I posted this question on the libvirt-users list and here's the fix:
Instead of using:
conn = libvirt.openReadOnly(None)

I need to use:
conn = libvirt.openReadOnly("qemu:///system")

sh-3.2$ python
Python 2.4.3 (#1, Sep  3 2009, 15:37:37)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
  >>> import libvirt
  >>> conn = libvirt.openReadOnly("qemu:///system")
  >>> domains = conn.listDomainsID()
  >>> print domains
[14, 8, 13]

That wass the only change needed to make this work on the KVM server.

Thank you very much for your help with this, I appreciate it!
