Does KVM allow passing through a full multi-function PCI device to a guest, and make that device appear as a whole multi-function device rather than as multiple PCI single-function devices (e.g. Xen only does the latter where all PCI devices appear with function ID being 0 in the guest)?
Thanks,
Anna

Not that I know of. It shouldn't be difficult to add though - all the
necessary changes should be in qemu, not the kernel.

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
