NAME
       systemd-detect-virt - Detect execution in a virtualized environment

SYNOPSIS
       systemd-detect-virt [OPTIONS...]

DESCRIPTION
       systemd-detect-virt detects execution in a virtualized environment. It identifies the
       virtualization technology and can distinguish full VM virtualization from container
       virtualization.

       When executed without --quiet will print a short identifier for the detected
       virtualization technology. The following technologies are currently identified: qemu, kvm,
       vmware, microsoft, oracle, xen, bochs, chroot, uml, openvz, lxc, lxc-libvirt,
       systemd-nspawn.

       If multiple virtualization solutions are used, only the "innermost" is detected and
       identified. That means if both VM virtualization and container virtualization are used in
       conjunction, only the latter will be identified (unless --vm is passed).

OPTIONS
       The following options are understood:

       -h, --help
	   Prints a short help text and exits.

       --version
	   Prints a short version string and exits.

       -c, --container
	   Only detects container virtualization (i.e. shared kernel virtualization).

       -v, --vm
	   Only detects VM virtualization (i.e. full hardware virtualization).

       -q, --quiet
	   Suppress output of the virtualization technology identifier.

EXIT STATUS
       If a virtualization technology is detected, 0 is returned, a non-zero code otherwise.
