Hi Strahil,
I'm sorry to said I'm not totally agree with the VM pause behavior you mentioned
during healing, VM actually did not pause, but it heal very slow indeed about 1GB per
minutes, VM sync write operation appear slowing down when healing undergo. it is
comparative when sharding enabled.. chance to be paused is more offten when u do parallel
heal info at a time, it is also amplified pause situation when u have million shards.
I'd turn off regular heal info in ovirt, the pause situation almost gone.
