Xen and KVM are types of hypervisors, like virtualbox is, but they run
on Linux hosts. To use them, you would need to install linux on the bare
machine. This in turn requires a CPU that supports virtualization (which
most CPUs made in the last few years do support).
If you can install CentOS 6, you can use KVM which is what I recommend.

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

Hello,
I am not aware of fencing.Yes you are correct i have not
configured
anything related to fencing.
Can you please let me know as how can i proceed...Do i have
to purchase
some sort of hardware?
How can i implement Power Fencing?
I am using virtual box machines on my desktop in which linux are
installed and have been connected through swtich.

Hence they may not have IPMI/ILO etc.
I am 99.99% certain that fencing has not been configured.
I also doubt if it has external storage.
(I can identify as I tried my experiments with clusters
first time
with such desktop class machines)
The only solution for this is Power Fencing.
