Hmm, all the command seem to complete quickly. But then libvirtd's poll loop
keeps hitting a 5 second timeout. I can't reproduce anything like that here

Do you have any way to try older libvirt versions? Might be interesting to see
if this is a regression, or just something specific to your setup.
