Another method to find out if the OS is running in virtual environment

Fedora, Red Hat Enterprise Linux, and CentOS have a tool called 'virt-what' that detects if the operating system is running in a virtual environment.

It can detect the following environments:


hyperv: Microsoft Hyper-V hypervisor
ibm_systemz: IBM SystemZ (or other S/390)
ibm_systemz-direct: IBM SystemZ hardware partitioning system
ibm_systemz-lpar: LPAR on an IBM SystemZ hardware partitioning system
ibm_systemz-zvm: z/VM guest running in an LPAR on an IBM SystemZ hardware partitioning system
linux_vserver: Linux VServer container
kvm: KVM hypervisor using hardware acceleration
openvz: OpenVZ or Virtuozzo container
parallels: Parallels Virtual Platform (Parallels Desktop, Parallels Server)
powervm_lx86: IBM PowerVM Lx86 Linux/x86 emulator
qemu: QEMU hypervisor using software emulation
uml: User-Mode Linux (UML) guest
virt: Some sort of generic virtualization
virtage: Hitachi Virtualization Manager (HVM) Virtage hardware partitioning system
virtualbox: VirtualBox guest
virtualpc: Microsoft VirtualPC
vmware: VMware hypervisor
xen: Xen hypervisor
xen-dom0: Xen domU (paravirtualized guest domain)
xen-hvm: Xen guest fully virtualized (HVM)


To install it run:

yum install virt-what

Usage is as simple as running it without any options.
