Re: [Xen-users] centos4.5(domU) on etch(dom0)

["Chris Fanning" <christopher.fanning@xxxxxxxxx>]

Hi,

Just to add some more information so you might be able to know better
where I'm going wrong.

I added the file /etc/yum.repos.d/CentOS-Base.repo
and pasted this
http://ruckman.net/tech/wp-content/uploads/2007/05/centos-baserepo.txt
into it. and changed all 4's for 4.5's (I need centos4.5).

Then I did a
# yum --enablerepo=centosplus
There was lots of net traffic and all seemed well.

But.
yum -c yum.conf --installroot=/mnt/ -y groupinstall Base
Warning, could not load sqlite, falling back to pickle
Setting up Group Process
Setting up repositories
not using ftp, http[s], or file for repos, skipping - enabled=1
base                      100% |=========================|  951 B    00:00
Error: No Groups on which to run command

Thanks again. (I hope this isn't turning into an off-topic)
Chris.
