Alon,
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.
Thanks.
