Dan,
if I catch you right, I dont need to switch to OVS for creation of internal networks with DHCP (for vms) and their routing to external networks. Thats true?

>>> After this step “Set OVS networking on all vdsm hosts. For each host, enable Maintenance mode, Sync All Networks” - my node01 disappeared. I don’t know what to do further.

After launch of network synchronization all settings of ovirtmgmt interface disappeared on node, after that node became unavailable.
