Hi Arik,

Yes, my problem about cpu type, seems linked to the fact i've upgraded a host in 8.3 before ugprade ovirt in 4.3...

I've done another test, for my problem of vm migration.

I start a guest directly on the 8.3 nodes then it can be migrate from/to 8.2/83.
I've also tried to force it to start on a 8.2 nodes then migrate to 8.3 nodes, and it also work.

So it seems a full power cycle on guest resolve issue.

Ok for opening a bug on vdsm, could you please let me know where?

Thank you.

Hi

thank you it's work now. All my host 8.2/8.3 are up and running. During reactivation of 8.2 host i saw the log line "updating cluster CPU..."

Good to see that it works for you now (the credit to Lucia).

So the cluster configuration didn't change because not all hosts were UP when starting the 4.4.3 engine?

I tried to move guest from 8.2 host to 8.3 one but it failed.

Engine.log :

The migration probably fails due to incompatible CPU flags - please file a bug and attach VDSM and libvirt logs from both source and destination hosts.

Another think i've noticed on event log of 8.3 host :
VDSM bombur-adm.cines.fr command SpmStatusVDS failed: Cannot inquire Lease(name='SDM', path='/dev/7586152d-338c-415d-93f4-74efd09c02fa/leases', offset=1048576): (2, 'Sanlock get hosts failure', 'No such file or directory')

But file seems to exist on host :
ls -l /dev/7586152d-338c-415d-93f4-74efd09c02fa/leases
lrwxrwxrwx. 1 root root 7 Dec 15 14:14 /dev/7586152d-338c-415d-93f4-74efd09c02fa/leases -> ../dm-7

I tried to reboot host & restart engine, set my 8.3 host as SPM ... same error.
