Yeah, me too.
Ignoring technical questions for a moment, the main issue is that lhype
doesn't have an ABI; you have to run the same(ish) kernel as guest and
host. This is by design: I wanted it to be a platform for
experimentation and hacking, because I think we're still at that stage
with x86 Linux virtualization.
That's not to say that I don't think we can share code, it's just
important to realize that our aims are different.
Cheers,
Rusty.
