Neat! :-) It seems the GENERIC sparc64 kernel already has PCMCIA/CardBus ne(4), so adding 'ne* at pci?' might "just work". OpenBSD/sparc64 already supports sun4v LDOMS, so there's drivers implementing the virtual protocols (..vnet(4)/vdsk(4)). Does QEMU support this? Could the PCI virtio stuff be adapted to non-x86 architectures? -Bryan.
