Hey, this is definitely a libvirt bug. Since 3.1.0 libvirt spawns each
qemu in its own mount namespace so that it can have private /dev mount.
I've heard that there are some issues with AppArmor - is that what are
you using? Can you try the current git HEAD - there were some fixes
applied after 3.1.0 release.

Meanwhile, you can disable namespaces by setting:

  namespaces=[]

in qemu.conf. However, that should be just temporary solution until we
fix all the bugs.
