[Qemu-devel] VirtIO Net driver for Ubuntu 11.10

We recently ran an Ubuntu 11.10 VM which was installed with VirtIO NIC driver. 
The VirtIO net driver came from the Ubuntu's default package. The VM we 
installed was configured as a bridge mode. When we ran the Iperf test against 
the VM, the network interface of the VM was fairly unstable. Sometimes, the 
network interface of the VM could not receive the packets and we needed to 
bright the network interface down and up in order to make it work. After we 
replaced the VirtIo Net driver with ne2k driver and it worked quite stably now.

We know that the performance of virtIO is much better than ne2k in virtual 
environment. We would like to use virtio driver instead. If this is the virtio 
driver issue, can you tell us where to get the latest virtIO driver for Ubuntu 
VM? Otherwise, tell us how to make the virtio net driver work in Ubuntu VM if 
you have ever had similar issue before.

The version of Qemu installed in Ubuntu is 0.14.1.
