Thanks!

Yes, I think there are lots of reasons to have something similar for desktop 
applications and it sounds like Hypervisor.framework in OSX is a great place to 
start.  I'm not sure about how much of the ukvm code would be reusable.  We 
ultimately want ukvm to be modular, so if there was a way to build a "unikernel 
monitor" out of made-for-Hypervisor.framework modules or made-for-KVM modules, 
that would be ideal!

Thanks; I'll try these suggestions in the next few days and will ask if I'm 
still confused :)
