I have a problem with the Interface external_ids:iface-id property in OVN To configure an ovs port on the host for OVN, you need to set the value of this property to the name of the Logical-Switch-Port from the NorthDB: ovs-vsctl add-port br-int lport1 -- set Interface lport1 external_ids:iface-id=sw0-port1 This is using the name, not the id. Specifying the id does not work. This is ok when you do it by hand, but is inconvenient when you try to automate it. Libvirt offers a chance to automate deployment of ovs connected nics, but it only accepts an UUID value, so using the name makes this impossible. Would it be possible for OVN to interpret both values (I realize this would cause some issues)? For reference, the way to set this in libvirt xml: <interface> ... <virtualport type='openvswitch'> <parameters interfaceid='lsp-name'/> </virtualport> Using the name results in: libvirtError: XML error: cannot parse interfaceid parameter as a uuid Another disadvantage is that this forces the LSP name to be unique, unlike for example Logical-Switch names, which can be duplicated. We have a workaround, but it causes some unneccessary complications.
