Re: [libvirt] [PATCH v16] support offline migration

From: liguang <lig.fnst(a)cn.fujitsu.com&gt; original migration did not aware of offline case, so, try to support offline migration quietly (did not disturb original migration) by pass VIR_MIGRATE_OFFLINE flag to migration APIs if only the domain is really inactive, and migration process will not puzzled by domain offline and exit unexpectedly. these changes did not take care of disk images the domain required, for them could be transferred by other APIs as suggested, then VIR_MIGRATE_OFFLINE must not combined with VIR_MIGRATE_NON_SHARED_*. and you must do a persistent migration at same time, do "virsh migrate --offline --persistent ...". Signed-off-by: liguang <lig.fnst(a)cn.fujitsu.com&gt; --- This patch is a combination of v15 from liguang and my changes I sent as review comments to that v15. Since I had to do quite a few changes, I didn't push the result right away even though this has my ACK now. I'll wait until next week and if no comments appear, I'll push this patch at the beginning of next week.
