I tried, but my vm didn't get ip address..

Just skip the subnet step. Create the network, connect it to physnet and attach a VM.

Thank you for fast response. Ok, for example, i gave subnet to my ovn network 172.20.139.108/30 and my vm get ip 172.20.139.110. After that i tick connect to physical network ovirtmgmt(all vm's in this network has ip 172.20.139.x). I don't have ping between vm 172.20.139.110(from ovn network with subnet) and 172.20.139.x (from physical network ovirtmgmt). What shoul i do to get communication between them?

You should not assign a subnet to external provider network connected to physical network. I think both physical and OVN DHCP servers will work, but I'm not sure which one has priority.

If you have DHCP server running on your ovirtmgmt network, just create a network on external provider and connect it to the ovirtmgmt. Then VMs connected to this network should obtain IP from ovirtmgmt DHCP server and they should be able to ping one another or ovirtmgmt interface.

Hope that makes it a bit more clear.

You are right, but one little thing, i think that ovn has his own dhcp service.. Am i right? Could you please tell me some words, how does work option when i tick connect to physical network? For example, can i ping vm's from ovn network to ovirtmgmt, or how does it work?
