First up, give this section a read. It will explain what fencing does
and why you're seeing what you are;
https://alteeve.ca/w/2-Node_Red_Hat_KVM_Cluster_Tutorial#Concept.3B_Fencing
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.
[root@hitesh12 ~]# cat /etc/cluster/cluster.conf

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.
