This plan looks good to me.

As Pekka mentionned, I'd also like to have a conversation of how far we want to
push virtualized driver features. I think KMS support is a good feature to have
to spin up a VM and have all of the basics working. However I don't think it's
a good idea to try to plumb an ever-growing list of fancy features
(seamless integration of guest windows into the host, HiDPI, multi-monitor,
etc) into KMS. You'd just end up re-inventing Wayland or RDP on top of KMS.
Instead of re-inventing these, just use RDP or waypipe or X11 forwarding

So I think we need to draw a line somewhere, and decide e.g. that virtualized
cursors are fine to add in KMS, but HiDPI is not.
