Xen users - Feb 2010 - XCP 0.1.1 as redhat cluster fence device for domUs

Hi,

I plan to run a few ha services on some DomUs coordinated by a redhat 
cluster infrastructure, but fault tolerance would require a method to 
fence the failing DomUs, I was thinking of a daemon running  in Dom0 and 
executing hard_reboot_vm  against the DomU to be fenced. The DomU which 
would fence the other would connect to this daemon and after some kind 
of challenge-response auth would give the name (or uuid) of the DomU to 
be fenced. I''ve started to prototype this in python.
Please let me know if there is anything I my have overlooked.

Thanks

Geza
