Well, it's not the same as trusting a Domain's filesystem to be proper.
But it still requires trusting that there are no exploitable bugs in the
software.
Except that the attacker never gets his hand on any of this data. It is
like telling you to exploit my mother's win95 box without the network or
the keyboard being plugged in.
Using a lesser-user to create the domain within Domain-0 requires
trusting there are no exploitable bugs in the kernel syscall interfaces.
So, it's a point of failure as much as Linux is.
Well, I do not agree with you there.
Anyway, this code is already written for Xen 1.3. You can find it at

Awesome! This is pretty cool stuff. Do you have plans to update for Xen
2.0/Linux 2.6? Kernel-driven migration seems like an appealing topic.
I would like to, now that it seems xend is going to be slimmed down.
However, my time to work on this is a bit limited for the next six
months :-(
thanks,
Jacob
