--- Comment #13 from Stefan Hajnoczi ---
Michael Tsirkin and I are currently looking into a similar case. The bug can
be triggered when the guest transmits large packets using GSO. As a
workaround, try turning off TX offload features inside the guest:
# ethtool --offload eth0 tx off
# ethtool --offload eth0 tso off
# ethtool --offload eth0 ufo off
# ethtool --offload eth0 gso off
If the guest is already broken you can check whether it's the same bug by
looking at the output of "ifconfig " for the guest's tap device on the
host. If you see "RX dropped" > 0 then the virtio-net device is stuck.
