[ovirt-users] Re: cannot live migrate the hosted engine
If this is an oVIrt 4.4 , then open a bug on bugzilla.redhat.com .

Hi,
Found it,
The hardware is identical (3xhp microserver g10, identical disks, cpu and ram)
It is a hyperconverged setup and all hosts have access to the engine shared storage they
are all marked with a silver crown.
The hosted engine is the only vm that is running.
Even though the vm was capable of running on each machine (tested that by manual migrating
it), the ovirt engine decided that it could not migrate the vm based on the vm specs.
After reducing the max ram (not current ram) and virtual cpu's it was capable of live
migration.
Weird that ovirt decided that no hosts matched even though they were identical.

Hi Rob,
I would check the vdsm logs on the host where the HostedEngine VM was already running
(source).
Also , you can check the logs on the HE itself.
In the UI, check the cluster cpu settings and your hosts. Is it possible that one node
has newer CPU than the other ?

Hello,
In my hyperconverged environment I cannot live migrate the hosted engine.
However shutting down the hosted engine then starting it on another host works fine.
This is the only way to migrate the engine to any of the hosts that are configured for
the engine.
I can't seem to find anything in the logs and hosted-engine vm-status doesn't
tell me anything.
Anybody any ideas where to start looking ?
Rob
