SYSTEMD-DETECT-VIR(1)systemd-detect-virtSYSTEMD-DETECT-VIR(1)NAMEsystemd-detect-virt - Detect execution in a virtualized environment
SYNOPSISsystemd-detect-virt [OPTIONS...]
DESCRIPTIONsystemd-detect-virt detects execution in a virtualized environment. It
identifies the virtualization technology and can distuingish 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, 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.
