We have been having issues where we cannot Live Migrate to some of our hosts. I have verified the VMM Agent is the same version and the Host OS are the same. I've compared all settings in VMM and Hyper-V between hosts that are Live Migration Candidates against hosts that are not Live Migration Candidates.  The Rating Message for those that we are unable to Live Migrate to is the following:

 Unable to migrate or clone the virtual machine "" because the version of virtualization software on the host does not match the version of virtual machine's virtualization software on source (6.3.9600.17334). To be migrated or cloned, the virtual machine must be stopped and should not contain any saved state. 

Any help resolving this is greatly appreciated!

Smells like your Hyper-V version or patch level is different.

Or your SCVMM agents on the machines are at different levels.

Or, the integration components in the VM are not updated to match the host.

Hi Brian! I greatly appreciate your help! I'm a total noob to VMM. Something else to note, I installed all Windows Updates on the VMM Server, including VMM Rollup 5. So, after doing this, I thought I should install all Windows Updates on our test host, after doing so, the VMs could not be live migrated to ANY hosts. Prior to installing updates on the VM's host, there were some hosts that it could be migrated to.

Again, being a noob...what do you mean by integration components? I've verified the SCVMM agents are the same version.

Thank you so much!

If you check your agent status - you should see that there is an agent update that needs to be done.

SCVMM can push this out, but you need to instruct it to. 

Go to the hosts view, select a node, right click, push the updated agent

A few questions..

Are you doing shared nothing live migrations?

What version of VMM are you running?

Can you perform the live migration using Hyper-V manager or failover cluster manager if a cluster?

What version of Hyper-V is the source and destination?

Did you upgrade the host ?

What OS is have the issue live migrating ? Are they the same?

In VMM you can add the column to show what version of the integration services the guest is running and under the fabric section you can see if the Hyper-V hosts are up to date

Hi,

i have also a few questions. You say, that you are the total noob. Therefore you should check the total noob things :)

• What Version of SCVMM are you using?
• What about your infrastructure? Hyper-V Cluster? And how many Cluster?
• Are you trying to migrate between Hyper-V Cluster? Or between Cluster nodes?
• Are the VMs made high available on your Hyper-V Host?
• Does the target host have access to the shared volume?
• did you check the processor version?

• Check the Patch Level of the Hosts and the Agents
• Are source and destination host the same OS Version and Patch level? Are they both in the same Cluster?

without knowing more about your infrastructure i could ask a lot more questions. It would be cool if you could give us some more information about your setup. OR let us know your solution if you are able to fix the problem.

regards,

Do you have enough resources on the other host?
