["James Song" <jsong@xxxxxxxxxx>]

This patch adds a new option "description = " to each VM to increase the manageability of VM, which could be accessed via "xm list -l MACHINE".e.g add "description='(name, james),(priority 5), (owner james.song@xxxxxxxxxxx)' " to configure file, User can get the VM's attribute easily by "xm list -l Machine" or some tools.
