This reverts commit d2e5538b. A migration regression was introduced by this commit. When migrating a domain, its active XML is sent to the destination libvirtd, where it is parsed as inactive XML. d2e5538b copied the libxl generated interface name into the active config, which was being passed to the migration destination and being parsed into inactive config. Attempting to start the config could result in failure if an interface with the same generated name already exists. The qemu driver behaves similarly, but the parser contains a hack to skip interface names starting with 'vnet' when parsing inactive XML. We could extend the hack to skip names starting with 'vif' too, but a better fix would be to expose these hypervisor-specific interface name prefixes in capabilities. See the following discussion thread for more details https://www.redhat.com/archives/libvir-list/2015-December/msg00262.html For the pending 1.3.0 release, it is best to revert d2e5538b. It can be added again post release, after moving the prefix to capabilities.
