[$] Virtio without the "virt"
When virtio
was merged in Linux v2.6.24, its author, Rusty Russell, described
the goal as being for "common drivers to be efficiently used
across most virtual I/O
mechanisms". Today, much progress has been made toward that goal, with virtio
supported by multiple hypervisors and guest drivers shipped by many operating
systems. But these applications of virtio are implemented in software, whereas
Michael Tsirkin's "VirtIO
without the Virt" talk at KVM Forum 2019 laid out how
to implement virtio in hardware.
