I have faced with the same bug
When a VM using virtio-net driver receives too much network traffic, the network interface stops working.
Steps to reproduce -

On VM (with virtio-net):

% nc -k -l 0.0.0.0 4242 > /dev/null

On another machine (baremetal or VM):
% cat /dev/zero | nc IP 4242

After some time, the VM network will stop working. With 2 listeners on the VM, I succeeded to reproduce this issue in about 1 hour.

When I restart networking it working again

I am using next packages:
linux-image_3.2.0.23.25_amd64.deb
qemu_1.0+noroms-0ubuntu13_amd64.deb
