Today on freshmeat I noticed 2 useful utilities for anyone running Xen Servers.
The first is called Virt-top it is a easier to read top like tool than xm top that shows all virtual machines memory and CPU usage in a nice display including totals etc:

The other – Virt-P2V – it’s a CD Image that you can boot a physical machine with that will then convert it to a virtual machine for you. It will scp the drive image to a destination of your choice and create a config file to boot it after asking you some questions. I intend to use this to move a VMWare virtual machine to Xen soon, will post here and see how it goes.
Both of these come from a Red Hat employee, with some luck we’ll see these included in Red Hat Linux soon.
