|
|
virt-admin - daemon administration interface
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<virt-admin> [I<OPTION>]... [I<COMMAND_STRING>]
|
|
|
|
B<virt-admin> [I<OPTION>]... I<COMMAND> [I<ARG>]...
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<virt-admin> program is the main administration interface for modifying
|
|
the libvirt daemon configuration at runtime, changing daemon behaviour as well
|
|
as for monitoring and managing all clients connected to the daemon.
|
|
|
|
The basic structure of most virt-admin usage is:
|
|
|
|
virt-admin [OPTION]... <command> [ARG]...
|
|
|
|
Where I<command> is one of the commands listed below.
|
|
|
|
The B<virt-admin> program can be used either to run one I<COMMAND> by giving the
|
|
command and its arguments on the shell command line, or a I<COMMAND_STRING>
|
|
which is a single shell argument consisting of multiple I<COMMAND> actions
|
|
and their arguments joined with whitespace, and separated by semicolons
|
|
between commands. Within I<COMMAND_STRING>, virt-admin understands the
|
|
same single, double, and backslash escapes as the shell, although you must
|
|
add another layer of shell escaping in creating the single shell argument.
|
|
If no command is given in the command line, B<virt-admin> will then start a minimal
|
|
interpreter waiting for your commands, and the B<quit> command will then exit
|
|
the program.
|
|
|
|
The B<virt-admin> program understands the following I<OPTIONS>.
|
|
|
|
=over 4
|
|
|
|
=item B<-c>, B<--connect> I<URI>
|
|
|
|
Connect to the specified I<URI>, as if by the B<connect> command,
|
|
instead of the default connection.
|
|
|
|
=item B<-d>, B<--debug> I<LEVEL>
|
|
|
|
Enable debug messages at integer I<LEVEL> and above. I<LEVEL> can
|
|
range from 0 to 4 (default). See the documentation of B<VIRT_ADMIN_DEBUG>
|
|
environment variable below for the description of each I<LEVEL>.
|
|
|
|
=item B<-h>, B<--help>
|
|
|
|
Ignore all other arguments, and behave as if the B<help> command were
|
|
given instead.
|
|
|
|
=item B<-l>, B<--log> I<FILE>
|
|
|
|
Output logging details to I<FILE>.
|
|
|
|
=item B<-q>, B<--quiet>
|
|
|
|
Avoid extra informational messages.
|
|
|
|
=item B<-v>, B<--version[=short]>
|
|
|
|
Ignore all other arguments, and prints the version of the libvirt library
|
|
virt-admin is coming from
|
|
|
|
=item B<-V>, B<--version=long>
|
|
|
|
Ignore all other arguments, and prints the version of the libvirt library
|
|
virt-admin is coming from.

|
|
=head1 NOTES
|
|
|
|
Running B<virt-admin> requires root privileges due to the
|
|
communications channels used to talk to the daemon. Consider changing the
|
|
I<unix_sock_group> ownership setting to grant access to specific set of users
|
|
or modifying I<unix_sock_rw_perms> permissions. Daemon configuration file
|
|
provides more information about setting permissions.
|
|
|
|
=head1 GENERIC COMMANDS
|
|
|
|
The following commands are generic.
|
|
|
|
=over 4
|
|
|
|
=item B<help> [I<command-or-group>]
|
|
|
|
This lists each of the virt-admin commands. When used without options, all
|
|
commands are listed, one per line, grouped into related categories,
|
|
displaying the keyword for each group.
|
|
|
|
To display detailed information for a specific command, use its name as the
|
|
option.
|
|
|
|
=item B<quit>, B<exit>
|
|
|
|
quit this interactive terminal
|
|
|
|
=item B<version>
|
|
|
|
Will print out the version info about which libvirt library was this client
|
|
built from. As opposed to I<virsh> client, the output already includes
|
|
the version of the daemon.
|
|
|
|
B<Example>
|
|
|
|
$ virt-admin version
|
|
Compiled against library: libvirt 1.2.21
|
|
Using library: libvirt 1.2.21
|
|
Running against daemon: 1.2.20
|
|
|
|
=item B<cd> [I<directory>]
|
|
|
|
Will change current directory to I<directory>. The default directory
|
|
for the B<cd> command is the home directory or, if there is no I<HOME>
|
|
variable in the environment, the root directory.
|
|
|
|
This command is only available in interactive mode.
|
|
|
|
=item B<pwd>
|
|
|
|
Will print the current directory.
|
|
|
|
=item B<connect> [I<URI>]
|
|
|
|
(Re)-Connect to a daemon's administrating server. The I<URI> parameter
|
|
specifies how to connect to the administrating server.
|
|
If I<LIBVIRT_ADMIN_DEFAULT_URI> or I<admin_uri_default> (see below) were set,
|
|
I<connect> is automatically issued every time a command that requires an
|
|
active connection is executed. Note that this only applies if there is no
|
|
connection at all or there is an inactive one.
|
|
|
|
To find the currently used URI, check the I<uri> command documented below.
|
|
|
|
For remote access see the documentation page at
|
|
L<http://libvirt.org/uri.html> on how to make URIs.
|
|
|
|
=item B<uri>
|
|
|
|
Prints the administrating server canonical URI, can be useful in shell mode. If
|
|
no I<uri> was specified, neither I<LIBVIRT_ADMIN_DEFAULT_URI> or
|
|
I<admin_uri_default> were set, libvirtd:///system is used.
