[ovirt-users] [ovirt-devel] How to add ovs-based VM in version 4.0.2? Thank you

[Petr Horacek]

If the host was a part of legacy cluster you must do manual cleanup of
all networks. Currently VDSM cannot change Linux bridges into OVS ones
(this will be implemented soon). Make sure that you are adding clean
hosts (with NIC interface/s only) to OVS cluster.

Regards,
Petr
