Comment 12 for bug 993010

I think ideally it should work for both, but it might be necessary to *build* the EL5 images from an EL6 host. The process I'm looking at is somewhat similar to that described in the link below but using virt-install and a kickstart file to apply customizations and then using virt-sysprep (from libguestfs-tools) to edit the image scrubbing mac addresses etc:

I'm a little bit worried I'm reinventing the wheel here so if anyone has gotten further along with this feel free to pipe up!
