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?<br></blockquote><div>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.<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
