[ovirt-users] hosted-engine migration problems on 3.6, 3.6.1, 3.6.2

[Martin Sivak]

Hi,

we really need more logs. Preferably the full agent, vdsm and engine
log around the time the migration is attempted.

The warn/error messages are all related to the fact that hosted engine
runs in the "3.5 mode" with the storage domain not being imported to
the engine yet.

If all VMs and HE are running on node1 and I try to put it in maintenance the VMs will migrate but the HE will not and node1 will show 1 VM remaining on the node (even though the HE VM doesn't show up in the VM list) and will not go into maintenance.
