Hyper-V 2012 R2 & Windows 8.1 VMs performance metrics using WMI query

Hi,
I used the following query to fetch the Disk utilization for Hyper-V VMs (non v2 hosts) using its host credential "select ReadBytesPersec,WriteBytesPersec,ReadCount,WriteCount from Win32_PerfRawData_StorageStats_HyperVVirtualStorageDevice" but
for the V2 (Windows 8.1 & Windows 2012 R2) this query is not working this is throwing Invalid class using the namespace "root\cimv2".
Please let me know the exact WMI class for the Disk utilization for V2 hosts VMs.
Regards
Raamesh Keerthi N J

Hi,
In my lab server 2012R2 , I run this command :
get-cimclass | Where-Object { $_.cimclassname -like "*hypervvirtualstoragedevice" } | fl cimclassname
I got two classes :
Win32_PerfFormattedData_Counters_HyperVVirtualStorageDevice
Win32_PerfRawData_Counters_HyperVVirtualStorageDevice
You can try them

Selecting a boot drive for Hyper-V 2012 server - is a boot drive performance important?

I'm setting up a new Hyper-V 2012 server dedicated to virtualization and I'm trying to determine the best choice for the boot drive.
I have 2x250gb SSD drives i'm considering for storage pools for VM's
I have an old 80GB SATA drive
I'm wondering how important the primary boot drive is in a Win 2012 Hyper-V setup. I can partition one of the SSD's to provide a boot partition, or I can just dedicate the 80GB SATA.
What do you think would be a better choice?
Edit: A more precise question, why not partition the SSD for boot? Is there any benefit for separating the disks for boot vs just the partition?
Thanks,
Deco

Hello,
I hope you are having a great day!
What resources are available to you? If you have hardware RAID, it would be best to configure the SSD drives for RAID 1 (mirrored) and run everything from that. This will provide you fault tolerance in the case of a drive failure.
If hardware RAID is not available to you, then definitely use the 80GB SATA drive as the OS Boot Drive, without a hardware RAID for the OS disks you will have a single point of failure no matter what disks you use. Yes with SATA drive the system will boot
up slower :-( , but that is about the only negative.
This will also enable you to leave the SSD's as RAW un-formatted disks which can then be configured in a Storage Pool with mirroring if you wish and then have the VHD's reside there.
Absolutely, dedicate the SSD's for the placement of the Virtual Machines Config and Vhd/Vhdx Files.
For absolute best performance results use VHDX Fixed disks for maximum performance.
Dynamically expanding VHDX will have a minor almost unnoticeable performance hit (depending on the purpose of the VM) and help ensure that the amount of hard disk space the VHDX file is occupying is kept to a minimum. An example of degradation in performance
would become noticeable if for instance, the VM is being used as a file repository and users are constantly uploading files.
The bottom line is, if you don't have hardware RAID for the OS you always have a single point of failure, so hope for the best and keep great backups.

SCCM 2012 R2 Report using WMI Query

I am trying to find out if I can generate a report to show which users installed what software using a report in SCCM 2012 R2 and a WMI Query.
If not using the reporting within SCCM, then:
1) is it possible to pull such data via a wmi query
2) any suggestions how to do so?
3) Desktop OS is either Windows 7 or 8 or 8.1 Enterprise x64
Thanks,
Dave
David Lakey

You Can Create Query With the Software name but you can Know Which Computer and you can add System Resource as the Last login name
This for Example:-
From monitoring--> Create New Query--> Edit Query Statement --> Show Query Language
past the following:-
select SMS_R_System.NetbiosName,
SMS_G_System_ADD_REMOVE_PROGRAMS.DisplayName from
SMS_R_System inner join SMS_G_System_ADD_REMOVE_PROGRAMS on
SMS_G_System_ADD_REMOVE_PROGRAMS.ResourceId =
SMS_R_System.ResourceId where
SMS_G_System_ADD_REMOVE_PROGRAMS.DisplayName like "%Visio%"
After that in General you can add in Results Tap:-
System Source and the Attribute Will be last Login name

Installing SCVMM 2012 r2 in a VM on Hyper-V 2012 and windows failover cluseter

Hi,
I am planning to configure scvmm 2012 r2 that will be managing 30 hyper-v host servers, please guide me will it be ok if i install and configure both scvmm 2012 r2 and sql server 2012 on same VM running on Hyper-V Failover Cluster ?

Hi,
Like most of the time, there is a lot of possible topology to achieve your design.
Installing VMM and the database in a virtual machine on the same cluster that it manage is a supported scenario.
The first question you have to ask is : What is the availability level i need for my VMM infrastructure ?If
you shutdown the SCVMM instance for patching, you are not able to deploy new VM from template, and not able to create and manage Virtual Networks. It don't affect existing VM or Virtual Networks. Does this break your SLA ?
Most of the time, VMM don't need a guest cluster (unless you are a hosting provider with provisionning portal
available 24/24 7/7).
The main advice i will give you is :
Keep it simple as possible !
Don't build complex infrastructure if you don't need to achieve a very hight level of availability.
Availability, complexity and management cost have a exponential relation.
For large deployment, you can use a dedicated Hyper-V cluster to deploy System Center and infrastructures services (SCVMM, SCOM etc...) But there is nothing wrong in deploying VMM in the same cluster as the VM it manage. The design you have to achieve should
be thinking in terms of availability and serviceability.
I don't think that 30 Hyper-V hosts need a dedicated SQL Guest Cluster.
If you install VMM on one VM and SQL on another, you will not achieve more performances, but your VMM instance
will be less "portable".
Cheer.

Server 2008 R2 with WSUS need to specify location for Feature install for Server 2012 and Windows 8

Having a problem where we need to add .net 3.5, amongst other things, in server 2012 and windows 8.1. We're using WSUS on server 2008 R2, so when I go to add roles or features, I'm not able to as it tries to use Windows Update but it's set to use WSUS.
I'm aware in server 2012 gpo's that you enable the policy 'specify settings for optional component installation and component repair' in Administrative Templates>System, however that setting is not available in Server 2008 R2.
I've downloaded the templates from http://www.microsoft.com/en-us/download/details.aspx?id=36991 but the setting is still not there.
Any suggestions on how to do this/allow feature install with Server 2008 R2?

Hi,
To upgrade the Administrative Templates, please run the downloaded msi file, then copy the needed admx files and adml files to the PolicyDefinitions folder.

Deployment Guide - Branchcache 2012 with Windows 7 clients

Is there a deployment guide for branchcache using Server 2012 and Windows 7 clients? I can find 2 guides, 1 for Branchcache 2008 with Windows 7 and 1 for 2012 with Windows 8. Wondering if I should just follow the 2012 guide for configuring branchcache servers
and 2008 guide for configuring Windows 7 clients including PKI?
Thanks

Hi,
Thanks for your post.
Windows Server 2012 is compatible with Windows 7.
But BranchCache in Windows Server 2012 and Windows 8 provides substantial performance, manageability, scalability, and availability improvements. And there are some group policy only applied to client computers that are running Windows 8 not Windows 7.
So i would suggest you may choose client computers that running Windows 8.

Unable to Install Windows Server 2012 on Windows Server 2008 R2 SP1 Hyper-V

My attempts to install are failing with a message "Windows cannot install required files. The file may be corrupt or missing....Error code: 0x800705070".
I am posting this on the Wondows 2012 Server forum but I have had exactly the same problem as described below with Windows 2008 R2 SP1.
As the title says this is on a Windows Server 2008 R2 SP1 host with all current updates. I have downloaded the ISO file from a Technet subscription file twice, once by direct download and once by the Akamai downloader. The virtual disk is connected with
the default IDE driver. I mounted both installation images as ISOs, located on a file system on the host server. I have tried installs by deleting the VM and recreating both the VM and a new virtual disk, re-using a previously created virtual disk, and
deleting the partitions in a previously created virtual disk, and executing the format command, and then attempting the install.
I have exactly the same problem trying to create a Windows Server 2008 R2 SP1 VM on the same host OS. With those attempts, I downloaded the Technet subscription iso 4 or 5 times, and burned one to a DVD which I attached to the created VM. Same
error message.
The virtual machines and virtual disks I created and used were all located on an RAID5 array, on a builtin Intel RAID controller using Intel Rapid Storage Technology software version 11.2.0.1066. The host Windows Server 2008 R2 SP1 uses this file system
but the OS is installed on a dedicated drive (C).
I had previously created a guest VM with Windows Server 2008 R2 (several months worth of updates ago) without drama.
I have spent hours reading forums and blog articles on this. A common response is to download the iso another time, and/or burn it to a DVD instead of mounting an iso image. Although I didn't do the later yet with 2012 Server, but I have done these
other steps attempting to install Windows 2008 Server SP1. The install process takes a while (not to mention doing multiple downloads). Given this seems to be a common recommended remedy, and indeed based on posts does seem to eliminate the problem is some
cases, why doesn't somebody change the Microsoft installer program so it does a thorough integrity check at the beginning of the install process?

Jeff,
After the exercise of Windows 2012 Server successfully installing (as I described above) I also successfully installed Windows 2008 R2 on Hyper-V. From my standpoint, I have eliminated the problem (which isn't the same as correcting the problem).
The answer to your specific question regarding Hyper-V support is that the motherboard I am using, an Asus P5Q, is not supported by Windows 2008 R2 because it doesn't use ECC memory, and the vendor doesn't say it supports Windows 2008. But I am sure you
know the motherboard vendors often don't test older motherboards with newer software versions. It appears that in specifying ECC memory Microsoft is trying to protect users of Windows Server from hurting themselves, not saying the software won't run.
Having said that, my suspicion in the beginning was, and still is, that it was some variable(s) left in an unknown state in the Hyper-V environment, which was why after trying to install Windows 2008 R2 several times I tried Windows 2012 which resulted in
the same error, and then encountered the same error trying to install Windows 7 on the same Hyper-V installation. The specific Hyper-V Windows 2008 R2 server had run without any operating problems for months before I started having trouble, and although it
had been quite a while since I had created VMs, that process used to work. The hardware didn't change. What changed was applying updates through Microsoft Update, and a few access control rights I changed, and at least I think, I set back to their original
value.
So in short, no, my hardware isn't supported by Windows 2008 Server. Two, your assertion that you are running the same software configuration that I am is very unlikely to be true. There are an extremely large number of things which are different between
your test system and mine, such as which Windows 2008 components are installed, what updates were installed and in what order they were installed, and what other third party software each of us is running, and between AD, and all the features, a large number
of potential differences in ACLs, options, etc. and I don't for a minute think this particular problem was caused by the underlying hardware.
I do appreciate your taking the time to try to help me, and I hope there is one thing you and I could agree on. Microsoft could pretty easily make it much easier to isolate problems. In this day and age reporting hex error codes (as opposed to doing the
table lookup in the error handling proc), and not providing more diagnostic information seems to me to be almost quaint. And in this case Microsoft can dismiss my problems on the grounds it was all on unsupported hardware. Unfortunately, I think they
are missing an opportunity to make their software better, because in my opinion what I encountered there are a set of conditions which will cause installations to fail that aren't going to get corrected.

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

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
Leandro Soares - MCP/MCSA/MCTS

Hello Brian!
The customers doesn't have access using the RDP / ICA. The role machines is web servers.
In the VMs I can find only the following log:
Log Name: System
Source: Microsoft-Windows-Kernel-Power

Event ID: 41
Task Category: (63)

User: SYSTEM
Computer: xxx
Description:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
But on the Host Hyper-V I cannot find any error related to this failure as I described in this thread.

Move VMs from Hyper-V 2008 R1 to Hyper-V 2012 R2

I have a Server with Windows Server 2008 (NOT R2) running with the Hyper-V role installed and 8 VMs.
I want to move them to our new server running Hyper-V 2012 R2.
I tried to copy the original files to the 2012 Server and Import them as described in a similar article on this site (not allowed to post a link) but I get following error message (translated from German):
Error while importing.
The VM-Version of the virtual Maschine xxx could not be updated: unknown error 0x80004005
The VM-Version 1.0 of the virtual Maschine is not supported.
Any suggestons / ideas on how to fix this Problem?

Hi Ralf,
>>I am afraid that there might occur a Problem with a double SID now?
There is no "double SID" if the SID that you mentioned is Virtual Machine SID , because you have created a new VM with new SID .
But if you mean operation system SID (I assume that OS is windows OS) then "double SID" might arise when they are online at the same time (but I think the original VM should be offline after you create that new VM ).

Hyper-V 2012 R2, integration services issue on multiple VMs

Hello,
I came to you because we encounter a technical issue on one of our Hyper-V (2012 R2).
Our backup (Veeam backup in last version) are still failing with error :

After checking integration service states of those VMs on the Hyper-V, we get this result :

The status is OK, but If I retry my backup I have the same error.
So, is there a way to reinstall integration service component without rebooting ?
Many thanks for your help.

On the Windows VMs that are not 2012 R2, insert the Integration media ISO, install it, and reboot.
When all is done, run this:

Hyper-V 2012 VMs freeze on large file transfers

I have a small non-clustered Hyper-V Server setup as follows:
HP ML350p Gen8 Server, 6 core E5-2620 CPU and 32GB Memory running Server 2012 (full GUI) with the Hyper-V role enabled.
The Server has 8 disks, 1 pair of RAID1 15k disks for the Server 2012/Hyper-V OS, and 3 pairs of RAID1 10K disks for 3 VMs (ie each VM has its own pair of RAID 1 disks). The NICs in the Server are 4 x gigabit ports on an internal
331i card and 4 x gigabit on an external 331T card. The Hyper-V Server is not running anything other than the Hyper-V role, the LogMeIn client and Symantec SEP SBE 2013 (with recommended Hyper-V exclusions in place) and
the VMs are a Domain Controller, a SQL Server and a File Server. Currently all VMs have their own single 1GB NIC connection on the 331T card, all VMs have a single IP address and are on the same subnet, no VLANs are used.
I have applied what hot fixes I can from a TechNet article that recommended how to setup Hyper-V.
Initially I had a problem with NIC latency during pings, which we traced to being due to the ML350 Gen8 Server's NICs not liking VMQ enabled. When disabled all looked fine, but we had not yet tried to use the Server in production.
Recently (getting ready to go in to Production use) we have noticed when transferring a 3.5GB ISO of SQL media to a file share on one of the VMs from a desktop PC that this causes the VM to lock up. The file copy will still complete but the screen freezes
when accessed via Hyper-V manager or remotely via LogMeIn and sometimes the LogMeIn remote session is dropped too. If you cancel the file copy the console is immediately responsive again.
Since we built the server a while back, HP had subsequently released an updated NIC driver which we installed and it seems to have fixed the VMQ issue, but with or without VMQ enabled we seem to experience the lockups as soon as we transfer medium to large
size files. The issues were there before and after we upgraded the NIC driver, we were hoping it would address the issue, but it didn't. These servers are very lightly loaded and the problem occurs even on the SQL Server VM with the SQL service disabled
(ie the server has hardly anything running at all and the console freezes with a single user performing a single file copy).
We have 3 VMs on the Server, 2 are running Server 2012 and seem to be more affected, the VM running Server 2008 R2 seems less affected. VM to VM transfers seem to be working better (ie slows down slightly but no lock ups), it is only during external network
transfers. Also the faster the transfer speed is, the worse the issue becomes. If the file is copied to a share on the Hyper-V Host the issue does not occur, only transfers to the VMs.
Does anyone have any idea what might be the issue here? I saw a hotfix for 2008 for a similar issue but can't seem to find anything for Server 2012.

I think we have tried almost every combination of disabling Large Send Offload, TCP offload, IP SEC Offloading, VMQ and Receive Side Scaling possible - in the various places there are - although I will be quite honest - as there are 3 places to do this
for each Server (the related physical and virtual NICs on the HV Server, and also the NIC in the VM) it is possible we may have missed an iteration...
During our testing we have noticed that the symptoms of the problem gets worse the higher the transfer speed is. For example if you transfer to the VM from a desktop with a 100Mbs NIC, there will be subtle lag and a transfer speed of say 10 or so KBs ,
if you use a device with a 1Gbs NIC, you on average achieve 50-70 KBs transfer speeds and the higher the number, the worse the GUI / Server locks up (although the transfer completes just fine).
We also tried throttling the bandwidth via the 2012 GUI - to see if that helped, but none of the changes we made seemed to work, and we did not have time to try the powershell way of doing this.
We did replace one of the VM's NIC with a legacy one as part of our testing today, and now data transfers to the VM from a PC with a 1Gbs NIC run slower at around 30-35 KBs and the are no noticeable GUI freezes, although during the large transfer
it looks like 1 in every 30-40 packets is dropped in a continual ping that runs during the transfer period.
We have done a lot of cable replacing today (out of diligence) but there seems to be no noticeable issue. We also tried and older NC380T dual port NIC we had available and used the standard driver Windows offered instead of an HP one, but the problem
was identical no matter which NIC we used.

Hyper-V 2012 High Availability using Windows Server 2012 File Server Storage

Hi Guys,
Need your expertise regarding hyper-v high availability. We setup 2 hyper-v 2012 host in our infra for our domain consolidation project. Unfortunately, we don't have hardware storage that is said to be a requirement that we can use to create a failover cluster
for hyper-v host to implement HA. Here's the setup:
Host1

Hyper-V role, Failover Cluster Manager and File and Storage Services installed
Host2

I'm able to configure the new feature about Shared Nothing Live Migration - i'm able to move VM's back and fort between my hosts without storage. But this is planned and proactive approach. My concern is to have my hyper-v host to become highly available in
the event of system failure. If my host1 dies, the VMs should go/move to host2 and vice versa. In setting this up, i believe i need to enable the failover clustering between my hyper-v hosts which i already did but upon validation, it says "No disks
were found on which to perform cluster validation tests." Is it possible to cluster it using just a regular windows file server? I've read about SMB 3.0 and i've configured it as well i'm able to save VMs on my file server, but i don't think that my hyper-v
hosts are already highly available.
Any feedback and suggestions or recommendation is highly appreciated. Thanks in advance!

Your shared storage is a single point of failure with this scenario so I would not consider the whole setup as a production configuration... Also setup is both slow (all I/O is travelling down the wire to storage server, running VMs from DAS is ages faster)
and expensive (third server + extra Windows license). I would think twice about what you do and either deploy a built-in VM replication technologies (Hyper-V Replica) and apps built-in clustering features that does not require shared storage (SQL Server and
Database Mirroring for example, BTW what workload do you run?) or use some third-party software creating fault tolerant shared storage from DAS or investing into physical shared storage hardware (HA one of course).
Hi VR38DETT,
Thanks for responding. The hosts will cater a domain controller (on each host), Web filtering software (Websense), Anti-Virus (McAfee ePO), WSUS and an Auditserver as of the moment. Is the Hyper-V Replica somewhat give "high availability" to VMs or Hyper-V
hosts? Also, is the cluster required in order to implement it? Haven't tried that but worth a try.

DPM2012 R2 protecting Hyper-V 2012 R2 Cluster VMs, some appear offline in DPM

Hello,
We have 2 separate Hyper-V 2012 R2 Clusters using iSCSI SAN CSVs as storage.For these I have set up 2 PSGs for VM backups using checkpoints (As new in DPM 2012R2/Hyper.V 2012 R2)
90% of the VM backups work in online mode but some shows as Offline when running the DPMGuide to add a VM to a PSG.The server OS versions differs between WS2003 R2 SP2/WS2008 SP2 / WS2008 R2 SP1 / WS 2012.
Windows Server Backup is installed on all VMs and vssadmin list writers shows no errors.How can I elaborate and solve this issue?

Hi Elton,
Thanks for your answer, My comments in bold indent below.
The Backup (Volume Snapshot) Integration Service is disabled or not installed.
Installed and enabled on all those VMs
A virtual machine has one or more dynamic disks.
I know this is a supposed issue, however all other VMs with both Dynamic / Fixed disk VMs
does work.And among these failing we have both dynamic / Fixed disks as well.
A virtual machine has one or more volumes that are based on non-NTFS file systems.
All Vms has NTFS
In a cluster configuration, the virtual machine Cluster Resource Group is offline.
The Cluster Resource Group is online
A virtual machine is not in a running state.
All are running
A Shadow Storage assignment of a volume inside the virtual machine is explicitly set to a different volume other than itself.
Interesting, how do I check this in the VM itself ?
Thx /Tony

Virtual Machine Generation 2 Boot Issue!!! (Windows Repair Bootloop! ) Hyper-V 2012 R2

Hello people, I'm having the following with the GEN 2 in Hyper-V 2012 R2.
Issue: After bouncing my GEN2 Hyper-V VM I get this.
Then I get the Windows Repair and nothing happens after this point!
Does someone have experience this issue ?
The bad thing with it is as it's production there's no checkpoints and I cannot recover it!
Note: this doesn't happens with GEN1 VM's.
Any help will be really appreciated

Hi, thanks for the quick response. Now the images are appearing... oh well...
Quite familiar to me this one. I have a couple of, or more, remedies;
1: increase the available memory to at least 4096 - just whilst installing you can alter it later.
2: make sure the enhanced session switches (both in Server and User) in the hyper-v manager are not enabled - you can re-enable them later
3: Disable "Enable Secure Boot" in the VM settings - Firmware - you can enable it after the install
4: make sure Heartbeat is enabled in the VM's settings - Integration Services
5: Last, but not least, make sure the Smart Paging File Location is the same as the VM's location. Eg: VM: <D:\VMS\Machines> Smart Paging Location: <D:\VMS\Machines>
One or more of these has "always" worked for me in the past. I don't offer any warranty with these "solutions", but by disabling or enabling the various options I have nearly always been able to get the VM started.
Is the ISO you are utilizing good? One client of mine assured me he had never touched the ISO saved in that 'special place'. A quick peer at the files inside the ISO revealed that he had been at the files and changed a minor file and then changed
it back to what he thought it had said...
Cheers
