Hi!

So you have different CPUs in the cluster? We once had a similar situation with Xen using 
live migration: Migration failed, and the cluster "wasn't that smart" handling 
the situation. The solution was (with the help of support) to add some CPU flags masking 
in the VM configuration so that the newer CPU features were not used.
Before migration worked from the older to the newer CPU and back if the VM had 
been started on the older CPU initially, but when it had been started on the 
newer CPU it could not migrate to the older one. I vaguely remember the details 
but the hardware was a ProLiant 380 G7 vs. 380 G8 or so.
My recommendation is: If you want to size a cluster, but all the nodes you 
need, because if you want to add another node maybe in two years or so, the 
older model may not be available any more. IT lifetime is short.

Subject: [EXT] [ClusterLabs] moving VM live fails?

Hi guys.

I have a resource which when asked to 'move' then it fails with:

  virtqemud[3405456]: operation failed: guest CPU doesn't match specification: 
missing features: xsave

but VM domain does not require (nor disable) the feature:

   <cpu mode='custom' match='exact' check='partial'>
     <feature policy='require' .....

what even more interesting, _virsh_ migrate does the migration live a ok.

I'm on Centos 9 with packages up to day.

All thoughts much appreciated.
many thanks, L.

This must go down - same environment - all the way, to the kernel. I knew that but forgotten - one box did change default kernel & after reboot booted with Centos's default as opposed to other boxes running with ver. 6.x.
So, my bad, not really an issue.
Thanks,. L
