VirtualBox 3.1 BETA - VirtIO - Part II

FYI: VirtIO devices has not only network, but also block device (or
storage). It acts similarly to SCSI controller, but has more
This again is supported by both Linux and Windows guests. VirtIO-block
can be used as a bootable device.

VirtIO network, in my own benchmarks, achieves 1.1 Gbps of bandwidth
between Linux host and Linux guest. (if the kernels are configured
properly, otherwise performance drops below Intel E1000 levels).

3. Documentation:
section 6.1 needs some update for VirtIO.

As for Linux distros, that do work: openSUSE 11.0+, Fedora 9+, Ubuntu
8.04 LTS+, RHEL 5.3+. First three has kernel 2.6.24+ and the last one
has custom driver backport to 2.6.18 by Red Hat.

"+" means this version and up.
