systemd-detect-virt
Detect virtualization environment
TLDR
List detectable virtualization technologies
$ systemd-detect-virt --list
Detect virtualization and print the result$ systemd-detect-virt
Silently check without printing anything$ systemd-detect-virt -q
Only detect container virtualization$ systemd-detect-virt -c
Only detect hardware virtualization$ systemd-detect-virt -v
Detect whether in a chroot environment$ systemd-detect-virt -r
SYNOPSIS
systemd-detect-virt [options]
DESCRIPTION
systemd-detect-virt detects whether the system is running in a virtualized environment and prints the detected virtualization technology. It returns exit code 0 if virtualization is detected, non-zero otherwise.
Detectable technologies include: KVM, QEMU, VMware, VirtualBox, Xen, Hyper-V, Docker, LXC, systemd-nspawn, and many others. The --list option shows all supported technologies.
PARAMETERS
--list
List all detectable virtualization technologies-q, --quiet
Suppress output, only return exit code-c, --container
Only detect container virtualization-v, --vm
Only detect hardware VM virtualization-r, --chroot
Detect chroot environment--private-users
Detect user namespace
CAVEATS
Detection relies on various heuristics and may not detect all virtualization types. Some nested virtualization scenarios may report only the innermost layer. Part of the systemd suite.
