[ovirt-users] All host non operational after engine upgrade

[Jonas Israelsson]

Greetings.

Upgraded my Engine from a pre 3.6 version (not sure about the version, 
but it's only a month old or so) to RC today and found to my great 
surprise all hosts marked as Non Operational.

The cluster working fine just hours ago now have some mismatch with my 
hosts CPUs. The cluster is set to Opteron G4 and all hosts CPU have 
Opteron 4226 installed.

[org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector]

The error above look qemu to me so I tried reinstalling one of the node 
with the latest Ovirt-node snapshot downloaded from Jenkins --> 
http://jenkins.ovirt.org/job/ovirt-node_ovirt-3.6_create-iso-el7_merged/lastSuccessfulBuild/artifact/exported-artifacts/ovirt-node-iso-3.6-0.999.201510190928.el7.centos.iso

That made however no difference.

I could use some help..

TIA
