Hi Nardus,
You might have hit an issue I have been hunting for some time ( [1] and
[2] ).
[1] could not be properly resolved because at a time was not able to
recreate an issue on dev setup.
I suspect [2] is related.
Would you be able to prepare a thread dump from your engine instance?
Additionally, please check for potential libvirt errors/warnings.
Can you also paste the output of:
sudo yum list installed | grep vdsm
sudo yum list installed | grep ovirt-engine
sudo yum list installed | grep libvirt
Usually, according to previous reports, restarting the engine helps to
restore connectivity with hosts ... at least for some time.

regards,
Artur
