The main reasons I still see people using virtio-mmio for the 'virt' board are: * still using old but working command lines * newer setups that were put together working from older tutorials that recommended virtio-mmio because they predated virtio-pci support being widespread * using older (eg distro) kernels -- for 32-bit kernels in particular it was a while before the virtio-pci support got built in the default configs I think, and then longer again until those got into stable distro releases I wouldn't be surprised if some of those applied also to via-OVMF boot setups as well as direct kernel boot. So it depends a bit what your tolerance for breaking existing user setups is. thanks -- PMM
