[libvirt] [PATCH] tests: Don't touch /dev/vhost-net in qemuxml2argvtest
The code is trying to open /dev/vhost-net from the host machine and if the
current user has access to it, the command line will end up having two more
options for an interface (,vhost=on,vhostfd=X where X is next free file
descriptor).
