<font face="arial, helvetica, sans-serif">Hello folks.<br>
<br>
</font><font face="arial, helvetica, sans-serif"><font face="arial,
helvetica, sans-serif">Ou oVirt (</font></font><font

which runs in one Datacenter and controls Nodes locally and also
remotelly lost communication with the remote Nodes in another
Datacenter.<br>
To this point nothing wrong as the Nodes can continue working as
expected and running their Virtual Machines each without
dependency of the oVirt Engine.<br>
<br>
What happened at some point is that when the communication
between Engine and Hosts came back Hosts in the remote
Datacenter got confused and initiated a Live Migration of ALL
VMs from one of the hosts to another. I had also to restart
vdsmd agent on all Hosts in order to get sanity my environment.<br>
<br>
What adds up even more strangeness to this scenario is that one
of the Hosts affected by the need of restarting VDSM doesn't
belong to the same Cluster as the others and had to have the
vdsmd restarted.<br>
<br>
I understand the Hosts can survive without the Engine online
with reduced possibilities but can communicated between them,
but without affecting the VMs or even needing to do what
happened in this scenario.<br>
<br>
Am I wrong on any of the assumptions ?<br>
