Hello Folks,
What is your Favorite features in Hyper-V 2012 R2?
Well there are many features to choose from :)
Thanks to Ben, Hyper-V Program Manager which provided us with a cool feature that makes our life easier called Cross-Version Live Migration.
The process supports moving a running Virtual Machines from a server running Hyper-V in Windows Server 2012 to a server running Hyper-V in Windows Server 2012 R2 only but not vice versa!
Today I came across a weird issue during this process.
Here is the scenario:
I started upgrading my current hosts from Hyper-V 2012 to Hyper-V 2012 R2…
I have prepared a new box with Hyper-V 2012 R2 ready to run the workload.
From my Windows 8.1 management station, I initiated the moving process for a running VM from Hyper-V 2012 to Hyper-V 2012 R2…
And here is the Error :(
Note that to initiate a Live migration from a Management station, you need to have Constrained Delegation enabled in Active Directory.
Let’s check again in Active Directory to see if Constrained Delegation is enabled:
Host A Source Hyper-V 2012:
Host B Destination Hyper-V 2012 R2:
Everything looks good so far…
Let’s check if Kerberos is selected in each Hyper-V host.
Host A Source Hyper-V 2012:
Host B Destination Hyper-V 2012 R2:
Mummmmmmmm… All is well,
Let’s see if the Virtual Machine Management Service is running in each host.
Host A Source Hyper-V 2012:
Host B Destination Hyper-V 2012 R2:
Everything looks great :(
Since the Cross-Version live migration process will be initiated from Host A Source to Host B Destination.
Let’s stop and start the Virtual Machine Management Service on the source Host A.
Net stop vmms
Net start vmms
Here you go, the moving operation is succeeded now :)
Hope this has been useful.
Until next time… Enjoy your day!
Charbel,
