Idea w/r/t virtualization -

Wouldn't it be way cooler if dragonfly had it's own KVM-like implementaiton that was implemented in a vkernel-like fashion?

started digging around in the VT-x instruction set a while back,
didn't get anywhere (Aach time!) - with the goal of writing a kernel module that added a syscall that added 2 numbers in a separate
virtual machine..

which could then form the basis of bootstrapping further..

seems to me like the VMspace API could be remapped to work against
the virtual machine instructions with not too much glue-code + ASM

etc, etc...

rather than supporting xen, which seems to be a much more complicated

this is all highly speculative, however..
