When we want to create a full VirtIO based machine, we're still missing graphics output. Fortunately, Linux provides us with most of the frameworks

So this is a frame buffer backend written for VirtIO. Using this and my
patch to qemu, you can use paravirtualized graphics.

What does this do that cirrus and/or vmware-vga don't?

Work on non-MMIO machines.

This is especially important on machines that can't do MMIO, as all current
graphics implementations qemu emulates I'm aware of so far fail here.

s390 virtual desktops?

Well - have you ever tried installing SLES / RHEL on an S390? If not, give it a shot and comment again :-)
