Comment 48 for bug 799997

The reason why it didn't allow it is because libvirt didn't handle spaces in the names well at the time. If libvirt handles it ok, then it would be ok to allow it in virt-aa-helper.c since libvirt quotes all its file rule paths in the .files (except I just noticed /dev/vhost-net-- it should probably be fixed to do that). You would definitely want to thoroughly test this because, as mentioned, libvirt itself had issues with this in the past.
