Have you ever wondered if the server you bought at the hosting provider is in fact a dedicated server or just a VPS and what is the underlying virtualization environment your server runs on?
virt-what provides us the ability to detect if we are running in a virtual machine or on bare-metal (real hrdware). virt-what detects common types of virtualization: hyperv, kvm, openvz, qemu, virtualbox, vmware, xen, etc…
Install virt-what (RedHat/CentOS/Fedora):
[root@tuxfixer ~]# yum install virt-what
Detect underlying environment:
[root@tuxfixer ~]# virt-what vmware
Note: If nothing is printed and the script exits with code 0 (no error), then it can mean either that the program is running on bare-metal or the program is running inside a type of virtual machine which we don’t know about or can’t detect.
