Xen users - Sep 2008 - kernel.sysrq, does it work for Xen

Has anyone successfully set kernel.sysrq = 1
on a Xen kernel either in dom0 or in domU?  Does it do
what is intended, i.e. allow the machine to be reset?
In the case of domU, is there a way to send the Sysrq character
across the xen console that is accessed via xm cons?

(This is Xen 3.1.0 that I am using at the moment).

Thanks

Steve Timm

# xm sysrq
Error: ''xm sysrq'' requires 2 arguments.

Usage: xm sysrq <Domain> <letter>

Send a sysrq to a domain.
