Hi! I'm aware that (host side) vnetX are created when VM boots. But I'm trying to figure out a way ti create a persistence in vnetX names. What I mean is, say, I want to associate VMs vm0 to vnet0, vm1 to vnet1, vm2 to vnet2 and so forth, no matter which order the VMs are booted. I looked around network XML format, but did't find something... Since I'm using Open vSwitch as bridge, and it is controlled by my OpenFlow application, I can query for OF ports numbers based on port names (interfaces names). OVSDB can be used for such query, but the controller I'm using, Pox, has a limited support to it (stills in development). I'm using libvirt 1.0.5 and Qemu/KVM 1.4.2 on a Fedora 19 host. Thanks a lot in advance. -- Att Lucas Brasilino MSc Student @ Federal University of Pernambuco (UFPE) / Brazil twitter: @lucas_brasilino
