required to live migrate all your VMs is not the time it takes to move individual VMs. By default, Hyper-V is set to move a maximum of 2 VMs at a time. You can change that, but it would be foolish to increase that value if
all you have is a single 1GE network. The other VMs will be queued.
Secondly, you are getting that amount of time confused with what is actually happening. Think of a single VM. Let's even assume that it has so much memory and is so active that it takes 13 minutes to live migrate. (Highly unlikely, even
on a 1 GE NIC). During that 13 minutes the VM takes to live migrate, the VM continues to perform normally. In fact, if something happens in the middle of the LM, causing the LM to fail, absolutely nothing is lost because the VM is still operating
on the original host.
Now let's look at what happens when the host on which that VM is running fails, causing a restart of the VM on another node of the cluster. The VM is doing its work reading and writing to its data files. At that instance in time when the host
fails, the VM may have some unwritten data buffers in memory. Since the host fails, the VM crashes, losing whatever it had in memory at the instant in time. It is not going to lose any 13 minutes of data. In fact, if you have an application
that is processing data at this volume, you most likely have something like SQL running. When the VM goes down, the cluster will automatically restart the VM on another node of the cluster. SQL will automatically replay transaction logs to recover
to the best of its ability.
Is there a possibility of data loss? Yes, a very tiny possibility for a very small amount. Is there a possibility of data corruption? Yes, a very, very tiny possibility, just like with a physical machine.
The amount of time required for a live migration is meaningless when it comes to potential data loss of that VM. The potential data loss is pretty much the same as if you had it running on a physical machine, the machine crashed, and then restarted.
"clustered applicationsDO NOT STOP working during unplanned failover (so there is no recovery time), "
Not exactly true. Let's use SQL as an example again. When SQL is instsalled in a cluster, you install at a minimum one instance, but you can have multiple instances. When the node on which the active instance is running fails, there is
a brief pause in service while the instance starts on the other node. Depending on transactions outstanding, last write, etc., it will take a little bit of time for the SQL instance to be ready to start handling requests on the new node.
Yes, there is a definite difference between restarting the entire VM (just the VM is clustered) and clustering the application. Recovery time is about the biggest issue. As you have noted, restarting a VM, i.e. rebooting it, takes time.
And because it takes a longer period of time, there is a good chance that clients will be unable to access the resource for a period of time, maybe as much as 1-5 minutes depending upon a lot of different factors, whereas with a clustered application, the
clients may be unable to access for up to a minute or so.
However, the amount of data potentially lost is quite dependent upon the application. SQL is designed to recover nicely in either environment, and it is likely not to lose any data. Sequential writing applications will be dependent upon things
like disk cache held in memory - large caches means higher probability of losing data. No disk cache means there is not likely to be any loss of data.

HyperV Virtual NIC not Visable on SCVMM

HI I have installed Hyper V On One of the HP G7 hardware , and SCVMM is on G6 Hardware,

The fact that this does not show up in SCVMM properly makes this an SCVMM issue.
And, SCVMM does not support everything that you can do with Hyper-V.
In this case, SCVMM needs to drive the configuration using Logical Networks and apply this configuration when you host is taken under management. Only then will SCVMM identify and list everything properly.

Windows 2012 R2 Hyper-V event id's 20144 and 15130

Windows 2012 R2 Hyper-V.
After installing the May 2014 MS updates we can no longer start any of the guest VM's. When attempting to start a VM the following is logged in the event logs:
Event id 20144 from Hyper-V-VMMS "Failed to start the virtual machine XYZ' because one of the Hyper-V components is not running" and
Event id 15130 from Hyper-V-VMMS "XYZ' failed to start"
We've looked at http://support.microsoft.com/kb/2761004/en-us and as far as we see the I/O verification option in Driver Verifier is disabled.   We also uninstalled the May
2014 updates that we applied just before the problem started but this did not make a difference.
Help please.

Hi,
I don’t found the similar issue when update, but from the event id, it seems is the incompatible hardware driver, please try to update all your hardware driver and firmware.
Or you can try the following example command to confirm your Hyper-V service is running or not.

Problems with Hyper-V

Hi, i am fairly new to MS virtualisation. So far it has been relatively a great experience bar two problems. One of which was to do with backing up a VM.
i have Window 2008 R2 on I7 CPU with 8GB of memory. Intel Pro/1000 GT NIC and Realtek PCI GBE embedded network interface.
Using export command from hyperv manager was not only exteremly slow. With no progress bar to feed back to the user it was difficult to guess what was going. So i cancel it and then rebooted the system. Unfortunately i lost the whole VM as the files were
corrupted. Fortunately majority of the stuff on it are retrievable. Still i would have been better if this could have been avoided.
With this in mind can i make a few suggestion.
* Back up process should provide some form of feed back to the user. Bearing in mind these are lengthy ops. It should indicate whether it is working correctly or not.
* User should be able to cancel the backup operation at any point without corrupting the VM files. Specially in the case of hyper-v manager command where it requires guest OS to be down.
Hope this helps. 2008 R2 is really a great O/S.

Hi Farjad
I apologise to fall in on another subject but I have searched everywhere for an solution and still I cannot find a solution? Maybe you can help?
I am running server 2012 Hyper-V and I have 2 hosts with each hosting 4 virtual servers, I have no cluster, each host runs their own virtual server and stored locally. Everything is running 100% except one virtual machine that has started with the following
problem recently: Every Friday at the same time the virtual server switches off, I have gone through all log files and event logs and most of the time I get unexpected error? what I have noticed that in the Hyper-V console status bar it appears
as a status "backing up" then it shuts down. I have removed "Volume shadow copy" from both the virtual server and the host on the specific drive where the VM is stored and this is the first Friday it did not Shutdown? I am not sure
if the problem has been resolved but still I am in the dark as to why the status says backing up? what is it thats backs up? and why will the server shut down?
Any Idea?

Hp 550 upgrade of memory and cpu with possible unconventional tweaks. not ideal, but no other choice

HI guys, I hope you can help or at least give a point in the right direction.I'm a freelance photographer using much of the Adobe CS6 creative suite. After a disaster of a week I came home to find that the mother board on my editing workstation somehow is fried. I have no idea what happened though i wouldn't put it past my roommates carelessness.
I'm desperate. I need to finish my current job before I am able to afford to buy a replacement. So I am forced to rely on stopgap measures, out of desperation to finish my project, which are less than ideal, but so far are faring better than I'd hoped.
Im a photographer, Capture One, Adobe Photoshop Lightroom, Adobe Photoshop and Premiere Pro are the go to workhorse applications i need to work. without them i have no income. in order to have this machine run these apps,
the machine i have left is an old hp 550 which was gathering dust in the closet. It was built for 32 bit Win XP and in no way is intended to run the power hog adobe products I use, especially Lightroom.
Unfortunately Lightroom PS, and Premiere are 64 bit programs and LR and Premiere are hyper threaded. so I did research, and with the help of the windows 7 upgrade adviser utility's list of instructions I was able to get windows 7 Pro 64 bit to install and run.
I know this isnt the ideal machine or situation but for a few weeks, i need to make it work.
I really just have 2 simple questions. I had first gone to HP tech support. but they were not helpful. since the Laptop's warranty is long gone, they wouldnt even be polite and basically told me to shove off. Then on another forum, I argued back and forth with a know it all who consistently insisted that there was no way no how this pc could run 64 bit win 7, to which i thought what am i seeing things? its been running fine for 3 months. so i decided to come to you. your forums have been helpful on many occassions.
basically I need this machine to be able to run these programs for the next month or so, until i can purchase a new machine.
essentially, what I would like to know is will the motherboard support an upgrade of the processor? and if it will, what would you suggest as a replacement, considering my needs? The Core 2 duo is the barest minimum of what i can limp along with as photo/video rendering times are excessively slow.
next I was talking to the crucial tech support staff about memory upgrades. and possibly tweaking the bios to force it to run 8 gigs of ram. they said they cold find no version of bios that would make that possible, but that by already forcing it to run 64 bit, that already allowed the pc to utilize the full 4 gigs of ram, which had been impossible in the 32 bit format. He then suggested that i buy 2 4 gig modules such as 4GB DDR2 PC2-5300 Unbuffered NON-ECC 1.8V 512Meg x 64 which can be seen at http://www.crucial.com/usa/en/memory/ct51264ac667 and try installing the full 8 gigs and see what would happened, saying he had a feeling i could get lucky. his logic being that the 64 bit system already opened up the ram limitations and who knows, you cant make an omelette without cracking some egg shells! he seemed very optimistic. So what do you think? does this seem likely to you because i would love it to work. or do you think the guy was a quack? and this whole endeaver is a waste of time and money?
also any other suggestions about how to weather this month long storm that dont involve suggestions of buying new machines would be appreciated!

Here is the Manual:
Service Manual
Unfortunately the maximum configuration is a T5670 processor 1.8 ghz and 4 gigs of DDR2-667 memory which you already have. The CPU includes the 64 bit instruction set so it is not surprising it can run 64 bit Windows 7. My best advice is to save your money for when you can get a real working machine. The only other upgrade likely to help at all is a solid state drive, which you could use in the laptop and then also use in the new computer you are going to buy.

Online Backup of supported Linux VM on Hyper-V 2012 R2 / SC DPM 2012 R2

Hi,
I'm trying to set up a lab environment:
Win 2012 R2 with Hyper-V
running 2 Linux Machines:
Linux2 - CentOS 6.4 with manually installed Linux Integration services 3.4
Linux3 - CentOS 6.4 without LIS (should be already included in CentOS)
Another machine running Win 2012 R2 Server with SC DPM 2012 R2
but both VMs show as "Offline" when trying to back them up via DPM. Tried local Windows Server Backup with the same result.
I am able to backup the VMs "offline" (pausing the VM, taking snapshot, resume VM) but according to MS, SC DPM 2012 R2 should be able to do Online backups for supported Linux VMs (http://blogs.technet.com/b/virtualization/archive/2013/07/24/enabling-linux-support-on-windows-server-2012-r2-hyper-v.aspx)
The only things in the EventLog are these:
A storage device in 'Linux3' loaded but has a different version from the server. Server version 6.0 Client version 4.2 (Virtual machine ID 4F5CDDD8-B855-41CF-83B2-772C1B99090D). The device will work, but this is an unsupported configuration.
This means that technical support will not be provided until this problem is resolved. To fix this problem, upgrade the integration services. To upgrade, connect to the virtual machine and select Insert Integration Services Setup Disk from the Action menu.
Any Ideas ?
Thanks

Hi,
That list would need to come from the Windows hyper-v group, they are responsible with adding the feature to the integration components for various Linux OSes. DPM just backs up whatever the hyper-V writer presents to us, if the guest supports
online, we back it up online, if not hyper-V saves the guest before the VSS snapshot is taken and DPM takes the backup from the saved state.
NEW NOTE ADDED 1-29-14: Windows group just released “Linux Integration Services Version 3.5 for Hyper-V”. The
document mentions that some versions of Red Hat and CentOS are now
supported to do online backup.
Live virtual machine backup support
======================
RHEL/CentOS 6.0-6.3
RHEL/CentOS 5.7-5.8
RHEL/CentOS 5.5-5.6
ADDTL NOTES: If there are open file handles during a live virtual machine backup operation, the backed-up virtual hard disks (VHDs) might have to undergo a file system consistency check (fsck) when restored.
Live backup operations can fail silently if the virtual machine has an attached iSCSI device or a physical disk that is directly attached to a virtual machine (“pass-through disk”).

Problem with VLAN Trunking within RHEL6.6 VM on Hyper-V 2012 R2?

Hello,
I'm wondering if there is a known issue with using a "trunk" mode interface within a RHEL6.6 VM? I found the following article:
https://technet.microsoft.com/en-us/library/dn531026.aspx
Where note 1 reads:
"For this specific RHEL/CentOS release, VLAN tagging may not work when used in conjunction with trunk mode".
I've been fighting with this for the better part of a day and can't figure out what I'm doing wrong. I have a RHEL 6.6 VM with two NICs. The first NIC is a standard access mode NIC - no problems there.
The second NIC has been set up as follows (via PowerShell):
    $a=Get-VmNetworkAdapter -VMName "My VM"
    Set-VMNetworkAdapterVlan -Trunk -VmNetworkAdapter $a[1] -AllowedVlanIdList 101-105 -NativeVlanId 1
Note that the physical switch and switchports are configured to send tagged packets for these VLANs as well.
I then set up a VLAN (eth1.102) based interface in the VM ... and never receive any traffic on it.
What I've observed is that:
A VM on the same physical host using the same virtual switch can communicate with the VM on the tagged VLAN
A pcap of the "eth1" interface (to which eth1.102 is bound) shows traffic for VLANs 101 through 105 arriving ... I just never see the traffic for VLAN 102 forwarded to the eth1.102 interface
An identical network configuration using Ubuntu 14.04.01 LTS works exactly as expected
It's this last point that has me wondering if the problem is with RHEL and not Hyper-V (or the physical/virtual switches involved).
I'm curious if anybody else has seen this behavior or, if RHEL 6.x is working for you, if you're using Intel or Broadcom NICs on the physical Hyper-V host?
Thanks,

This is indeed a known issue with RHEL.   There's a bug open with Red Hat on the issue, and our understanding is that they have a fix in progress that will be part of a RHEL 6.6 update.  You might inquire with Red Hat regarding
their bugzilla #1135347.

Hyper-V - 2 node cluster goes down if one server shutsdown

Hi all,
I built a 2 node cluster with tiered storage and then I started doing some tests:
* Drain one node and all the VMs moved to the other node, perfect
* shutdown the drained node.
The entire cluster crashed!!! The remaining node is trying to re-connect to the iSCSI SAN without success.
* I booted the drained node. And it would not re-connect to the iSCSI SAN either. I had to force the reconnect in the iscsi control panel to make it re connect.
So why would shutting down one node kill the cluster ? Sure it was the node that had the tiered pool online, but even then, isn't failover cluster supposed to put that one back and working on the other node ?
Why did the active node lose the iSCSI connection too ? It had VMs running on it prior to the shutdown of the other node. My DC that was running on that other node is also now un available, can't ping it or anything.
So what did I miss in the configuration of the cluster ? I followed the msdn 2 node hyper-v cluster doc.
I am really worried atm since I had over the past 3 months a ton of issues with hyper-v going from using tiered storage, shutting down nodes, MAC address on the VMs and the hosts,... I thought that after hyper-v 2008, Microsoft had really made some progress
with Hyper-V but I truly regret not going with VMWare again this time around.
That cluster was supposed to go into homologation phase tomorrow at the datacenter but now I am unsure if I ll ever be able to trust it to work.
The SAN is an MD3200i which is reported as Hyper-V ready.
Any hint on where I have gone wrong would be appreciated.
Regards,
Edit: even from the host with powershell I was not able to shutdown the DC and reboot it clean. Said the integration services were not reachable... it is a 2012 R2 servers...
Edit2: One of my VM is gone ! Can't even find the file on the disks either locally on the hosts or on the SAN. WTF!!!

Actually comes across very reasonable. And I think you are right. I tend to compare Hyper-V to vSphere with vCenter included. I have not seen nor used VMM. Also true that Storage Pools and iSCSI is not Hyper-V, but to me it comes as a package just as much
as ESXi 'comes' with it.
As for burning personnal hours and money on books, I have, just as much as I go to conferences when I can and can afford it. And the only thing I would envy you, is the fact you have your colleagues to bounce idea of / lay on if necessary.
As for the few hundred box for the management suite. I believe the stack you speak of would actually cost my current company about 14k$, that is not a few hundred box. That is pretty much the cost of one of the 2 SANs. By 14k$, I mean that
we have 6 servers with 2 sockets each, running a lot of VMs, which means Datacenter licences which list price is 3.6k$. I am not even including the CALs. Or am I mistaken on the licensing ?
If VMWare, I would be going with essentials which, at the same server perimeter, would be 30% less expensive. We don't really need the full blown one at our level.
I am also locked by hardware that was ordered by my predecessor which do not provide the service we need them for. (I blame the vendor on that one, my predecessor was not an infrastructure guy). As for storage, if you are referring to SMB3 and using
a failover cluster to provide the disks to the hyper-v hosts, I agree. I am just not too sure on the technology yet and went more for safety until I can test it thoroughly in the dev environment.
I also hope Microsoft will add an easier way to set the media type on disks as well as allow for more than just SSD and HDD or even allow us to define our own.
I actually fooled the system this time around because SSD are too expensive and too high a failure rate compared to 15kRPM (yes the performance are lovely) at the moment. So I made the 15kRPMs into SSD.
For the remote management issue, i meant that actually, at this time, I have to disable the domain firewall to be able to manage the hyper-v 2012 R2. I tried hvremote, adding all the necessary rules, etc... What I did for 2012 worked perfectly fine and I
had full controls. 2012 R2 does not. I have another thread on this in the forum and I ll come back to it as soon as I can.
I don't really care for the no interface thingy, I enjoy Powershell and scripting fine :) Does a lot of automation for me :) I am used to scripting anyway and it is faster to reproduce steps that way. You do it once, and you got something you can apply with
little changes to everything.
I joined the company in November last year and I got dropped a full stack to upgrade in 6 months while maintaining the current one. Encountering the problem now is better and is, fundamentally, good, though it is time consumming.
By full stack I mean:
* Help the dev re-design the apps so it handles load better. Get out of Windows 2003 and migrate to 2012 and validate all the applications on 2012 as well as improve security.
* Implementing a monitoring system for the infrastructure and the applications.
* Upgrade SQL Server 2005 to, in this case 2012 Standard (no choice and enterprise not in the price range of the company). Converge our current test and prod environments. Optimize all the queries... And naturally validate the applications.
* Upgrade the certificate authorities so they are available on all sites. Haven't scratched that one yet.
* Design a fully site redundant architecture so that if a site goes dark we have no impact. If there is partial failure on one site, no issue either, and so on XD. I wish I had AG :)
* Implement a single windows domain on all the sites, that will be a relief :) Running 4 domains and about 10 different workgroups atm
* Upgrade the firewalls, switches, servers hardware, ... Implement the necessary networks for virtualization and improved security rules... (Don't buy SonicWalls, had a worse headache with them than Hyper-V :) )
* Migrate the users from old domain to new one. Windows 8 does not have the user migration tool anymore :(
* Plan the DR tests and processes :)
* Gotta get Hyper-V replica working as well as backups.
* And naturally make all the documentation so that if I happen to get under a bus, anyone in the company can just follow the documentation in case of an emergency.
And I am sure I am still missing some part of the environment no one knows about at some places :) Found a new network today XD.
As for the mixed VM management, I mean some that are in HA on the cluster and others that don't need and must not failover. Am sure there is a way to configure them in the failover cluster so they don't failover. I just need to spend the 15 minutes looking
into it :)
Since I have had that SAN, I spent about 5 days on the phone with Dell support. That iSCSI issue is not the first one I got :( But in the production environment, that issue has disappeared. So at this time, i have switched working on other issues. And with
the information you provided, I'll be able to know if one of the node of the cluster lose the connectivity which will help avoid this issue in the future.
And it is a very good and interesting challenge. I am just running in way to many issues doing a 10 year old system upgrade :) I was expecting to have an easier time with Microsoft Virtualization than I've had.
Oh and just for the fun, I also had VM disappear, no more file, no nothing, just poof. Have not figured how that happened yet. Had the backup so not much of an issue, but still, it went poof when the original issue happened.
Thanks for the time and the tips :)

SCOM network discovery & port stitching with Cisco UCS & Hyper-V and/or VMware

Before we have our network engineers reconfigure their infrastructure to allow network discovery from SCOM, does anyone know whether or not SCOM will include the virtual switches (Hyper-V or VMware), the UCS fabric interconnects, and the hosted virtual machines in the network vicinity dashboard if you enable network monitoring in SCOM? We're hoping to have monitoring visibility of all network components end-to-end in SCOM, but I've not been able to find any useful information online as to how SCOM network discovery/monitoring handles infrastructure like UCS.

The PF Vnic within UCS Manager has one vlan attached and is tagged native. The Fabric Network Set has a matching network segment with the same vlan ID. I removed the pin group. The port profile according to the SCVMM documentation needs to be set to "Sla only" which removes the options for vlans within the port profile. I've tried adjusting Host Network IO Performance as well with no luck. System Center Virtual Machine Manager 2012R2 still throws the same two errors. One thing to note is we are trying to do this thru SCVMM and not Hyper-V on the host itself.
I opened a TAC case and there is one known bug for
Symptom:
Everytime I assign a Logical Switch to a network adapter or during migration, SCVMM generate an error 25262, "Cannot set a bandwidth setting on the virtual network adapter for the SR-IOV switc
Conditions:
[ From SCVMM, right click VM and assign logical switch to a network adapter.
OR
Migrate a client to a different host.
https://tools.cisco.com/bugsearch/bug/CSCum75054
There is no workaround for the issue currently.
My other issue of
Failed while applying switch port settings 'Ethernet Switch Port VLAN Settings' on switch 'UCS-SCVMM': The request is not supported. (0x80070032).
Unknown error (0x8000) has no fix or information.

Off Host Backup for Hyper-V

Hi<o:p></o:p>
We have a 3 Node Hyper-V Cluster with a Dell 6000
Equalogic SAN connected over 10 GB iSCSI. Actually we use Backup Exec 2012 for
Hyper-V Backup, but I am looking for a Off Host Solution to Backup all Hyper-V
over the San Network. Symantec support Offhost ore ADBO for SQL or Exchange but
not Hyper-V. I am looking for a new good Backup Solution for this Problem. <o:p></o:p>
Thanks for all Tips<o:p></o:p>

What do you mean by "off host"? Do you want to have backup software running directly on top of EQL firmware? Or do you want to avoid proxy servers and have steady stream from EQL to backup storage?

Problem with differencing VHDx in hyper-v 2012 R2

hi friends
in my windows 2012 R2 Datacenter, i deployed a windows server 2012 R2 Datacenter VM ( i selected its hard disk be Dynamically expanding VHDX) & installed OS & then i syspred it & turned it off & removed that VM from hyper-v snap-in.
now i tried to use that as a parent VHDX for Differencing child VHDXs for a new VM.
so i created a new VM & created a differencing VHDx which has that is parent.
the problem is when i turn on the VM, its doesn't boot & i get the following strange error:
i also checked event viewer for all hyper-v nodes in Application & services logs but there is no error & all events describe that VM has started successfully.
what to it can be related?
i have done the same scenario for win 2008 R2 enterprise VMs (VHD hard disk) many times & there was never such problem.
is it isue related to VHDX hard disks?
help please
thanks in advanced

The config looks OK for this Gen 1 VM, except the odd memory configuration.
Can you look up the Hyper-V logs on the host:
particularly hypervisor/operational and VMMS/admin?
You can use Powershell to collect the logs if you like.
Here's a sample script. After running the script to load the function you can run:
Get-HVEventLog -Computername MyHVHost-Days 7

Sam,
i corrected the memory settings & assigned static memory as 1024 MB.
there was two blocks of scripts in that website, i don't which of them i must run.
i verified my event viewer as i had done earlier, i the following are the only events which are are logged in all hyper-v related notes:
hyper-v-hyperVisor node:
Hyper-V successfully created a new partition (partition 3).

Hyper-V host 1Gbps NIC negotiated at 100 Mbps when used for Virtual Switch

Hi all,
Hoping someone can shed some light on this one as I’ve been trying to hunt down a solution for a week now.
Setup
HP ProLiant ML350 G6 with HP NC326i PCIe Dual Port Gigabit Server Adapter network adapters
Windows Server 2008 R2 Core with only the Hyper-V role installed
SBS 2011 installed as guest
Port 1 on Dual port NIC configured a physical port or management of Host only
Port 2 on Dual port NIC configured for use as an External Virtual Switch port for use by guests only
The issue is that the physical port connected to the Hyper-V virtual Switch negotiates with the network switch at 100 Mbps full duplex while the management port negotiates at 1 Gbps full duplex. All clients (brand new HP Z210 workstations) also negotiate
with the switch at 1 Gbps.
During file copies and backups the network port connected to the Virtual Switch does not show any errors and transfers data at close to 100 Mbps. File transfers between individual workstations and workstations and server core again show no errors, but transfers
at 1 Gbps.
One observation is that the physical NIC connected to the Virtual Switch does not negotiate with the switch until the Hyper-V service has started (I’m guessing) the virtual switch.
Also, while staging the server the Hyper-V virtual switch created when the server was connected to a 100 Mbps switch not a 1Gbps switch as it is in production.
Has anyone encountered anything similar and if so how did you get the physical NIC to operate at full capabilities? Any assistance would be greatly appreciated.

Hi,
I purchased one gigabyte switch for home used several days ago, I just performed some copy tests between virtual machines and physical machines(not
Hyper-V host machine)in the same LAN, the average copy speed is 350Mb/s.
Best Regards,
Vincent Hu

OSDComputername HyperV VM

HI All
so I have SCCM 2012R2 and integrated MDT.
I am automating my laptop,desktop and tablet builds using L%assettag% for example and all is working fine.
however when I run tests on my HyperV vms its not working as its spoofing the Desktop and trying to set a computer name which is too long and there for failing. can someone let me know how to either stop it from thinking its a Laptop/desktop or how to set
it to a shorter Serial number.
many thanks
Chris

You can use the IsVirtual variable for one.
Or WMI query Select * From Win32_computersystem where Model='VirtualBox' or Model='VMware Virtual Platform' or Model='Xen' or Model='Virtual Machine'"
Or you can use a VBScript (that's what I do, see below)
Or you can use customsettings.ini like this: ComputerName=#Right("%SERIALNUMBER%",8)#

You are using Hyper-V server and not Hyper-V on Windows Sever.
Hyper-V server is free, but it only includes the Hypervisor and no GUI (Only for managing Hyper-V)
what's your physical machine OS ?
If it's Windows 8 or 8.1 then you can enable the Hyper-V management tools (Programs and features, Turn On/off Windows Features, Hyper-V, Hyper-V management tools). Then open the Hyper-V console and connect to your Hyper-V server.
