RFC: virtio blk driver

[Tim Bisson]

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,
