Hi everyone, With more cloud infrastructure providers using KVM than ever before, the importance of having FreeBSD performant as a guest on these infrastructures [1], [2], [3] is increasing. It seems that using Virtio drivers give a pretty significant performance boost [4], [5]. There was a NetBSD driver, and there seems to (have been) some work happening to port this to DragonFly BSD at [6] and [7] -- does anyone know if this code is stable, or if it has stalled, or if anyone's working on it? It may be possible to use the work done on the Xen paravirtualised network and disk drivers, combined with the NetBSD code, as starting point for an implementation? My company might soon be in a position to sponsor the work to get this completed and available at some point in FreeBSD 8. I'd be very interested to hear from anyone who's involved, or who might like to be. -- Best Regards, Luke Marsden CTO, Hybrid Logic Ltd.
