oops

there was a mistake paste:

I wanted to write:

---------------------------------

IIRC jail() can have name-space clashes when it comes to disk permissions and 
such.  This isn't possible on a XEN like system.  (I have to admit, I don't 
fully understand the scope of this clashing)

XEN allows me to do live suspends and resumes.  I can literally take a 
snapshot of a running OS, and resume it when I desire.  I can even migrate a 
VM over the network in such a live fashion.

the availability and flexibility is clearly higher
