That error makes me think it's something to do with ipv6 vs. ipv4. But it's
tough to say without more details. Does this fail?

nc -l 127.0.0.1 5900

Try with -4 and/or -6 switches. If so, there's something wrong with your host
network configuration independent of qemu.

If that doesn't fail, I'd grab the qemu command line from
/var/log/libvirt/qemu/$vmname.log, and try to reduce it to a minimal
reproducer. Maybe something like:

qemu-kvm -netdev bridge,br=<BRIDGENAME> -spice port=5900,addr=127.0.0.1

You would need to alter the whitelist in /etc/qemu/bridge.conf for that to
work. Then stuff all the details in a qemu bug report.
