VMM08 and Unable to migrate

Hi again




We have an Hyper-V environment with 46 VM.
We have VMM08 to control them.

We try to move VM from a host to another an I got this error:


Unable to migrate the virtual machine sw2k8av because the version of virtualization software on the host sw2k8dtc01.cartv.int (6.0.6001.18125) does not match the version of virtualization software on the source host (6.0.6001.18221). To be migrated, the virtual machine must be stopped and should not contain any saved state

If you look for the vmms.exe in the c:\windows\system32 directory:


The vmms version is different.
The guilty?
The Microsoft update.
One machine had the update service up, the other one it had'nt.
So I need to update the both machines.

NOTE: I refresh the vmm08 mmc in the client. If you won't do it. The error continues, even you had upgrade both hyper-v servers.

You can read more information :(spanish link)
