My own feeling is that the xenfb merge is very sensible, but I don't see
much of a win from merging xenconsoled, and the downside is that you then
need a qemu-dm instance for every PV guest. I think that requiring qemu-dm
for more 'featureful' PV guests -- framebuffer, USB, etc -- is well and
good, but someone who is running more minimal domU configurations --
console, net, block -- isn't going to want or welcome the rather unnecessary
per-domU overhead of qemu-dm.

So I think that qemu-dm for PV guests should be optional, and automatically
enabled only if a config option that requires qemu is enabled.
