Hi All, Has anyone succesfully been able to run a CentOS 4.4 (or 4.3) in FC6 ? It runs fine in old FC5 (July 2006) but I cannot somehow get it to access the root file system, see the details: [root@louisxi xen]# xm create -c spooner Using config file "spooner".

If I have to re create an initrd, can you please provide the steps ? Thank you for your advise. -- Frank Morane (Free Thinker)
