is nice but now I want to have a resource to start and stop vserver ? Does anyone know
how to do that ? I've found several script with google for heartbeat but doesn't work
so much ... especially with the meta part.

I wrote myself one a few months ago. Recently I discovered ocf-tester,
so I took the opportunity and corrected the failed tests and here it is,
the ocf-tester-approved and hopefully still working
/usr/lib/ocf/resource.d/lihas/VServer-lihas
