it seems, that i encounter the same bug.

I've a guest with an high network load, and after some time, it seems that there's "no more network".

Under the guest, I can't ping anymore the gateway.
If i  restart the guest, everything work fine again.

How reproducible is this (and can you also recover the network by simply
rmmod/modprobe'ing the virtio_net driver)?  Tom posted a patch that you
could try if you have an easy way to trigger.
