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: ID VM Product qemu QEMU software virtualization kvm Linux KVM kernel virtual machine vmware VMware Workstation or Server, and related products microsoft Hyper-V, also known as Viridian or Windows Server Virtualization oracle Oracle VM VirtualBox (historically marketed by innotek and Sun Microsystems) xen Xen hypervisor bochs Bochs Emulator uml User-mode Linux ID Container Product openvz OpenVZ/Virtuozzo lxc Linux container implementation by LXC lxc-libvirt Linux container implementation by libvirt systemd-nspawn systemd's minimal container implementation, see systemd-nspawn1 docker Docker container manager 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). 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. If a virtualization technology is detected, 0 is returned, a non-zero code otherwise. systemd1, systemd-nspawn1
