Hi David,

Which PV backends do you care about? We already have net, block and console

Well, this is all what we need, actually. Even console only will be
sufficient, as we are using QEMU to provide virtio-pci backends, so both
storage and networking should be provided by virtio. Are you proposing
to just drop this patch at all? I believe we can live without it, yes.

Yeah, I think you can drop anything that's only needed for the legacy backends. 
I'm tempted to make a separate config option to compile those out.


I think that would be a good idea. The other legacy bacckend that we may need to care about is xenfb... not so much the framebuffer itself, but the mouse and keyboard aspects. The XENVKBD and XENHID drivers expose PV mouse and keyboard to Windows instances so it's be nice if we can avoid the backend withering away.
