CentOS virt - Jan 2012 - No module named cygvirtmod

I'm trying to set up a xen guest on a machine that already has a few others
 running (not set up by me). It fails with the following error:

+ virt-install -r 512 -n host5 -f /dev/vol0/lvol5 --nographics -p
--os-type=linux --os-variant=rhel5 --accelerate -l http://bla -x
ks=http://bla/ks.cfg -m MA:CA:DD:RE:SS
Traceback (most recent call last):
  File "/usr/bin/virt-install", line 31, in ?
    import libvirt
  File "/usr/lib64/python2.4/site-packages/libvirt.py", line 12, in ?
    import cygvirtmod as libvirtmod
ImportError: No module named cygvirtmod

 This is a standard CentOS 5.4 x86_64 install, and I have not been able to
 find a solution on the web.

Do you have the libvirt-python package installed?
Also check for the virt-viewer package (which helps with a lot of virt
tool errors).
