Hi,
I think Domain0 should NOT stop by virsh domain stop commands.
(like shutdown, reboot, destroy).
But virsh shudown and reboot commands are still available for Dom0.
This patch intends to disable these two commands for Dom0.
Internal processing of these two commands is following
1)Send shutdown or reboot to Xend (Guard of xend)
2)If 1) is failed, shutdown/reboot is executed by xenstore. (Not Guard)
This patch removes 2) ,that is as same as destroy processing.

The problem with that patch it that is also remove the possibility of
falling back to the XenStore methode for other domains than Dommain0 .
So IMHO that's too radical, could you rather make a patch which add the check
in xenStoreDomainShutdown and xenStoreDomainReboot for domain 0 instead ?
thanks,

Sounds good (I would just fully parenthesize the boolean expressions)
I can't apply it myself at the moment, but I guess Dan or Mark can do it :-)
thanks !
