I've not reviewed the virtio patches but think I've gathered the gist of what they're doing (puppies would probably help here)... > On Sunday 10 June 2007, Avi Kivity wrote: > > There are probably more.

It'd be fairly trivial to make something like this call out to a variety of potential paravirt implementations - much of the code was effectively boilerplate (setting up char device, dealing with magic close character, etc). Taking this further, it'd be quite easy to make a "null" implementation that does what softdog did. Watchdogs grow from puppies, so I'd think this would suit Rusty quite well ;-) > * tty ports (not just console) to attach to via host socket > * alsa > * hostfs (UML like) My XenFS project is somewhat like hostfs but it's a) a bit hairy and b) not done yet :-) A simpler hostfs-style filesystem would be useful and a better target for testing out virtio. The main thing XenFS would want that I guess other virtio devices mightn't want is support for persistently sharing memory between virtual machines... In the Xen case this is less trivial than the UML hostfs case. It's not *needed* yet, I just thought I'd throw it out there as a potential future thing. Presumably virtual block devices that do memory sharing might need this sort of facility too. Cheers, Mark -- Dave: Just a question. What use is a unicyle with no seat? And no pedals!
