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.
