 Replying to [comment:1 krstic]:

 Also, for what we actually want to do, Xen doesn't really make sense. We
 don't want to paravirtualize; we just want to isolate a few separate
 contexts running on the same machine. It might be that we can get away
 just with MAC and/or ACLs.

 The issue is that service administration then gets tied together: you have
 to deal with one integrated whole release, and can't update the different
 needs of content management, school administration and kid's use of the
 system.  This will make overall administration much more difficult, if
 these cannot be kept well isolated.

 The issue is the Vserver (or equivalent) patches may be more invasive than
 the full virtualization. It does sound like there may be some more
 progress on inclusion of Vserver or similar technology  than the time I
 entered the original trac item.

 At some point, we're going to have to make a call on which tack to take:
 but I think we have our hands full for the next few months, by which time
 it may be clearer which way the wind is blowing. And the Princeton folks
 now have PlanetLab running on OLPC hardware, so they will have more
 experience of what operations on a much smaller platform than the larger
 servers they are used to works.
