Lol, yeah, I was gonna say...but thanks! Not sure if I'm into
implementing a patch vs. finding a way around this, and I'm wondering
why it reared it's head after an update to libvirt & qemu vs. earlier in
my testing -- makes me think it may be an unrelated, albeit similar bug.
Thanks again Juergen.
