"It's a shame that there's no middle ground."

What about para-virtualization and hybrid-virtualization? They are not the same as full virtualization (in fact have more in common to containers than full virtualization).

Current efforts on the virtualization "scene" are for the para-virtualization and hybrid-virtualization fronts (VT-x is a para-virtualization hardware helper). Full virtualization exists for ages and hasn't changed much.

You're right that paravirt is a step in the right direction. It still carries a ton of crap along with it though. You still need a full kernel with all the drivers, logging infrastructure, cron, inetd, and so on... If the paravirt crews do a really good job at getting rid of this unimportant junk (where unimportant means "not directly related to the application I'm trying to run"), I'll definitely sit up and take notice.

At the moment, though, there's little appreciable performance difference between Xen and KVM (for my apps anyway). And KVM is sooooo much easier to set up and run. So, although it doesn't improve my life much today, I agree that paravirt could potentially become an excellent solution in a few years.
