Problem with Xen instalation

[klaus_19w74]

Hello,

I just installed Xen in a 64bits RHEL 5.4, however every time I'm getting this error every time:

Traceback (most recent call last):
File "/usr/sbin/xm", line 8, in ?
from xen.xm import main
File "/usr/lib/python2.4/site-packages/xen/xm/main.py", line 54, in ?
from xen.util.acmpolicy import ACM_LABEL_UNLABELED_DISPLAY
File "/usr/lib/python2.4/site-packages/xen/util/acmpolicy.py", line 30, in ?

from xen.lowlevel import acm
ImportError: /usr/lib/python2.4/site-packages/xen/lowlevel/acm.so: wrong ELF class: ELFCLASS32


# uname -r
2.6.18-274.el5xen

I've instaled:

python-virtinst-0.400.3-12.el5.noarch.rpm
libvirt-python-0.9.0-1.el5.art.x86_64.rpm
libvirt-0.9.0-1.el5.art.x86_64.rpm
kernel-xen-2.6.18-274.el5.x86_64.rpm


Have I done anything wrong?

Thanks,

Klaudio

Installing Xen on a 5.x system will install a new kernel. Perhaps that is the source of the problem? What happens if you select at boot time the previous (non-xen) kernel? I know that I was able to run Xen on my old CentOS 5.4 system, but then I installed it from scratch with Xen enabled. I removed it a little while later because I could not install the proprietary nVidia drivers in order to get the full 1920x1200 resolution from my HD monitors - nVidia did not support Xen kernels...
