bochs - Portable x86 Emulator. SYNOPSIS
bochs [bochs_options] [bochsrc_options] DESCRIPTION
Bochs is a portable Intel Architecture 32 (x86) emulator that runs on most popular operating systems. Inside the emulator, it can run many operating systems including Linux and Microsoft(R) Windows(R). OPTIONS
When you run bochs without one of the following options, it will search for a configuration file called .bochsrc in the current directory and your home directory and display the start menu. -q With this option the start menu will be skipped after loading the configuration file. -f configfile This option specifies the name of the configuration file. -qf configfile When you run bochs with this option, it will skip the start menu and use the specified configuration file. -n With this option bochs doesn't load a configuration file. In that case the setup for the emulation must be done with bochsrc options on the command line or in the start menu. -h, --help Print a summary of the command line options for bochs and exit. You can override the settings from the configuration file with command line arguments, using the same syntax as the bochsrc file. If you have any spaces in your command line arguments, they should be enclosed in single quotes. For information on Bochs command line and configuration file arguments, see the man page bochsrc(5). Example: bochs -q 'boot:a' 'floppya: 1_44=a.img, status=inserted' LICENSE

SYSTEMD-DETECT-VIRT(1) systemd-detect-virt SYSTEMD-DETECT-VIRT(1) 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 machine virtualization from container virtualization. systemd-detect-virt exits with a return value of 0 (success) if a virtualization technology is detected, and non-zero (error) otherwise. By default, any type of virtualization is detected, and the options --container and --vm can be used to limit what types of virtualization are detected. When executed without --quiet will print a short identifier for the detected virtualization technology. The following technologies are currently identified: Table 1. Known virtualization technologies (both VM, i.e. full hardware virtualization, and container, i.e. shared kernel virtualization) +----------+----------------+--------------------------------------+ |Type | ID | Product | +----------+----------------+--------------------------------------+ |VM | qemu | QEMU software virtualization, | | | | without KVM | | +----------------+--------------------------------------+ | | kvm | Linux KVM kernel virtual machine, | | | | with whatever software, except | | | | Oracle Virtualbox | | +----------------+--------------------------------------+ | | zvm | s390 z/VM | | +----------------+--------------------------------------+ | | 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), | | | | for legacy and KVM | | | | hypervisor | | +----------------+--------------------------------------+ | | xen | Xen hypervisor (only domU, not dom0) | | +----------------+--------------------------------------+ | | bochs | Bochs Emulator | | +----------------+--------------------------------------+ | | uml | User-mode Linux | | +----------------+--------------------------------------+ | | parallels | Parallels Desktop, Parallels Server | | +----------------+--------------------------------------+ | | bhyve | bhyve, FreeBSD hypervisor | +----------+----------------+--------------------------------------+ |Container | 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- | | | | nspawn(1) | | +----------------+--------------------------------------+ | | docker | Docker container manager | | +----------------+--------------------------------------+ | | rkt | rkt app container runtime | +----------+----------------+--------------------------------------+ If multiple virtualization solutions are used, only the "innermost" is detected and identified. That means if both machine 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 hardware virtualization). -r, --chroot Detect whether invoked in a chroot(2) environment. In this mode, no output is written, but the return value indicates whether the process was invoked in a chroot() environment or not. --private-users Detect whether invoked in a user namespace. In this mode, no output is written, but the return value indicates whether the process was invoked inside of a user namespace or not. See user_namespaces(7) for more information. -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. SEE ALSO
