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?

Yes. You can use default Linux bridge networks. Create an OVN overlay network with subnet for VMs. Then create a "router" VM that is connected to both overlay and a physical network, configure routing there.

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

Thanks, will take a look.
