Hi,
Hi :-)
I've been migrating VMs using the web administration but I need Power
Management on each host so that the engine detects that a host is
down, right?
Yes, it needs to be fenced.
Regarding the topic of this mail which grabbed my attention.
when I think about HA and oVirt I think about the following :
- oVirt Engine/RHEV-M can failover to an other host
- The shared storage is also available on the other side.
I've been testing migrating Engine in case it fails in a POC
by putting Engine in a KVM VM under control of pacemaker and
DRBD to drop the need of shared storage.
The storage part is something I haven't found a solid solution
for. Maybe with DRBD, but there must be a better way i think.
