I downloaded and installed Citrix xenserver.
I am trying to get a centos 5.3 guest working. I have installed it using a pxe kickstart and the "Install other media" template. It is up and running but I believe it is not paravirtualized. The disk device is listed as /dev/hda and it is performing at a 6th of the io rate that my centos 5.2 template is. The 5.2 template has /dev/xvda as its root device. How move from the hda device to xda device in 5.3? I guess what im really asking is how to I paravirtualize a host that is not already paravirtualized. I have also installed the xen kernel in the 5.3 machine and still no luck.
