OK, so it is done by libvirt. However, I was trying to reproduce this
and I was looking in the code and it looks like your config file
settings are not reflected in libvirt (does the ownership change also
after libvirt restart?). There is no chown called when dynamic ownership
is turned off. The only thing I haven't tried is checking older versions
of libvirt, but this code haven't changed that much.
