I think you're out of luck - you either need the root password or physical 
access.  The one thing you can try is the Magic SysRq key - SysRq + o = reboot, 
so if the KVM has the capability of sending keyboard macros, you could try this 
key combo for a hard reboot and see if that works.  I don't know off the top of 
my head if XCP supports SysRq out of the box - some systems support limited 
features, like halt/reboot, others have it completely disabled, and then some 
have all of the SysRq keys enabled.
