[ovirt-users] Re: VM migrations failing after upgrade 4.3.2 -> 4.3.3

Hi, this is a bug:  https://bugzilla.redhat.com/show_bug.cgi?id=1696621 It happens when a migrated VM has missing CPU load. Do you have some special VMs without updated CPU load, or VMs that were recently started?  Regards, Andrej On Wed, 17 Apr 2019 at 11:08, Eduardo Mayoral <emayoral(a)arsys.es <mailto:emayoral@arsys.es>> wrote: Hi,     After upgrade to 4.3.3 from 4.3.2, VM migrations are failing with "No available host to migrate VMs to"     Interestingly, this happens in one of our clusters, not on the other. Both on the same datacenter, both in 4.3 compatibility version.     This are the relevant lines from /var/log/ovirt-engine/engine.log 2019-04-17 08:58:41,816Z ERROR
