Please find out what's your python searching path first.
For example, in my Fedora Core 2 box,

[root@richardz xen-unstable-install]# python
Python 2.3.3 (#1, May  7 2004, 10:31:40)
[GCC 3.3.3 20040412 (Red Hat Linux 3.3.3-7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/usr/lib/python2.3', '/usr/lib/python23.zip', 
'/usr/lib/python2.3/plat-linux2', '/usr/lib/python2.3/lib-tk', 
'/usr/lib/python2.3/lib-dynload', '/usr/lib/python2.3/site-packages', 
'/usr/lib/python2.3/site-packages/gtk-2.0']
>>>

You can see my python version is 2.3.3, and the library searching path 
contains /usr/lib/python2.3.
FYI, xend and xm, etc , are tools written in python, and after 
installation, the library files which is required by xend should be 
copied to the python's library searching path.
Again in my box,
Source:
[root@richardz Xen3]# ls ./xen-unstable-install/install/usr/lib/python/xen
__init__.py  __init__.pyc  lowlevel  sv  util  web  xend  xm
[root@richardz Xen3]#
Destination:
[root@richardz Xen3]# ls /usr/lib/python2.3/site-packages/xen
__init__.py  __init__.pyc  lowlevel  sv  util  web  xend  xm
[root@richardz Xen3]#

If the xen directory is not in the right place, you can copy it manually.

If I am wrong, anyone please correct me. Thanks.
