Greg,

You can certainly have the two peacefully co-exist.  As a matter of
fact, at one point, xCAT had support for provisioning via SystemImager.
 xCAT has undergone a major revision since, and it's not currently an
officially supported option.

Details -- at this point, neither one knows about the other, so it is
possible for them to step on each others toes.  Especially with regard
to a handful of files/services that they both have the ability to
manage.  These include:

  * /etc/hosts
  * dhcpd.conf (or dhcp3.conf)
  * contents of /tftpboot

  (I think that's it...)

So, jumping into the way-back machine, I remember that the way we had
them integrated before was to allow xCAT to manage all of the things
above.  Then we simply had to get xCAT to send out the SystemImager
kernel and initrd, instead of the Red Hat install kernel and initrd (for
example), and off you go.

Hope that's enough to get you pointed in the right direction, but your
query has peaked my interest, and I expect I'll look into this again
soon.

Cheers, -Brian
