...keup it waits for 64 packets or timeout before processing them. This might cause the guest to run out of tx buffers while the host holds them up. This is a temporal solution to quickly bring back performance to 800mbps. But a better fix will soon be sent (its not the only problem).

...try to use backport scripts that automatically backport virtio to older guest kernels >= 2.6.18. It was written by Anthony Liguori and was decorated also by Avi and myself. Seems to work reliably with kvm, should do the same trick for lguest. You can download it from git://kvm.qumranet.com/home/dor/src/kvm-guest-drivers-linux Anthony, you can update your mercurial repository with our changes.
