All working a treat: created the guest (fully virtualised - I have no time for Xen), setup disk space in a 6Gb file, gave it a name, and pointed the installation source to be the first of 6 .iso files for Centos 5 installation ......then it asks for the second CDRom! How the blazes is one supposed to tell it where to get the file? I'm completely stuck! I thought this was supposed to work with .iso files and I wouldn't have to burn 6 CDs. But what happens now?
