SAN Volumes LUN same ID recommended?

Hi everybody,

Is it recommended, that all CSVs have the same LUN ID on each Hyper-V host?

Or is it Ok, if LUN 1 has LUN ID 0 on Cluster host 1 and LUN ID 4 on cluster host 2?

How to enable virtualization in Windows Server 2019 running on Hyper-V 2012 R2 Datacenter.

Hello All,

I’m having trouble activating virtualization features in Hyper-V 2012 Datacenter to virtualize within Windows server 2019.

Can you help me?

How to enable virtualization in Windows Server 2019 running on Hyper-V 2012 R2 Datacenter?
I need to install Docker on the virtual machine with Windows Server 2019 that is running Hyper-V 2012 R2.

I have performed the command below and I do not receive the information that it is not available for activation.

Set-VMProcessor -VMName -ExposeVirtualizationExtensions $true

Thanks for all the help.

Hyper-V Guest Licensing (Host: 2016 STD / Guest: 2012R2 STD)

Hy there!

I apologize in advance for my ignorance with regards to Windows Licensing.

We have a dedicated server with OVH running Windows 2016 Standard, its license is working fine. We have now migrated (via block level disk snapshot) a Windows 2012R2 Standard VM into an Hyper-V guest running on this dedicated server, however, even tough
Windows 2016 Standard should provide 2 virtualization rights, this VM is shown as "not activated".

From what I’ve read we should use AVMA, but that’s only available in the Datacenter Edition AFAIK. Some topics suggest we use the same key used by the Host, but apparently that doesn’t work between distinct Windows Server releases (2016 vs 2012).

I’ve seen some topics suggesting I have to order a "license downgrade" or something. Does that mean I should contact OVH (from whom I bought the license) and request a Windows 2012R2 Standard license for this Hyper-V VM?

This is go into production tomorrow, so please let me know how we can sort this out as soon as possible.

Virtual Machine management service memory leak, server 2016

Hi All,

Wondering if anyone has any ideas what might cause this?  One of my Hyper-v hosts seems to have a problem with the Virtual Machine Management service.  The memory usage for that service just continually climbs, it starts off at a hundred MB but increases
by about 2 GB a day.  I got an alert yesterday that memory usage was high and the service was using 90GB!  There also seems to be other issues, it takes a long time for it to open the hyper-v console, it takes it a long time to start virtual machines,
and sometimes when it reboots it doesn’t autostart all of the machines it is supposed to.

Domain rename and Hyper-V Cluster


I’m planning an Active Directory Domain rename. We have also a cluster with Hyper-V 2016, I’ve tried to search about this operation but somewhere it seems that’s supportted and somewhere they says that’s not supported and I need to rebuild the cluster.

Has anyone some experience with this? what is the correct path?

Thanks for your help

Windows Server 2012 R2 Hyper-V Checkpoints

Hi There,

Recently one of my colleagues created a checkpoint for one of our VMs thats in production. This particular VM hosts the SQL server. Now everytime the back-ups run it creates a new sub-checkpoint for the temporary VM.

The problem is that the actual .vhd has been used more recently than the first checkpoint in this sequence although now one of the checkpoints is currently the disk file that’s in use. My question is that if I delete this checkpoint subtree will it delete
all the checkpoints and associated data since the .vhd has been used more recently than the first checkpoint? Or will it merge the checkpoints with .vhd anyway?

Should I click on the checkpoint and delete the entire subtree? Or just the first checkpoint in the sequence? The server is in production so I would like to avoid data loss if possible, and I know that using checkpoints on a production system is a really
bad idea and addressed it with the person who created it already.

Ideally I would like to just delete this checkpoint tree have it merge with .vhd file and disable the ability to create them in the future.

Let me know if you need more info!

Error Access Denied – Opening VHD at UNCPATHNAME.vhdx and i got error %%2147942432 0x80070020

Error Access Denied - Opening VHD at UNCPATHNAME.vhdx  and i got error %%2147942432 0x80070020

The scenario:

Win2012R2 Hyper-V Cluster Node-A and Node-B

Win2012R2 Standard FileServer, sharing a bunch of VHD files via UNCPATHNAME.vhdx

PATH shared folder and Security NTFS permissions allowing Everyone:F, SYSTEM:F, Node-A$:F and Node-B$:F, full control, open permissions at the highest level

I´m connected to TS/RDP to Node-A and if i try to create a new VM it succeeds!


If i´m connected via TS/RDP to Node-A, AND ALSO using the Hyper-V Manager pointed to Node-B

i got the access denied error  0x80070020

Again, i´m conencted  to the TS/RDP Node-A, but the hyper-V manager is pointed to Node-B (Node-B has more resources available)

Why is that?

Maybe a COM problem?
