Hi,
Pratyush and I have been working on the virtio drivers. The virtio-blk
driver is ready for more testing and eyes looking at the code. The
virtio-net driver is still in progress.
I can't guarantee it won't panic your system, but it has survived a
couple hours of "fsstress" testing.
Here's some simple DD-based performance numbers compared with an
emulated IDE driver:

You can find the code at:

The wiki has some notes about it: installing, architecture, porting
notes, etc:

Thanks,
