Just out of curiosity.
What is the reason for not going virtio-pci? Is the PCI bus really
that expensive and complicated?
FWIW, I do not complain. When people start using virtio-mmio more
often this would also help virtio-ccw (which I am interested in)
as this forces people to think beyond virtio-pci.
