I'm seeing this issue as well. I have a Hardy host system, with bridged network. I start a lucid 64 bit kvm with virtio and a tap device (which is in a bridge already) and after a while, the network seems down (from outside, no ssh access etc). However, when I run a ping from within the kvm instance, the network works again.
