I seem to have lost the wiki login/password.
For virtio-pci, Virtio 1 mode can now be enabled by specifying
disable-modern=false. To suppress the legacy interface and
create a non-transitional device, specify disable-legacy=true
additionally. All devices support this mode.
This support is still experimental: it functions fine in normal
usage and so should be appropriate for guest driver development, but
there
are known issues around migration, guest out of memory handling, and
performance.
When used with virtio 1, virtio blk no longer supports scsi
command passthrough. Please use virtio scsi instead.
