I just installed Centos 5.5 with the xen kernel on an older machine. It has Xeon processors and a 700 Mhz processor speed, so I realize I must use para-virtualized guests. Reading the Centos/RH Virtualization Guide gives examples of the process of installing guest hosts, but it only lists installing Windows as a fully-virtualized host. Is that because they only showed those types of examples or is it that Windows hosts can't be para-virtualized? Secondly, what's the normal what to install a Centos guest when it comes to defining the installation media (it lists HTTP, FTP, or NFS). This machine only has a CD drive, so I'm a little confused about the best way to handle this since the Centos installation now consists of 6 CDs. A brief explanation would be handy. Thanks for any help and time offered. I'm sure there'll be more questions later. Steve Campbell
