You can use RHCS inside two dom0's and one cluster service is a SW domU.
For this you need conga to setup a virtual server as a cluster service.
Spacewalk domU is a normal standalone guest with standart start/stop
scripts.
For this you need shared storage for domU.
There are the same conditions that you need for live migration between
to dom0's.
Here is a great article about this setup:

Hi,
What's about HA virtual server for spacewalk.
You can implement spacewalk inside a xen guest and make then this
guest with conga cluster suite ha to a other baremetal?
Well, the manuals/links posted here refer to active-backup/standby and
not to active-active/passive configurations using a HA solution such
RHCS.
I guess, it is possible to use RHCS for an AA/AP configuration of SW,
after all it is just another service. However, you will need to script
out your own startup scripts(stop/start/status for all the services SW
has) to use with RHCS on SW. Doable though. Anybody done it yet for
SAT or SW?
Alternatively, you can use XEN dom0 to live migrate an SW domU onto
another dom0. This should work for the embedded DB-SW offering, I am
not sure for the stand alone DB-SW...
