Centos 5 Server Error

[Chromer]

After attempting to install on a Centos 5 server for the fist time I keep running across the following error:

[root@server ~]# virt-manager
Traceback (most recent call last):
File "/usr/share/virt-manager/virt-manager.py", line 304, in ?main()
File "/usr/share/virt-manager/virt-manager.py", line 224, in mainimport gtk
File "/usr/lib/python2.4/site-packages/gtk-2.0/gtk/__init__.py", line 76, in ?_init()
File "/usr/lib/python2.4/site-packages/gtk-2.0/gtk/__init__.py", line 64, in _init_gtk.init_check()
RuntimeError: could not open display

I would appreciate any help with this problem.

Thanks for the info. Is there any benefit or drawback to using 64-bit CentOS over 32-bit? The hardware supports 64-bit and I did check to be sure that 64-bit CentOS is supported by the software.
