Hmm... Well something is wrong because I just get a black screen. I
don't even get the BIOS messages since I updated this morning.
Downgrading back to the fedora-updates version of qemu makes it work again.
BTW the trigger for that warning seems to be that I have
listen='0.0.0.0' set on the vnc adaptor to allow connections from remote
machines, which causes libvirt to build a qemu command line with "-vnc
0.0.0.0:0".
