That doesn't really have any impact. If a desktop user is logged
in, udev may change the ownership to match that user, but if they
aren't, then udev may reset it to root:disk. Either way, QEMU
may loose permissions to the disk.
Then if you create a guest without being in the 'disk' group, it'll
fail.  That's pretty expected AFAICT.
We don't *ever* want to put QEMU in the 'disk' group because
that gives it access to any disk on the system in general.

If that's what the user wants to do, what's the problem with doing it?

Setting the global user/group is not enough because just because you have one VM that you want in disk doesn't mean you want all of them in disk.

And to be clear, if you could do this today, there wouldn't be a problem here in terms of QEMU just reopening the file.
