Thankyou very much for your detailed instructions.

I'm stuck with this error
Error: No Groups on which to run command

And my xen-yum.conf lokk like this.

[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
exclude=*-debuginfo
gpgcheck=0
obsoletes=1
reposdir=/dev/null

[base]
name=CentOS-4.5 - Plus
baseurl=http://mirror.centos.org/centos/4.5/centosplus/i386/ enabled=1

Where do you think I'm going wrong?

Thanks.
Chris.
