First up, give this section a read. It will explain what fencing does 
and why you're seeing what you are;

As for being virtualbox guests, you're in a bit of a spot as there 
doesn't seem to be a native agent. Google shows this though;

If you can switch to KVM or Xen, then you can use the fence_virsh or 
fence_xvm agents.

cheers
