You mean I should define hook scripts for such network setting?
and in case of using OVN, can I use direct ovn commands or related (neutron)rest API
calls for it instead of vdsm hooks?
At least you could try to create a vdsm hook that does whatever you want - this is just a
script.
last one, could you please explain in more detail about floating IP..
I couldn't understand relationship with the VLAN and I'm wondering whether I
should assign host network IP to VM for public communication.
Floating IP is an IP that you use for Highly Available resources. You need both VMs to be
in the same VLAN.
For example:
VM1 - 192.168.0.1/24
VM2 - 192.168.0.1/24
Floating IP - 192.168.0.200/24
