I had this long running discussion on kvm devel list, trying to argue for 9p as the interface for paravirtual devices. I think there is some acceptance, but not total acceptance. People keep thinking that emulation is the same as an abstraction. i.e. they argue that an abstraction of an IRQ controller that has IRQ0-n, NMI, SMI, etc. The abstraction is that the highest IRQ is not bounded as it is in real life. Abstraction? Hmm. Not on my planet, anyway. It hit me that the dom0 could export its tcp stack to dom1 as a paravirtual device. you could bypass the silly virtual enet emulation that way. Your /net would go right to the tcp, not via some odd pseudo-device. That would save some delay and overhead, and, not incidentally, would make my mp3 player smoother in dom1 ... thanks ron
