The B<virsh> program is the main interface for managing virsh guest
|
||||
domains. The program can be used to create, pause, and shutdown
|
||||
domains. It can also be used to list current domains. Libvirt is a C toolkit to interract with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

The basic structure of every virsh command is almost always:
|
||||
The basic structure of most virsh usage is:
|
||||
|
||||
virsh <subcommand> <domain-id> [OPTIONS]
|
||||
virsh <command> <domain-id> [OPTIONS]
|
||||
|
||||
Where I<subcommand> is one of the sub commands listed below, I<domain-id>
|
||||
Where I<command> is one of the commands listed below, I<domain-id>
|
||||
is the numeric domain id, or the domain name (which will be internally
|
||||
translated to domain id), and I<OPTIONS> are sub command specific
|
||||
translated to domain id), and I<OPTIONS> are command specific
|
||||
options. There are a few exceptions to this rule in the cases where
|
||||
the sub command in question acts on all domains, the entire machine,

the command in question acts on all domains, the entire machine,
|
||||
or directly on the xen hypervisor. Those exceptions will be clear for
|
||||
each of those sub commands.
|
||||
each of those commands.
|
||||
|
||||
The B<virsh> program can be used either to run one command at a time
|
||||
by giving the command as an argument on the command line, or as a shell
|
||||
if no command is given in the command line, it will then start a minimal
|
||||
interpreter waiting for your commands and the B<quit> command will then exit
|
||||
the program.
|
||||
|
||||
=head1 NOTES
|
||||
|
||||
All B<virsh> opperations rely upon the libvirt library.
|
||||
For any virsh commands to run xend/qemu, or what ever virtual library that libvirt suports. For this reason you should start xend/qemu as a service when your system first boots using xen/qemu.
|
||||
All B<virsh> operations rely upon the libvirt library.
|
||||
For any virsh commands to run xend/qemu, or what ever virtual library that libvirt suports. For this reason you should start xend/qemu as a service when your system first boots using xen/qemu. This can usually be done using the command
|
||||
B<service start libvirtd> .
|
||||
|
||||
Most B<virsh> commands require root privledges to run due to the
|
||||
communications channels used to talk to the hypervisor. Running as
|
||||
non root will return an error.
|
||||
|
||||
Most B<virsh> commands act asynchronously, so just because the B<virsh>
|
||||
command returned, doesn't mean the action is complete. This is
|
||||
program returned, doesn't mean the action is complete. This is
|
||||
important, as many operations on domains, like create and shutdown,
|
||||
can take considerable time (30 seconds or more) to bring the machine
|
||||
into a fully compliant state. If you want to know when one of these
|
||||
actions has finished you must poll through virsh list periodically.

The \fBvirsh\fR program is the main interface for managing virsh guest
|
||||
domains. The program can be used to create, suspend, resume, save, and shutdown
|
||||
domains. It can also be used to list current domains. Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the \s-1GNU\s0 Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C \s-1API\s0 initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

The basic structure of every virsh command is almost always:
|
||||
The basic structure of most virsh usage is:
|

.PP

.Vb 1

|
||||
\& virsh <command> <domain-id> [OPTIONS]

Where \fIsubcommand\fR is one of the sub commands listed below, \fIdomain-id\fR
|

Where \fIcommand\fR is one of the commands listed below, \fIdomain-id\fR

translated to domain id), and \fI\s-1OPTIONS\s0\fR are sub command specific
|
||||
translated to domain id), and \fI\s-1OPTIONS\s0\fR are command specific
|
||||
options. There are a few exceptions to this rule in the cases where
|

the sub command in question acts on all domains, the entire machine,
|
||||
or directly on the xen hypervisor. Those exceptions will be explained for
|
||||
each of those sub commands.
|

the command in question acts on all domains, the entire machine,

each of those commands.
|

.PP
|
||||
The \fBvirsh\fR program can be used either to run one command at a time
|
||||
by giving the command as an argument on the command line, or as a shell
|
||||
if no command is given in the command line, it will then start a minimal
|
||||
interpreter waiting for your commands and the \fBquit\fR command will then exit
|
||||
the program.
|
||||
.SH "NOTES"
|
||||
.IX Header "NOTES"
|
||||
All \fBvirsh\fR operations rely upon the libvirt library.
|
||||
So any virsh commands may require to run xend or qemu (or which ever virtualization layer that libvirt will use). For this reason you should start xend or qemu as a service when your system first boots.
|
||||
For any virsh commands to run xend/qemu, or what ever virtual library that libvirt suports. For this reason you should start xend/qemu as a service when your system first boots using xen/qemu. This can usually be done using the command
|
||||
\&\fBservice start libvirtd\fR .
|
||||
.PP
|
||||
Most \fBvirsh\fR commands require root privledges to run due to the
|
||||
communications channels used to talk to the hypervisor. Running as
|
||||
non root will return an error.
|
||||
.PP
|
||||
Most \fBvirsh\fR commands act asynchronously, so just because the \fBvirsh\fR
|
||||
command returned, doesn't mean the action is complete. This is
|
||||
program returned, doesn't mean the action is complete. This is
|
||||
important, as many operations on domains, like create and shutdown,
|
||||
can take considerable time (30 seconds or more) to bring the machine
|
||||
into a fully compliant state. If you want to know when one of these
|
||||
actions has finished you must poll through virsh list periodically.
|
||||

|
||||
\&\fItype\fR can be either \fInetwork\fR to indicate a physical network device or \fIbridge\fR to indicate a bridge to a device.
|
||||
\&\fIsource\fR indicates the source device.
|
||||
\&\fItarget\fR allows to indicate the target device in the guest.
|
||||
\&\fImac\fR allows to specify the \s-1MAC\s0 address of the network interface.

|
||||
as command \fBattach-device\fR.
|
||||
.IP "\fBdetach-disk\fR \fIdomain-id\fR \fItarget\fR" 4
|
||||
.IX Item "detach-disk domain-id target"
|
||||

.SH "VIRTUAL NETWORKS COMMANDS"
|
||||
.IX Header "VIRTUAL NETWORKS COMMANDS"
|
||||
The following commands manipulate networks. Libvirt has the capability to
|
||||
define virtual networks which can then be used by domains and linked to
|
||||
actual network dvices. For more detailed informations about this feature
|
||||
see the documentation at <http://libvirt.org/format.html#Net1> . A lot
|
||||
of the command for virtual networks are similar to the one used for domains,
|
||||
but the way to name a virtual network is either by its name or \s-1UUID\s0.
|
||||
.IP "\fBnet-autostart\fR \fInetwork\fR optional \fI\-\-disable\fR" 4
|
||||
.IX Item "net-autostart network optional --disable"

|
||||
a description of the \s-1XML\s0 network format used by libvirt.
|
||||
.IP "\fBnet-define\fR \fIfile\fR" 4
|
||||

|
||||
.IX Item "net-dumpxml network"
|
||||
Output the virtual network information as an \s-1XML\s0 dump to stdout.

||||
.IX Item "net-list optional --inactive or --all"
|
||||
Returns the list of active networks, if \fI\-\-all\fR is specified this will also
|
||||
include defined but inactive networks, if \fI\-\-inactive\fR is specified only the
|
||||
inactive ones will be listed.
