systemd-detect-virt \- Detect execution in a virtualized environment

.SH "DESCRIPTION"
|
|
.PP
|
|
\fBsystemd\-detect\-virt\fR
|
|
detects execution in a virtualized environment\&. It identifies the virtualization technology and can distinguish full VM virtualization from container virtualization\&.
|
|
.PP
|
|
When executed without
|
|
\fB\-\-quiet\fR
|
|
will print a short identifier for the detected virtualization technology\&. The following technologies are currently identified:
|
|
\fIqemu\fR,
|
|
\fIkvm\fR,
|
|
\fIvmware\fR,
|
|
\fImicrosoft\fR,

\fIlxc\fR,

\fIlxc\-libvirt\fR,
|
|
\fIsystemd\-nspawn\fR\&.
|
|
.PP
|
|
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
|
|
\fB\-\-vm\fR
|
|
is passed)\&.
|
|
.SH "OPTIONS"
|

.PP
|
|
The following options are understood:
|
|
.PP
|
|
\fB\-c\fR, \fB\-\-container\fR
|
|
.RS 4
|
|
Only detects container virtualization (i\&.e\&. shared kernel virtualization)\&.
|
|
.RE
|
|
.PP
|
|
\fB\-v\fR, \fB\-\-vm\fR
|

.RS 4

Only detects VM virtualization (i\&.e\&. full hardware virtualization)\&.
|
|
.RE
|
|
.PP
|
|
\fB\-q\fR, \fB\-\-quiet\fR
|
|
.RS 4
|

Suppress output of the virtualization technology identifier\&.
|

.RE
|
|
.PP
|
|
\fB\-h\fR, \fB\-\-help\fR
|

.RS 4

Print a short help text and exit\&.
|

.RE
|

.PP
|

\fB\-\-version\fR
|

.RS 4
|

Print a short version string and exit\&.

.SH "EXIT STATUS"

.PP
|

If a virtualization technology is detected, 0 is returned, a non\-zero code otherwise\&.
