So is qemu-kvm-rhev from mentioned source RPM a drop-in replacement for qemu-kvm from CentOS ? Would it make sense to install it instead of qemu-kvm?
That's the way it worked for me.
- Put one host in maintenance - Install *-rhev packas on that host yum localinstall qemu-*rhev*.rpm) this replaces the regular packages: Nov 06 16:15:38 Installed: 2:qemu-img-rhev-0.12.1.2-2.355.el6.9.x86_64 Nov 06 16:15:40 Installed: 2:qemu-kvm-rhev-0.12.1.2-2.355.el6.9.x86_64 Nov 06 16:15:40 Installed: 2:qemu-kvm-rhev-tools-0.12.1.2-2.355.el6.9.x86_64 Nov 06 16:15:40 Erased: qemu-kvm-tools Nov 06 16:15:41 Erased: qemu-kvm Nov 06 16:15:41 Erased: qemu-img - Restart vdsm, enable host migrate test VM to host, test live storage migration: OK - Put host back in maintenance and reboot. - Activate host and repeat maintenance/installation steps with other hosts.
The "solution" for the live snaphost problem as proposed in https://bugzilla.redhat.com/show_bug.cgi?id=1009100 is:
|BZ| Vdsm should check (hopefully via libvirt) if the underlying qemu supports live snapshot, and report this feature to Engine. |BZ| If it does not, block this feature in UI.
That is something that should be implemented, however, there should also be some way to use a full-featured kvm with oVirt.
Can oVirt carry the qemu-*rhev* packages? Or is this something that should be in epel? Or CentOS?
I think worth veryfing with centos first on their plans to carry this package before we carry (and maintain it) in ovirt repos.
