Hello,

I have one stand alone Hyper-V host - hvserver01 (Hyper-V Server 2012 R2) and 3 VM's running on it. One Virtual machine is our company's additional Domain controller.
I'm planning to install an additional hyper-v host - hvserver02 (Hyper-V Server 2012 R2) as well.

I have the following task to perform: I need to move domain controller virtual machine from hvserver01 to hvserver02.

So, for this operation which tool do i need - move, export/import or something else... ? or it will be necessary to install a new DC and then demote the old one.. ?

Is there a some special requirements when moving DC from one virtual host to another.. ?

And also, - MS Hyper-V Server 2012 R2 is installed on both Hyper-V hosts.

Do you have some advices ?

Thanks in advance,

I have been running into an interesting but an alarming issue with virtual switches. I have recently built a 4 node Server 2012 Hyper-V failover cluster. I have built numerous 2008R2 and 2012 Hyper-V clusters before, so I am pretty familiar with the process. I have rebuilt my VMM due to software problems, and on this new cluster, I have configured the virtual switches with nic teaming on 2 of the virtual switches.

I have 4 clusters being managed by this VMM.. and this newly built cluster keeps losing all of the VMM virtual switch configurations, meaning if I go to properties on the problem host and click on virtual switches, its blank. Refresh host cluster flags all virtual machines in this cluster as "Unsupported Configuration," making the vm unmanageable via VMM. 

Information (26844)
Virtual switch (Virtual Switch Name) is not highly available because the switch is not available in host (One of the Hyper-V Hosts).

Recommended Action

All virtual servers on that host still has connectivity, as all virtual switch configs are normal when looking at it with Hyper-V Manager or Failover Cluster Manager..

The workaround is to evacuate the host using Failover Cluster Manager and reboot the host. Then refresh the host. Then refresh the VM's. I cannot consider this a 'workaround' as I cannot be rebooting my hyper-V hosts every week.. and migrating virtual servers constantly just for this reason. (DPM backups have a FIT with csv's if it tries to backup a vm on a same csv as another vm thats being migrated.)

I have been wrestling with this problem for a few weeks now. The cluster has been slicked and completely rebuilt.. Still same problems. Has ANYONE else out there seen this issue? Does ANYONE out there suggest a way to go about further troubleshooting this issue?

Hi All,

I have HP DL380 servers with Broadcom network adapters. I have successfully created the team and selectDynamic as the load balancing mode. This team has selected for the virtual switch. My VMs couldn't communicate to each other. sometimes it communicates with the physical host and sometimes not.

For the troubleshooting purpose i have selected a single adapter as the stand by mode. After that sometimes VM can communicate among each other and sometimes not.

I have found the below article for the same issue.

http://www.aidanfinn.com/?p=16876

i would like to know is there any solution for the issue. Also would like to know is this a bug from Microsoft or the Broadcom?

Regards,

Windows 2012 R2 VM with SQL 2014 on Hyper-v 2012 core is throwing SQL errors during VSS replica.  I have ran a test failover and the recovery point seems fine.  It almost looks like no database changes have occurred and the VSS engine is aborting the thread inappropriately.  If this is not an actual error is there any way to suppress these messages?

I'm attempting to build a Windows7 Ultimate 64-bit VM within one of my Hyper-V hosts to add to my cluster. My result when attempting to start the VM is a black screen stating "Starting Windows" and goes no farther. I have several 2012R2 VM's running without issue within these hosts on my cluster.

Steps taken:

1 - Verified my .ISO file is valid and not corrupted.

2 - Tried a verified second .ISO image

3 - Made sure of my RAM and HDD settings.

4 - The VM will hit the ISO and act like its going to load successfully but hangs on "Starting Windows."

5 - Deleted VM and started over (numerous times.)

One thing that I have noticed that is different on this WIndows7 VM is under the Firmware settings as it's set to "No boot entries." where my other vm's a set to boot from a file.

I have a limited knowledge base on Hyper-V and leaning to my fellow IT colleagues for professional advice. I appreciate any help you can provide. Thank you. What can you suggest?

Hi,

I have a few questions about NIC teaming in Hyper-V:

- Is teaming and bonding the same thing?

- Can I add the same virtual adapter to a VM twice and then team this? I would guess I'd need to team them first to get one effective NIC I set an IP on. Or is the correct configuration to use different physical NICs? (I currently have 4 uplinks on the same physical NIC).

- If I do the above, is there a requirement for teaming @ the NIC level?

Thanks!!!

Hi,

I have a single R710 with hyper-v 2012 installed on it. 

I am managing hyper v 2012 from a windows 8 host. 

I have installed server 2012 VM.

I have 2 networks connected to the physical R710.

In virtual switch manager I have configured 2 switches. One of these switches is shared with the management OS hyper v. 

Second switch just points to the second physical NIC.

My problem is this:

When i connect the VM to the first switch it works fine. 

When i connect the VM to the second V switch (second physical NIC). The VM gets a DHCP IP address and is able to ping everything behind the FW. It just doesn't ping outside. i.e. google.com or 8.8.8.8

There are no firewall rules blocking traffic. 

Can anyone tell me what I am doing wrong?

Thanks in advance.

All,

I would like to share my (free!) solution for installing software on a Hyper-V guest, when that installer checks for usb support.

My problem was that I tried to install a HP printer and scan driver in a Windows XP guest, running on Windows 8 Hyper-V. The installation failed with a message that no USB hardware and drivers were found and setup could not continue...
Duhhhh, I am trying to install it as a network printer/scanner, you HP morons!

After searching the web, I found various solutions. One of them was installing the Guest OS under VMWare Workstation, install the HP printer software (since VMWare workstation has USB support) and then migrate the VMWare guest to Hyper-V. I thought this was way too much work!

Then I stumbled on the KernelPro usb-over-ethernet solution. I downloaded the free client and installed it on the Windows XP guest under Hyper-V. I did not connect to any usb-over-ethernet server, as I do not have one. However, having the usb-over-ethernet client running, made the HP installer believe the Hyper-V guest had full USB support and happily installed the software.

Here you can find the free download for the KernelPro usb-over-ethernet client:http://www.usb-over-ethernet.com/download.html.

Kind regards,

Erik Cheizoo

Hi.

I have a Supermicro VDI server with dual Nvidia GRID K2 cards running Windows Server 2012 V2 with Windows 8.1 virtual machines. The drivers on the server are current. Some of my local RDP terminals have 30" monitors @ 2560x1600 and some have 27" Ultra Wide screens @ 2560x1080. I have set the RemoteFX resolution in the Hyper-V manager to be 2560x1600 max for all VMs and yet I cannot get the RDP session to display the ultra wide format. The 16:9 aspect ratio displays fine. The 30" monitors display 2560 x 1600. But the 21:9 will not go full screen. The VMs in those sessions are stuck at 2048x1080. I tried setting the graphics slider in the RDP options to 2560x1080 (that option exists on the slider) but the result stays at 2048x1080. Same if I set it to full screen. If I RDP to the same VM on a host with a 30" screen it shows full resolution. The 27" screens show a 3" black bar on either side. I've tried setting the RemoteFX to dual screen. No change. It will not output to that aspect ratio.

I have seen that this is an ongoing Hyper-V issue on other forums. The only solutions I've seen proposed revolve around using VMWare or Citrix. That is not an option at this point.

If anyone has any ideas to share I would love to hear them. Is there a fix aside from buying a bunch of different monitors ?

Thanks

Howdy!

I've recently faced a problem where attaching an old VHDX file with Windows 8 RTM on it WITH opening this VHDX in Explorer somehow corrupted this disk.

What I did:

1. Imported an already used virtual machine into Hyper-V Manager using the Import Virtual Machine command in Hyper-V Manager.

2. Added an old VHDX disk with a Windows 8 RTM setup on it.

3. Opened this VDHX in Windows Explorer.

4. Ejected this VHDX from Windows Explorer.

Issues:
1. When starting the imported VM with this VHDX, I get the "No boot device error".

2. When opening this VHDX in Windows Explorer, I get:

"The disk image isn’t initialized, contains partitions that aren’t recognizable, or contains volumes that haven’t been assigned drive letters. Please use the disk management snap-in to make sure that the disk, partitions, and volumes are in a usable state."

Attaching the disk using diskmgmt.msc does not allow to initialize it. All commands except for Detach VHD are grayed out.

This VHDX contains important data! Is it possible to recover it?

So to get started I'll give a bit of background on the Infrastructure we are currently working with.

We have:

2 x Hyper-V Hosts (Currently 2 for testing migrations, this will increase once we have a working platform)
2 x File Servers acting as storage nodes for VHD Storage
1 x Physical DC

The Hyper-V Hosts both have Server 2012 R2 Datacentre installed, the rest have Server 2012 R2 Standard installed and configured.

We currently have some VM's sitting on one host and I am in the process of simulations to make sure live migration is working between the two HV Hosts (This is a non-clustered setup), Everything is on the domain and i've been using a domain admin account to administer these servers for these simulations.

We plan on having VHD's stored on FS01 and FS02, basically our primary host is going to have all primary servers on and then those vhd's will be stored on FS01 and then all secondary/redundant servers are going to be on the second host and vhd's stored on FS02 - Simple enough?

I can perform Data migrations between both FS01 and FS02 using the Hyper-V Management tool on both hosts without any issues. The issue I am currently encountering is when I perform a migration of the "Virtual Machine Only". Now, this simulation works when the data for the VM is stored on either of the hosts using UNC pathway, no hiccups at all, I receive the below error when ever the data is stored on either FS01 or FS02 using again, UNC pathway (These VM's power on and work perfectly otherwise while hosted on FS01/02).

Error:


I've researched this quite a lot and have gone through countless solutions other people are having.
http://social.technet.microsoft.com/Forums/windowsserver/en-US/5780d041-4036-404e-9f33-8abe025bfe2b/hyperv-failed-to-create-external-configuration-store-general-access-denied-error-ox80070005?forum=winserverhyperv (Which took me to the below link)
http://support2.microsoft.com/kb/2249906 (This solution didn't work, in fact i couldn't even get CMD to run the command)

Now, with THIS SOLUTION that I attempted I worked with adding all the hosts and FS01 (because nothing is on FS02 at the moment) in an attempt to get the VM Migration only working between hosts and still receive the same error.

As a testing option, I Moved the Data for the VM back to one of the hosts using UNC pathway and then performed a live migration to the other host no problems, then performed a data migration back to FS01 and that also worked. I don't particularly want to do this with production VM's as I have at least 6 x 780GB vhd's that need to be moved and this would move them more than once, obviously not ideal.

If someone is able to help me out, or at least point me in the right direction, that would be awesome!

Hello,

We have a Windows Server 2008 R2 Service Pack 1 with Hyper-V role, it seems that every time we reboot the server, and after CTRL-ALT-DELETE and login, it takes longer and longer to show the desktop. This is on the Windows Server 2008 R2 Service Pack 1 Hyper-v physical host. Any reason why? I thought maybe applying this updatehttp://support.microsoft.com/kb/982210 but it does not show for service pack 1. Can anyone help why is it slow, we have 4 hyper-v vms? Thank you

Hi. I am creating a lab environment with 2 networks containing several vm’s running windows server 2012. I am connecting the networks using RRAS on a separate machine.

Each vm has 2 virtual switches; one is a private connection type  and the other is a public connection type. When both network connections are enabled on the vm’s, I cannot ping across the 2 netoworks. The only way I can ping across the 2 networks is if I disable the public network connection on the vm’s. Is there a way to have both the private and public network connections enabled and still be able to ping across the networks ? Thanks in advance.

Hi and thanks for reading. How do I remove or delete a vswitch from a team (not from a vm) or do I have to delete the Nic team?

I seem to only be able to find powershell cmds to delete or remove from a VMachine.

If you can help please can you post the actual cmd to delete\remove any of the vswitch as shown in the image.

Any help much appreciated.

Hi!

I'm running Windows Hyper-V Server 2012 R2. In one beautiful day the server stopped responding partly. I mean all quest machines are still running and I can see event viewer and ping it, but server shares or remote desktop or Hyper-V manager are not accessible any more.

In system log I see following errors:

• 10010 - The server {8BC3F05E-D86B-11D0-A075-00C04FB68820} did not register with DCOM within the required timeout. - after every 30 seconds, in the end this is the only error!

• 7011 - A timeout (30000 milliseconds) was reached while waiting for a transaction response from the Winmgmt service. - everything starts with this error.

After I restart the server it works for some hours or maybe a day and the problems start again.

Any ideas what can be wrong or how to troubleshoot?

Thanks in advance!
