To isolate development environment I use hyper-v virtual machine.
Problem is that I nested virtual machine doesn't run.

I was able to install hypervisor on virtual machine using https://msdn.microsoft.com/en-us/virtualization/hyperv_on_windows/user_guide/nesting?f=255&MSPPError=-2147217396, but I have message in eventlog hyperv-worker about unrecoverable error.

PS> See my stackoverflow http://stackoverflow.com/questions/38484893/android-emulator-and-nested-virtualization question.

May be you know how I can fix it?

Hi,

I am facing an issue with Windows Server 2008 R2 Physical machines as well as few Hyper-V role installed machines VM's. The issue is that sometime suddenly the Ethernet stops responding and communication with external machines or other VM's of the same server gets lost, however logging into VM via console we always found that Ethernet is enabled and ping response to loop back address as well as VM IP address within the VM works fine.

If I try to disable and enable virtual nic, it gets stuck and eventually we have to reset server to resolve the issue. After resting, VM works fine. No events related to issue found in event manager (system or application both).

My Physical base servers on which Hyper-V roles installed are Dell Power Edge R410 & R710. Physical Ethernet Cards installed are of Broadcom Corporation (Broadcom BCM5716C NetXtreme II GigE & QLogic BCM5709C Gigabit Ethernet).

Can you please update if this is a known issue and how it can be solved?

I have Windows Server 2012 with Hyper-V role. There is a network team on the server.

When the server starts I receive a error:

I have 1 2008 Server in my network that I am trying to decommission. As a part of that process, I used Microsoft Virtual Machine Converter and turned it into a Hyper-V VM on a 2012 R2 host. 

The machine converted fine (or so I thought), and the old physical server was decommissioned. 

At first it seemed like everything was working fine, but when I install the Hyper-V Integration Services, the VM no longer starts. It get's to the Windows loading screen, and reboots. 

The only reason as to why we are keeping this server at this point, is that it's the Licencing server for our Terminal Server. The fact that this server is now unavailable is causing some of our users to be unable to work from home.

I also don't have the TS license, so I am unable to move this role to a different server. 

Any advice would be greatly appreciated. 

Hello,

I have a Server 2012 R2 host I have recently deployed for a client. Before bringing on-site, I installed the Hyper-V role.

Once on-site, I joined it to the domain in hopes that I could replicate VMs from the old Server 2012 host to the new 2012 R2 server. While configuring replication, I ran into an error stating that the server failed to authenticate using Kerberos. Further research led me to the event log which is throwing errors every 2 minutes like these ones:

Event ID 14050:Failed to register the service principal name 'Hyper-V Replica Service'.

Event ID 14050:Failed to register the service principal name 'Microsoft Virtual System Migration Service'.

Event ID 14050:Failed to register the service principal name 'Microsoft Virtual Console Service'.

I have read several articles about this error without any clear solution. Here are the paths I have followed:

1. Removed from domain, deleted computer object, uninstalled Hyper-V. Joined backed to the domain and reinstalled Hyper-V

2. Ran the code in the following KB: https://support.microsoft.com/en-ca/kb/2761899

3. Tried resetting security settings of the computer object back to defaults as per an article I found

None of these were successful. 

Can someone PLEASE provide a solution to this problem? Thank you.

I am currently running Windows Server 2008 R2 at my work, we have 10 computers connected to the network which up until a few days ago have been working perfectly.

The computers connected to the server will not connect, and what I mean by that is that when the computers turn on they show a purple screen, there is no options for login at all. We have made no changes recently to the server and I have tried everything I could think of to make it work. After restarting one of the computers several times it would bring up the login screen but would take several minutes to login.

A quick fix I tried that worked was unplugging the Ethernet cable from the computer and the login screen came up every time allowing me to type in my login creds then I would connect the cable back up and it would let me login.

Any ideas or suggestions on how to fix this would be appreciative.

This is the error I get:

Hyper-V Volume Shadow Copy Requestor connected to virtual machine 'multipoint2012', but the version does not match the version expected by Hyper-V (Virtual machine ID BF3AD844-337C-4AC2-949A-58638C42559B). Framework version: Negotiated (3.0) - Expected (3.0); Message version: Negotiated (4.0) - Expected (5.0). 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.

I've set up the Integration services setup disk and gone through setup for our system (running x64 on windows server 2012 r2). Half of our network is running fine, the other half is completely down, including all of the VM systems.

I'm pretty n00b to this sort of thing and am hitting a wall right now. 

We are running a Hyper-V-Failover-Cluster with two Nodes. Starting mid-May I see the following error pop up in my event log on both Nodes (Switch-ID is different though)exactly once after a restart:

There may be two incidents linked to the issue, although I am not sure about it.

Cluster-Aware-Updating was installing updates automatically. I remember that CAU was causing us major trouble once this year when an update one Node failed that also killed some Network settings. Major pain in the behind! I got it working again by reinstalling some network card drivers, but I honestly did not understand how. I followed some blog advice on the internet.

We also restructured the network connectivity at one point, deleting the NIC-Team and reconfiguring it. I don't think I made a mistake here, but just to be sure I'll say it.

I don't know what other Information you need, so I just copy-paste some I believe help

Once both Nodes are up and running, the cluster shows no errors and has full connectivity. But immediately after boot I see some weird errors regarding AD/DC/DNS/GPO issues and I believe this could be the underlying issue.

Please advise.

One of my hyper-v host (win 2012) is unresponsive (unable to login locally, RDP, remote computer management).

But all the guest OS inside host are just working fine. I had to reboot the host to resolve this problem and unable to find any error message in the event viewer too. And now it hang for the second time after just a few days I rebooted the host. 

Your response is appreciated. Thanks!

Hi

I've found below piece of Information in some book:

• Hyper-V Management Network - Monitoring and management of Hyper-V host
• Cluster Private Network - Cluster heartbeat and CSV disk
• Live Migration Network - Dedicated to live migration network traffic
• Server VLAN Network (optional) - The administrator can create a single network for all subnet accesses using the VLAN trunk feature or can create a multiple of each network subnet.

Do we need to add these multiple Hyper-V virtual network switches as
cluster networks?

The answer is yes, because when you create a highly available virtual
machine to be run as a cluster resource on your clustered Hyper-V
servers, your Hyper-V cluster needs to have these networks be highly
available and part of your clustered networks.

Is it true?

I use only external virtual switch for Management and Virtual machine access traffic and everything works fine.

I don't use virtual switch for Live migration or Storage traffic.

Kind Regards Tomasz

Hi.

I have a pair of 2012R2 Datacenter Hyper-V hosts which I fully patched as of Thursday 23/06/16 running 2012R2 VMs also fully patched. After installing all the updates all VMs are reporting the integration services require an update.

However using get-vm it reports the services are 6.3.9600.16384 which I believe is the latest version.

Also under the Hyper-V integration service logs on the host it reports it has connected to the VMs and is running the latest version.

If I try and run the integration services installer it gets to installing guest services and then gives error 14101.

Have also updated another pair of servers running 2012R2 Datercenter as a Hyper-V failover cluster and they are showing the same behavior.

Anyone else seeing this?

Regards

James

I have a 2008r2 Hyper-v host with 4 Server 2008r2 guests. I am having problems moving data from disks on the host to the guests. Physically, I have 8 SAS HDDs in 4 RAID 1 mirrors. Each mirror has one of the guests. One of the mirrors also has data that is shared between the guests. If I try to transfer from within a guest from the shared space, I get less than 1Mb/s transfer rates. Going between guests is normal speeds and from shares on the network I get normal speeds. Pushing the data from the host to the guests is normal speeds as well. I'm only having a problem pulling data from within a guest. The server was configured with dual on-board Broadcom NICs. I saw all the problems people were having with those so I bought an Intel I210 NIC and am now using that with the Broadcoms dis-abled in the BIOS, the host OS doesn't even see them anymore.

I have been fighting this for several weeks now and have completely come up short. This system is used for processing data and the scientist that uses does not have access to the host OS.

All,

I have a Hyper V setting installed in our Windows Server 2012 R2 server. 

There is a user who signs into our Hyper V setting windows 7 Operating system using her apple laptop via .rdp. When she types into a word document in Hyper V, she cannot type uppercase letters. When she types in a word document in her apple computer , she can type upper case letters. 

I logged into her same hyper v account and I could type upper case letters using my windows keyboard. 

Can Anyone give me any suggestions to solve this issue? 

Hi,

need to refresh my understanding of apply function in snapshot...

1. Let say I have one snapshot of VM.

Worked on it... Then run Revert to bring the snapshot to point were it was taking.

2. Installed Windows updates. I want to "save" this state in VM forever. I mean that if I will revert the snapshot latest installed Windows Updates will be untouched.

3. Sure after installing updates I can just DELETE checkpoint (it will merge all the changes in snapshot) and then create a new one. So I will achieve what I asked in step 2.

The question: if I will just do APPLY after installing Windows update wouldn't it be enough for "saving" windows updates in VM without the need to DELETE checkpoint?

Thanks.

Hello

I have a two node Hyper-V Cluster built on two Windows 2012R2 hosts. Yesterday after major long power failure (cluster went down due power loss) we have tried to bring it up. On both hosts there is a problem with Microsoft Hyper-V Virutal Machine Bus Provider in Device Manager - it'a marked with yellow triangle with status: 'The driver for this device are not installed. (Code 28). Driver provider is unknown, driver date and version are not available.

This is how it was before:

Device ROOT\VMBUS\0000 was configured.

Driver Name: wvmbusr.inf
Class Guid: {4D36E97D-E325-11CE-BFC1-08002BE10318}
Driver Date: 06/21/2006
Driver Version: 6.3.9600.16384
Driver Provider: Microsoft
Driver Section: VMBus_Device_Root.NT
Driver Rank: 0xFF0000
Matching Device Id: root\VMBus
Outranked Drivers: 
Device Updated: true

And this is how it looks now:

Device ROOT\VMBUS\0000 was configured.

Driver Name: null
Class Guid: {00000000-0000-0000-0000-000000000000}
Driver Date: 
Driver Version: 
Driver Provider: 
Driver Section: 
Driver Rank: 0x0
Matching Device Id: 
Outranked Drivers: 
Device Updated: false

Ive chcecked the drivers location for this device on my another cluster and it seems that on the failed cluster 3 files located in \Windows\system32\drivers went missing: vmbkmclr.sys, vmbusr.sys and winhvr.sys. Ive restored them but device is still not accesible.

How can i fix this problem? 

We have Windows server 2012

we are not getting any such event of VM creation/deletion on our Windows Server 2012.

Any idea anyone, how can we enable such HyperV logs?

Thanks

I just started getting this error and don't what it means:

Event ID: 58

Also getting this error after the above error:

The Hyper-V is been running for 5 months then this error starts.

Please assist

Hello!

I often use non-administratirve user accounts on my test virtual machines and never had any issues connecting to VMs with such accounts. Today, while being signed in to the VM called "Client" as User1 I got a message ~"Updates are ready... install and restart".

After restarting I can't sign in (by clicking "Connect to 'Client'" in the Hyper-V manager and signing in to a VM) as User1:

If I understand it correctly it means that prior to the update a user did not have to be a member of theRemote Desktop Users group in a guest's OS, but after the update he does. Is it by design or something went wrong?

Thank you in advance,

Michael

I'm getting an error on a 2008R2 Hyper V host that has 2 guests. One server will start without any problems, but after this server restarts, the other guest will get stuck in a loop of starting...running...stopping. 

I checked the event viewer and am getting the message 'New Virtual Machine' was reset because an unrecoverable error occurred on a virtual processor that caused a triple fault. If the problem persists, contact Product Support. (Virtual machine ID xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)

This server is a Dell T410.

I've researched this and saw that some people have had this problem with OMSA and BIOS on some Dell servers where the Power Management setting is changed to Maximum Performance and this resolves this particular problem for them. This however has not worked for me.

The only solution for me is to restore the OS vhd from backup from several days prior. This solution is obviously not ideal however.

This problem has happened 2x so far. I'm currently making a restore of the OS vhd for quick recovery next time but don't know what else could be the problem.

There are no reported errors with hardware on this server either.
