The strange thing is, if I power down a VM and then move it to the new host, I can power it back up successfully. I need to rebuild a few other hosts, so just nervous that if I place one of them into maintenance, the VMs are not going to migrate to the new host.

So The compatibility in the Cluster is fine. The initial CPU type was set to Intel Westmere IBRS SSBD Family, but I have since changed it to Intel Broadwell Family, as the destination server is compatible with Broadwell.

 

Is there a way to get the migration working without editing each VM? Or should I just make the jump and rebuild another host that’s CPU is Intel Westmere?

 

Thanks

Hi,

Change vm cpu in edit mode.

Try again.

Also check cluster and datacenter compatability.

Hello Everybody,

 

I am having a strange issue. When I try and manually migrate a VM from one host to another, I get an error stating:

 

“Migration failed  (VM: VM1, Source: node6.example.com, Destination: node3.example.com)”

 

I have tried with a few different machines, and it pops up with the same error. I have attached the VDSM logs of both source and destination nodes. The time frame is 16:01

 

I see the below in that time frame, but not quite sure what I need to change:
