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:

-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.

-h, --help

Print a short help text and exit.

--version

Print a short version string and exit.

Exit status

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