All vm's in hyper-v 2012 core cannot initialize

Hi,
All vm's in hyper-v 2012 core cannot initialize.
there is ram and space in drive. Tried to run windows update and restarted hyper-V.
any suggestions?
Thanks

So on your other host, 10.21.0.150 (?), right-click on the folder 'virtualmachines' and select 'Properties'. Go to the 'Sharing' tab and enable sharing. You will need to specify the domain admin, in your case, to have full permissions to the share.
Note that I wouldn't really recommend your approach from a permissions point of view - rather, I'd create a separate account within AD for this, grant that user full permissions to the folder, and then provide these credentials from your Hyper-V host.
I'm not sure which OS you're using for hosting your 'virtualmachines' folder, but http://technet.microsoft.com/en-us/library/cc770406.aspx should provide additional information
for actually configuring your shares.
Further, I'd use a little more descriptive name than just 'New Virtual Machine' in order to help keep things more organized as your environment grows.

How to check the RAID or HDD config in Hyper v 2012 core

I have hyper v 2012 / hyperv 2008 core running in rack server. I wanted to verify whether the server is in RAID or not. How do i check that?

Hi Sathishkumar M,
I think that the best solution is to check from the RAID controller BIOS.
Anyway try with the command DiskRAID

any suggestions ?

Since we're talking about 2012R2, I'm not a fan of the syntax after checking technet. Let's rework the order a bit and try this command:
New-VHD -Path D:\Virtual Machines\Movies.vhdx -SizeBytes 800GB -Dynamic

Cannot install GUI to Hyper-V 2012 R2 server core

Hi everyone,
I have followed this article to convert a server core install to have a GUI installed:
http://andersonpatricio.ca/enabling-and-disabling-the-graphical-interface-in-hyper-v-server-core/
When I run the powershell command:

I get the following error:

I have checked if there is a folder called Winsxs under c:\sources\windows and it is not there. Looks like the install.win file does not have it.
There is no bloody way of installing a GUI onto HypervCore.
If anyone has had any success with this, I would like to hear from you.
Many Thanks

I think you might be right.
I even tried a large install.wim image and tried the following command after mounting the image onto a mount point:

There is a lot of confusion between Windows 2012 R2 Hyper-v Core and just the Hyper-V R2 hypercore free edition.
Those commands are going to work for the first option. The free version cannot have a GUI.
The only way I can fix this by removing this hypervisor and and installing Windows 2012 r2 with hyperv role, restore the configs and the VMs.
Thanks for all your help.

Hyper-v 2012 R2 server core recommendations for single server setup

Hi All,
Next weekend I will be installing a brand new Dell 720 server for a client of mine.
I would like to hear some recommendations on how to install this hypervisor.
Let me state that I have had some experience with virtualization technology in the past with VMWARE ESXi.
This is a small client with under 10 users but I have learned that with the 2012 product offering you cannot get Small Business Server any more. I know Microsoft has Windows server 2012 Essentials but you would have to have Exchange server in the cloud which
my client does not want. He wants to run his Exchange server in house.
Also he needs Remote Desktop Services (Terminal Server) because his accounting application requires it.
He has an existing Windows 2003 domain controller that eventually has to be decommissioned because it is too old and slow.
So I thought I install Hyper-v 2012 R2 core on the new server and then create 2 VMs:
1) Windows 2012 STD to run as a secondary domain controller.
2) Windows 2012 STD member server with Exchange server 2013 and Remote Desktop Services role.
My questions here are these:
1) Do I install the Hypervisor in workgroup or domain mode?
2) When I am finished with the old server do I transfer the AD FSMO roles onto the VM that is acting as a domain controller?
The new server has 2 CPUs. How does Microsoft licensing go here? I know that Windows 2012 STD gives me 2 instances with the same product key on the same server for 1 CPU. What happens if you have 2?
Can someone give me some insight on how to go about this? I remember that I found this easier with VMWARE Esxi.
Now with Hyper-V I need to also get a management workstation with Windows 8 professional on it to manage the Hyper-V core server.
Thanks and regards
Alfred

In regard to the VM's:
1.) DC: If you're going to be installing a second domain controller that is 2012 R2, you might consider reading this guide first.
http://msmvps.com/blogs/mweber/archive/2012/07/30/upgrading-an-active-directory-domain-from-windows-server-2003-or-windows-server-2003-r2-to-windows-server-2012.aspx
2.) Exchange: Here's the guide for installing Exchange 2013 on Server 2012. I don't believe R2 is supported yet for 2013.
http://social.technet.microsoft.com/wiki/contents/articles/14506.how-to-install-exchange-2013-on-windows-server-2012.aspx
3.) Host: You'd install the host in domain mode....but that point may be moot after you read #5.
4.) FSMO: I would verify the health of the 2012 DC before moving the roles. All too often I'll see a new DC get stood up, sysvol won't be published, the engineer will be in a rush to move the FSMO's, and things get a little sideways. Ultimately
you don't HAVE to move the FSMO's until you are ready to decommission the 2003 box.
5.) Licensing: No licensing rights convey with Hyper-V Core, so this may not be best for your scenario. See the queen mother of all Hyper-V licensing posts here -
http://www.aidanfinn.com/?p=13090
For what it's worth, plenty of SMB's are going to Office 365 to avoid the on-prem administration headache, but your client wants what your client wants. Sorry if this isn't the news you wanted but I hope it helps.

Upgrade Windows Hyper-v 2012 R1 core to windows Hyper-v 2012 R2 Core

Hi all,
is it possible to upgrade stand alone hyper-v 2012 R1 core server to hyper-v 2012 R2 core server?could anyone guide me the process of upgrading? I really appreciate your help. Thank u so much in advance.

Hi D.sree charan,
"A clean upgrade is safer, if you do not mind exporting and re-importing the VMs, or moving them all to another host, before the upgrade. On the other hand, with the upgrade cycle now faster than before, in-place upgrade makes sense as
a way of keeping pace with little pain."
For details please refer to following link :

Enabling GUI on Hyper-V 2012 R2 Core

I have seen several articles about enabling Minimal Server Interface (GUI) on 2012 core. Such as ...
http://www.admin-magazine.com/Articles/Windows-Server-2012-Tricks
Trick #6
None of these work for me. Is this because I installed from a 2012 R2 Hyper-v ISO instead of a 2012 R2 Install disk and selected 'Core' install?
Also, is there a licensing difference between 2012 R2 Hyper-v and 2012 R2 Core install with Hyper-v and GUI enabled?
Thanks.

Hi,

How do I turn off Hyper-V 2012 server sleep mode?

Just installed Hyper-V 2012 server on a HP ML360 G8. Also installed Corefig 1.1.1. It seems after about 10 minutes if idle time the monitor goes black and the unit goes into sleep or hibernation. I have used powercfg to set it to the High Performance
power scheme and set screensaver to none in Corefig.
When the monitor goes black, if I move the mouse the sconfig screen, corefig, etc windows do not show until I run the mouse over them. Even then the windows do not 'repaint' until I run the mouse over the whole window or make some kind of key stroke in each
window.
Worried what this will do to my VMs once I start building them and would like to see the screen at all times. This is the first 2012 box and I have never had this issue with any of the Core 2008 products.
Thanks

Hi,
“I can't locate the GUI you show, it's Hyper-V 2012 Server,so i can't edit the settings.
Sems like it may be the monitor itself is going to sleep”
The other possible is you don’t have the administrator rights, or your server has got the Power Management, after you configuration the power option, the GPO refresh then
the old configuration be covered. Please refer the following article to confirm that:

Hyper-V 2012 R2 roles, access denied, failed to connect to service, AzMan....

Hi All,
I have followed dozens of tutorials to set up roles for Hyper-V, but I keep coming up short. I have no problem managing the five domain-joined 2012 R2 Core Hyper-V servers we have remotely from my Windows 8.1 PC, but I have a lab box I would like to grant
specific permissions to some Help Desk users on.
The key tutorial I have followed is from John Howard (http://blogs.technet.com/b/jhoward/archive/2008/04/01/part-4-domain-joined-environment-hyper-v-remote-management-you-do-not-have-the-requested-permission-to-complete-this-task-contact-the-administrator-of-the-authorization-policy-for-the-computer-computername.aspx),
but it still does not allow a non-admin account to use Hyper-V Manager remotely. Without his tutorial, I get access denied with my "TestUser" account. After following his steps, Hyper-V Manager appears to connect to the server, but says "The
Virtual Machine Management service is not available." Even using his HVRemote with the /show flag, everything shows as PASSED.
Digging deeper, I see dozens of failed audit Event Viewer logs saying "TestUser" is requesting READ to Service Control Manager. That sent me searching, and I found
http://arnoutboer.nl/weblog/?p=300 and http://msdn.microsoft.com/en-us/library/windows/desktop/aa374928(v=vs.85).aspx.
After granting "AU" (Authenticated Users) every permission resembling "read", Hyper-V Manager now shows "There are no virtual machines to show" (or something along those lines); even though I know there are about 30 VMs on this
host. I try to create a new VM (out of curiosity, and now that those options actually appear), and I get permission denied immediately after the create VM wizard pops up.
Why is this such a convoluted process? I would appreciate any help creating Roles for Hyper-V 2012.
Thank you in advance!

Hi Eric (cool name BTW!)
Putting them in Hyper-V Administrators is definitely not an option.
I absolutely believe Microsoft would do something to push you into buying their software; just as we had to purchase Windows 8.1 Pro to remotely manage our 2012 R2 servers. However, as far as I am seeing, AzMan is still in 2012 R2. Whether it works or not
is another story, but AzMan.msc is still there and I can run it on any of our 2012 R2 GUI installs.
Actually just found this:
http://technet.microsoft.com/en-us/library/dn303411.aspx. According to that, it has not yet been removed, but it has been deprecated. From what I am seeing, the Hyper-V portion of it is definitely broken.
I will look into the remote endpoints solution you mentioned. Thank you for the suggestion. I just recently took the plunge into learning C++, so maybe a Hyper-V manager of sorts will be an app to
attempt to write, haha.

0x80070569 Error When Creating Second Virtual server in Hyper-v 2012

I get this error when I try to create a second VM from Hyper-v Manager on windows 8 / server 2012 / server 2008 R2.
Hyper-v is running on a new install of server 2012 core.
I was able to create the first VM (server 2012 with a GUI) and is running fine.
I have tried adding the local administrator account to the logon as a batch job and doing a gpupdate /force with not luck.
Both the server 2012 core and the server 2012 VM are joined to the same domain. I am logged into server 2012 and server 2008 R2 as the domain administrator.
Any ideas would help!

Hi,
Error Message: The user has not been granted the requested logon type at this computer, this problem typically occurs when the user does not have the permissions to log on locally on the computer.
By default, members of the Users group have the ability to log on locally, but an administrator can deny the right to specific user or group accounts. An explicitly denied right always overrides an allowed right.
This can be caused by either of the following:
Neither the user account nor any of the groups it belongs to has been granted the Allow log on locally user right.
The user account or one or more of the groups it is a member of has been listed in the Deny log on locally user right.
Ensure that the user, or a group the user belongs to has the right to log on locally. Ensure that the user, and all groups that the user belongs to, are not denied the right to log on locally.
Also, have you tied to restart to restart the Hyper-V host server? Restart it and check the result.
You may also try to create VM using PowerShell command:

Hyper-v 2012 r2 slow throughputs on network / live migrations

Hi, maybe someone can point me in the right direction, I have 10 servers 5 Dell r210s and 5 Dell R320's, I have basically converted these servers to standalone hyper-v 2012 servers, so there is no clustering on any at the moment.
Each server is configured with 2 1Gb nics teamed via a virtual switch, now when I copt files between server 1 and 2 for example I see 100MBs throughput, but if I copy a file to server 3 at the same time the file copy load splits the 100MBs throughput between
the 2 copy processes. I was under the impression if I copied 2 files to 2 totally different servers the load would basically be split across the 2 nics effectively giving me 2Gbs throughput but this does not seem to be the case. I have played around with tcpip
large send offloads, jumbo packets, disabled vmq on the cards, they are broadcoms. :-( but it doesn't really seem to make a difference with all of these settings.
The other issue is If I live migrate a 12Gb vm machine running only 2gb ram, effectively just an o/s it takes between 15 to 20 minutes to migrate, I have played around with the advanced settings, smb, compression, tcpip not real game changers, BUT if I shut
town the vm and migrate it, it takes, just under 3 and a half minutes to move across.
I am really stumped here, I am busy in a test phase of hyper-v but cant find any definitive documents relating to this stuff.

Hi Mark,
The servers (hyper-v 2012 r2) are all basically configured with ssvmm2012R2 where they all have teamed 1Gb pNics, into a virtual switch, then there are vNics for the Vmcloud, live migration etc. The physical network is 2 Netgear Gs724T switches which
are interlinked and each servers 1st nic is plugged into the switch1 and the second nic is plugged into the switch2.See Below Image) The hyper-v port is set to independent Hyper-v load balancing.
The R320 servers are running raid 5 sas drives, the R210s have 1Tb drives mirrored. The servers all are using DAS storage, we have not moved to looking at using iscsi and san is out the question at the moment.
I am currently testing between 2x 320s and 2x R210s, I am not copying data to the vm's yets, I am basically testing the transfer between the actual hosts at the moment by copying a 4Gb file manually, After testing the live migrations I decided to test to
see the transfer rates between the servers first, I have been playing around with the offload settings and rss, what I don't understand is yesterday, the copy between the servers was running up to 228Mbs ie (using both nics) when copying
the file between the servers, and then a few hours later it only was copying at 50/60Mbs, but its now back at 113Mbs seemingly to be only using one nic.
I was under the impression if you copy a file between 2 servers the nicks could use the 2gb bandwidth, but after reading many posts they say only one nic, so how did the copies get up to 2Gb yesterday. Then again if you copy files between 3 servers, then
each copy would use one nic, basically giving you 2Gbs, but this is again not being seen.

RDS - Issue using Windows 10 build 9926 as Virtual Desktop Infrastructure on Hyper-V 2012 R2

We currently have a production Windows 8.1 as a VDI/RDS on Hyper-V 2012 R2. On testing the last build of Windows 10 (98??) we had no issues deploying this in same RDS as pooled desktops.
The latest build 9926, although correctly sysprep-ed (either by removing AppX modern apps that have been updated, or not connecting the template to the internet), the build is only ever partially successful. Some VMs build others do not, and the ones that
build cannot be managed via RDS/Server Manager, functions such as logging a user off with server manager, result in an error. (WTS API failed)
Build Error on connection Broker - Microsoft-Windows-TerminalServices-SessionBroker
VM host [HOSTSERVER05] failed to execute VM Provisioning operation [Task: To perform post processing actions at VMHostAgent:] for virtual machine [VDI-W10-57] in pool [VDI_Advanced_Te], Error: [Error code: 0x88130221.]
Any guidance on how to troubleshoot this would be greatly appreciated, although I suspect something regarding the auto-deployment/unattend and management systems though RDS no longer works with the latest Windows 10 build.
Already posted this in the
Windows Insider Program site, but was asked to re-post here. Thanks

OK, I've carried out some more testing on the client site and have been able to move a couple of existing VMs from their 2008 R2 Hyper-V server to the new 2012 R2 server.
Both VMs are Windows 7 SP1 with the RDP 8.0 update installed and I can connect to them from a Thin Client running RDP 7.1 and a laptop running RDP 8.0.
When I add the RemoteFX vGPU to them both I can still connect from both devices but, as suggested, when connecting from the laptop with RDP 8.0 I don't get the vGPU performance (but the vGPU is still shown in the device manager).
It all looks good at the moment but I'm still concerned as to why I was unable to connect to the first VM I moved over (it was complaining about a error in the License network communication or similar).
I'll keep testing and post anything else that might be useful.
Cheers for now

SLES 10 (SP3) on Hyper-V 2012 R2

I do realize that is unsupported (only SP4 supposedly is)
But I have SLES 10 (SP3) image that got converted from vSphere
Once I can boot the IDE disk (by editing menu.lst to /hda1 & uninstall Vmware Tools, I would need to get network connectivity, so logical step would be to use Intergration Services 2.1 (one that supports SLES 10 SP3)
But it is a no go. On make install during load of vmbus the whole VM just hangs & dies
http://imageshack.com/a/img545/7339/16u1.jpg
The initrd never even gets created as it dies & reset is the only option
If I rem-out vmbus start in Makefile then I can get new kernel installed, but restulting kernel will panic on VM boot
Anybody has any clever idea how to get it working (if at all possible)
Seb

Getting this to work is going to be difficult. The older LIS 2.1 does not work with Hyper-V 2012 and 2012 R2 due to changes in Hyper-V itself. But you could probably get SLES 10 SP3 with LIS 2.1 working if you went back to the older Hyper-V
2008 R2.
You are correct that the LIS 3.4 package is created only for the Red Hat (and CentOS) distros. It will not work with SLES releases.
We've gotten occasional requests to get SLES 10 working on Hyper-V 2012 and 2012 R2, and we're in conversations with SUSE about creating a combination that works. But we don't have anything to announce about a timeline. When/if we get something
working, it will most likely be SLES 10 SP4, since that's the most up-to-date version from the SLES 10 series.

VMs on Hyper-V 2012 R2 are shutting down automatically

Hello Guys!
I'm having a huge problem in my Hyper-V 2012 R2 environment. Yesterday, 9 of 40 VMs were shutdown automatically, and so, caused a downtime problem to my customers in the business hours.
I checked in the Event Viewer (Application / System / Microsoft - Windows - Hyper) of the Host and VM but I couldn't locate any log related to this unexpected shutdown.
It occurred twice yesterday, the first in the morning and the second in the afternoon. I'm afraid that this issue can happen again. I've tried to locate some logs to identify this problem, but no luck here.
My question: Is there any other place where it can help me in this troubleshooting to find the root cause?
Obs: All the VMs are licensed / activated.
Obs2: The VMs are Win 2008 R2 Std

Virtual Machine Manager to manage Hyper-V 2012 R2 Servers

Hi,
I am trying to create an environment wherein I have few Hyper-V 2012 R2 hosts, Windows Server 2012 hosts, and Windows Server 2008 hosts. All are registered to a AD server.
On Windows Server 2012 host, I have created a virtual machine on which System Center Virtual Machine Manager 2012 SP1 is running. This Virtual Machine Manager is perfectly able to manage Windows Server 2008 hosts.
However when tried to add Windows Server 2012 hosts and Hyper-V 2012 R2 hosts, it gives the following error:
Error (2916)
VMM is unable to complete the request. The connection to the agent windows2012.test.com was lost.

Recommended Action
Ensure that the WS-Management service and the agent are installed and running and that a firewall is not blocking HTTPS traffic.
This problem can also be caused by WMI service crash. Ensure that KB 982293 (http://support.microsoft.com/kb/982293) is installed on the machine if it is running Windows Server 2008 R2.
If the error persists, reboot windows2012.test.com and then try the operation again.
Checked:
> WS-Management service is running
> VMM agent got installed
Questions:
1. Whether System Center 2012 SP1 - Virtual Machine Manager is compatible to manage Hyper-V Sever 2012 and Windows 2012 R2 Server.
2. What is the latest version of VMM to manage Hyper-V Sever 2012 and Windows 2012 R2 Server.

Hello,
I have installed VMM 2012 R2, this is also not allowing me to add and manage Server 2012 R2 hosts. However it is perfectly able to manage Server 2008 host.
It gives following error when tried to add Server 2012 R2 hosts:

This problem can also be caused by WMI service crash. Ensure that KB 982293 (http://support.microsoft.com/kb/982293) is installed on the machine if it is running Windows Server 2008 R2.
If the error persists, reboot windows2012.test.com and then try the operation again.
Any suggestions please?
