In general, unless all devices would be statically allocated, it would be impossible to guarantee certain vnet name. However, what you can do is to create the device yourself and then just tell libvirt to use it: <interface type='bridge'> <source bridge='vnetX'/> </interface> But most likely, the problem you are trying to solve looks for a different solution. If you need the device name in order to set up some environment (e.g. apply some FW rules on the device), we have network hooks and domain hooks - user defined scripts that are run by libvirt on various events (e.g. domain startup, device hotplug, etc.). You should consider those. Michal _______________________________________________ libvirt-users mailing list libvirt-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvirt-users
