Actually I'm looking into an issue with OpenStack / Libvirt
manipulating
LVM as an image backend. When the logical volume is created, udev rules
will set the ownership to root:disk. After libvirt actually starting an
instance, device node ownership will change to qemu:qemu by libvirt. Then,
if you stop an instance, the device node ownership will change back to
root:root. Seems there's some inconsistency here.
This is actually a well-known bug in libvirt.

I will try to get this made non-private)
You can turn off libvirt's ownership management (set dynamic_ownership
= 0 in /etc/libvirt/qemu.conf) however this will cause other problems.
I don't think there is a proper solution to this yet.
