PV, though for the latest CentOS install it was easiest to create an HVM
install, boot and install the standard ISO via vnc/ssh and then just switch
to PV and reboot. Keep a copy of any given OS install and clone as needed

I confess I just treat the xen box as if it was 9 servers in a rack with a
gateway box, so I almost never see the interface - if I want to reboot a VM
I just mosh into it and type reboot :)

I keep a reference cfg file for PV and one for HVM installs, one directory
full of live cfg files and another full of disk images, all named sanely
(for me :) and about the only commands I use are 'xl list', 'xl top', 'xl
create <file>' and 'xl console'
