Here are a couple of ideas that would yield more information: Since the console still works I suggest checking dmesg output inside the guest. Are there any error messages at the bottom? Try pinging the host's IP address from inside the guest. Run tcpdump on the guest's tap interface from the host and observe whether or not you see any packets being sent from the guest. rmmod virtio_net inside the guest and then modprobe virtio_net again. See if network connectivity is restored (remember to rerun DHCP or whatever, if necessary).
