Bug 189097

Description of problem:
Running xenguest-install to install a guest using this command:

/usr/sbin/xenguest-install.py -n deon -f /home/admin/deon/deon.xen -r 256 -l
http://www.wurley.vpn/yum/Fedora/5/

fails with:
 raise Errors.RepoError, saved_repo_error, 
RepoError: failure: 
Fedora/RPMS/gjdoc-0.7.7-3.1.i386.rpm from
anaconda: [Errno 256] No more mirrors to try.

How reproducible:
Every time.

Steps to Reproduce:
1. Run installation, unselect all components (for a minimal install), fails
almost immediately when going to install packages.
  
Additional info:
My HTTP FC5 repository works fine for running systems with YUM - I used it to
upgrade from FC5test3 to FC5, and use it on other FC5 servers...

It looks like this:
lrwxrwxrwx 1 root root      24 Apr 16 12:29 disc1 -> /mnt/iso/FC-5-i386-disc1
lrwxrwxrwx 1 root root      24 Apr 16 12:29 disc2 -> /mnt/iso/FC-5-i386-disc2

drwxr-xr-x 2 root root     904 Mar  1 00:55 RPMS.extras

With the ISO's automounted as required (this does work - I use "yum install" on
other systems all the time)

It seems that the installation wants to install gjdoc using this URL (taken from
the apache log):
disc1/Fedora/RPMS/gjdoc-0.7.7-3.1.i386.rpm, whereas the jgodc package is on
disc2? I dont understand how it could think it was on disc1, when createrepo
would have it listed on disc2?

I've re-run createrepo before starting the install just to be sure it was up to
date. (I've also confirmed looking that the createrepo files, that it has
location href=disc2...)
