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 <tap>" for the guest's tap device on the host. If you see "RX dropped" > 0 then the virtio-net device is stuck. -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
