Im using Hyper-V on a Windows Server 2012 R2 host. I have two Hyper-V guests: One is a domain controller and another is for a program that needs (almost) all the power.
The host itself has 64GB of RAM, it has Hyper-Threading disabled (the program doesnt perform better with HT enabled, this has been checked out personally) and two processors Xeon E5 2650 v3 (which would mean there are a total of 20 REAL cores).
What is the best way to configure NUMA for the guest for best performance?

I just purchased a new powerful server and placed Windows Hyper-V Server (free version) on it (we do not have System Center).
We use already prebuilt images for student labs (consists of two servers that work together for an enterprise application).
One guest image has AD loaded with its own domain on the other is a client server. We have an automated system that copies the images and then imports then and fires them up.
The problem is they all have the same hostname and it even looks like they get duplicate ip addresses on the Private or Internal switch (only the external virtual switch receives dhcp, I am not sure how the other internal/private switches obtain their ip info). So if we place 3 students on the new server (6 VMs total [3 DCs and 3 clients]), The first two VMs appear fine but attempting to login to anyother DC results in the error: "The Local Security Authority cannot be contacted", I can only guess it getting confused on which is the real DC.
The host has 3 Internal Only switches and 1 External switch for internet access.
Is there a way to isolate each student's environment? I am guessing System Center can help but I am looking for other possible solutions.
Thank You, Joe
I have created system images of my desktop computers using windows 7 back up. Can I 'restore' this backup image to a virtual machine?
How would I do this????
Hey all,
Here's the details:
Site A:
Two node Hyper-v Cluster with 3 guests sending replicas to site B. We'll call the guests siteaguest1, siteaguest2, and siteaguest3. Replica's being sent over port 80. No certs involved.
Site B:
Single Hyper-v host with 1 guest sending replicas to site A. We'll call the guest sitebguest1. Replica's being sent over port 80. No certs involved.
Yesterday morning I got into the office and found siteaguest1 and sitebguest1 replication was behind and failing when I attempted to resume. siteaguest2 and siteguest3 were both replicating normally. Event logs for each failing guest look the same. Every minute I see these two events:
Source: Hyper-V-VMMS
Event ID: 32022
Hyper-V could not replicate changes for virtual machine 'siteaguest1': The connection with the server was terminated abnormally (0x00002EFE).
Source: Hyper-V-VMMS
Event ID: 32315
Hyper-V failed to replicate changes for virtual machine 'siteaguest1' Hyper-V will retry replication after 1 minute(s).
For fun, I disabled replica and then enabled it again and reseeded and I get the same result.
Any ideas as to what might be causing my replicas to fail?
Thanks in advance for your help.
I have extensive experience with VMware, but wanted to setup Hyper-V home lab and learn it. I have a desktop with 8-core AMD processor and 32GB RAM, with 400GB SSD, so I intent to install two Hyper-V VM inside VMware workstation, with 4vCPU, and 12GB, I will also have one Win2008 R2 (1vCPU, 4GB) as DC, and another windows 2012 R2 (to install System Center 2012, I have the CD key). I have dedicated NAS for shared storage. I have the following question.
1). Is System Center the Microsoft solution similar to VMware vCenter 5.5? Can I do shared storage? Live migration (My Hyper-V is free bare-bone installation), how about HA, FT?
2). VMware has the vSphere client, presumably Hyper-V manager (installed on windows 8.1 or Winserver 2012 R2) is Microsoft's answer to that, my understanding is even though I use bare-bone Hyper-V, my function is not limited in anyway compare to type-2 Hyper-V installed inside Windows 2012 server, am I right?
3). Microsoft obviously pus their new OS very hard, so using Hyper-V 2012 R2, can I use Windows XP, Windows server 2012 ? I strongly suspect Microsoft would intentionally limit the scope to protect their OS business.
thanks a lot for your answer.
I installed two Hyper-V bare-metal hosts, a Windows 8.1 Pro machine, one windows 2008 R2 domain controller , all installed inside VMware workstation 11 and bridged to my home LAN, the two Hyper-v hosts and the Windows 8.1 Pro machine, I enabled [1] Virtualization Intel VT-x/EPT and AMD-V/RVI. [2] Virtualize CPU performance counters {VM workstation 11 --> VM -->settings -->hardware--->processor--->virtualization engine}, the two Hyper-V hosts are managed remotely from the Windows 8.1 Pro machine using Hyper-V manager. On my home LAN, I have QNAP NAS and setup iSCSi storage, I easily add the iSCsi storage to the Windows 8.1 Pro machine, but two things buffling
1). How come I could not initiate iSCSi connection directly from the two Hyper-V hosts (I could be wrong here)? or can I initiate connection from two hosts using the remote Hyper-v manager? [I conceptually treat Hyper-V barebone as esxi server, and Hyper-v manager as vSphere client]
2). I added iSCSi to the Win8.1 Pro machine, after formatting, it's treated as local HDD, but I can't add this to the Hyper-V hosts? So far, I must install any VM onto the local HDD of the Hyper-v hosts, both only 20GB, that kinda stinks.
3). How can I add these two Hyper-V hosts to a small cluster? Compare to VMware, Hyper-V is less intuitive, IMHO.
Due to licensing fee, I deploy Hyper-V through bare-metal installation without any Windows 2012 server, but almost every book, video, chat detailing configuration, Hyper-V is usually inside Windows Server 2012 R2. :-(
Thanks!
Hi,
I've had a Hyper-V running Windows Server 2008 for about two years. Today I did a Save on the VM in the Hyper-V Manager and then restarted my computer. When computer restarted I went to Start this VM and got the following error:
[Window Title]
Virtual Machine Connection
[Main Instruction]
The application encountered an error while attempting to change the state of 'WindowsServer2008'.
[Content]
'WindowsServer2008' failed to restore.
Microsoft Video Monitor (Instance ID BA8735EF-E3A9-4F1B-BADD-DBF3A5909915): Failed to restore with Error 'Catastrophic failure'.
[Expanded Information]
'WindowsServer2008' failed to restore. (Virtual machine ID 07307F40-CA38-4780-A62B-CD873410948D)
'WindowsServer2008' Microsoft Video Monitor (Instance ID BA8735EF-E3A9-4F1B-BADD-DBF3A5909915): Failed to restore with Error 'Catastrophic failure' (0x8000FFFF). (Virtual machine ID 07307F40-CA38-4780-A62B-CD873410948D)
===============
The Event Viewer had no additional error information and just repeated the above messages. I did not change any monitor or drivers on my system. I started up a different VM on my system that runs Win 8.1 and that came up with no problem.
What can I try to fix this?

Hello!!!
Last week i instaled the HyperV server in my lab..
But when i go to menu Hyper-v Settings, the menu Replication Configuration is Hidden...
What's Happen?
Can i active the menu?
Hello.
at first excuse me for my bad English, it's not my native language.
I 'm a novice with hyper v and i need help to virtualize my personal home server.
i have 2 systems: a laptop with windows 8.1 pro (client) and a PC with windows server 2012 R2 Hyper-v enabled. (diffrent workgroups)
[laptop ip: 192.168.10.1] - [PC ip: 192.168.10.2]
1)how assign static ip to each vm?
2)Is it possible to automatically create virtual machines from template and set static ip automatically? (can be done with DHCP?? it is important when an VM created it's IP must be static, and when vm deleted ip back to pool[completely automatic])
3)how create a user group that have an limited right (shutdown,reset) [not admin] to control vm from console [just for controling vm not any other work]? please explain it.
4)when i try to connect vm console from my laptop (with hyper-v virtual machine connection) it say error loading vm->you dont have premission... Contact the administrator of the authorization policy.
5) Suppose we have 3 client that want connect to their VM. so client 1 must see just VM1 and not to be able see another vm in the list for connect. What should be done ?
6)how set login password for client?
If a person answers the questions step by step with the images , has been a great help to beginners.
thank you.
Running Hyper-V on windows 8.1 Pro.
The guest state is not updating when doing shutdown, restarting, starting.
When looking in Hyper-v Manager it just says Running in state column.
And the VM guest console window is just writeing standard Ctrl-Alt-Delete instead of what is actualy going on.
Any fix to this?
Having created a new, additional .vhdx drive for a VM, how do I bring it online? Windows Explorer doesn't show it. Device Manager sees it but its status is "offline".
This is on Win2012 Server R2.

Hi,
Ok this is a bit strange. we have a failover cluster with 2 Nodes, both running 2008 I am trying to increase the amount of memory on a particular VM from 6144 to 12288. When I boot the VM back up after changing the memory amount I get an error telling me there is insufficient space, setting the memory back to 6144 and it boots. There is more than enough space on the cluster volume (SAN) and the VM VHDs themselves are fine with more than enough free space.
I have tried removing the VM from the cluster then deleting it and recreating it, attached to the original VHDs and get the same issue.
Any help greatly appreciated.
Regards,
Duncan
Hi
12 node 2012 R2 Hyper-v in Failover cluster configuration. I have an irritating issue where every now and then, when a VM is rebooted from its own OS, the Failover cluster manager will log an error 1069 which says "Cluster resource 'Virtual Machine vmname' of type 'Virtual Machine' in clustered role 'vmname' failed.
This happens every few weeks and isn't a big issue. I've got no cluster stability issues - no issues with clustered disks, hosts or anything. My cluster is as stable as anyone's out there. Apart from when it randomly logs this error when a VM is rebooted.
The VM isn't being backup up when it happens. There are no network issues. Disks all fine. Hosts all fine.
Anyone have an idea why this happens. It's driving me nuts.
Hi Everyone,
I am looking to get some feed back from the real world on what management software is being most widely used by Hyper-V users to manage their Hyper-V virtual datacenters. If you could please let me know from the following options it would be great. The goal is to create a plug-in/console for the software that is used by most Hyper-V deployments.
Please respond to the thread with your replies.

Thanks!

I have i5 proc, asus motherboard and enabled "Intel Virtualization" and "Execute Disable Bit" as in How to enable hardware virtualization on Asus motherboard, but I see no "Intel VT-d" settings to disable it). With this configuration all works great with VM ware workstation(including hypervisor inside hypervisor scenario).
Now I have installed Hyper-V inside Indows 8.1. This one works. After that i have installed Win10 server tech preview 2(build 10074) and enable hypervisor rolse there, there I can't run any virtual machine with message: The Virtual Machine Service failed to start the virtual machine 'X" because one of the Hyper-V components is not runnig.
In the message log I see :
Error: "The HV Host Service service terminated with the following error:
A device attached to the system is not functioning."
Warning: "Hypervisor SPT Resizing policy failed to initialize."
Error: 'Hypervisor Eventlog for global system events could not be created!"
Error" The VM and host networking components failed to negotiate protocol version '6.0'"
"The driver \Driver\vmbusr failed to load for the device ROOT\VMBus\0000."
"Hypervisor launch failed; Second Level Address Translation is required to launch the hypervisor."
What is going wrong? The same scenarion onWin 10 with hyperV role inside vmware workstation works well.
