Identify Server is Virtual Machine OR Physical Machine

   There is no hard and fast rule to check whether the machine is physical or virtual but still we do have some commands which can be used for the some purpose.

NOTE: There might be other commands as well but these are the few of my knowledge.

Physical Servers

   If your machine is physical then it will show you the output as Hardware manufacture name. 

 ~]# dmidecode -s system-manufacturer



 ~]# dmidecode -s system-product-name





~]# dmidecode |grep Manufacturer

Virtual Servers

Run below commands to identify Virtual Machine.

~]#dmidcode |grep -i vmware

~]#lspci |grep -i vmware

~]#dmidcode -s system-product-name

 If you have more commands to identify Physical / Virtual Machine Please comment.
