OK, it works fine for me locally.  I can only guess that there is a rule or
something that is not properly setup for you.  So let me get a bit information
from you:

1)  brctl showstp virbr0
2)  iptables -L ; iptables -t nat -L
3)  cat /proc/sys/net/ipv4/ip_forward

If it is indeed something to do with iptables (as I suspect), then the
following *might* help out:

$ sudo virsh net-destroy default
$ sudo virsh net-start default

Let me know if that helps, and if not, please give me the information from
above.

Thanks,
