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

[Peter]

I cannot get the HE to run on node1.  I did 'hosted-engine -vm-shutdown'
on node2.  After it was down I did 'hosted-engine --vm-start' on node1
but did not even get a qemu process.  I did 'hosted-engine
--vm-poweroff' on node1 and 'hosted-engine --vm-start' on node2 and got
it up and running again.

How do I get the HE storage domain imported to the engine to fix all of
this?  Is it a database thing?

Thanks,
Peter

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.
