== Managing Virtual Machines
|
|
|
|
When the installation of the guest operating system is complete, it can
|
|
be managed using the `virt-manager` program or via command line
|
|
using `virsh`.

|
=== Managing guests with virt-manager
|
|
|
|
. Start the Virtual Machine Manager by navigating to
|
|
menu:[Applications]System Tools, or run:
|
|
+
|
|
----
|
|
$ su -c "virt-manager"
|
|
----
|
|
+
|
|
If you are not root, you will be prompted to enter the root
|
|
password. Choose `Run unprivileged` to operate in read-only non-root
|
|
mode.
|
|
+
|
|
. Choose the host you wish to manage and click *Connect* in the "Open
|
|
Connection" dialog window.
|
|
. The list of virtual machines is displayed in the main window. Guests
|
|
that are running will display a ">" icon. Guests that are not running
|
|
will be greyed out.
|
|
. To manage a particular guest, double click on it, or right click and
|
|
select "Open".
|
|
. A new window for the guest will open that will allow you to use its
|
|
console, see information about its virtual hardware and start, stop, and pause
|
|
it.
|
|
|

[[managing-guests-with-virsh]]
|
|
=== Managing guests with virsh
|
|
|
|
The `virsh` command line utility allows you to manage virtual
|
|
machines on the command line. The `virsh` utility is built around the libvirt management API:
|
|
|
|
* `virsh` has a stable set of commands whose syntax and semantics are
|
|
preserved across updates to the underlying virtualization platform.
|
|
* `virsh` can be used as an unprivileged user for read-only operations
|
|
(e.g. listing domains, listing domain statistics).
|
|
* `virsh` can manage domains running under Xen, QEMU/KVM, ESX or other
|
|
back-ends with no perceptible difference to the user.
|
|
|
|
To start a virtual machine:
|
|
+
|
|
----
|
|
$ su -c "virsh create <name of virtual machine>"
|
|
----
|
|
|
|
|
|
To list the virtual machines currently running:
|
|
+
|
|
----
|
|
$ su -c "virsh list"
|
|
----
|
|
|
|
To list all virtual machines, running or not:
|
|
+
|
|
----
|
|
$ su -c "virsh list --all"
|
|
----
|
|
|
|
To gracefully power off a guest:
|
|
+
|
|
----
|
|
$ su -c "virsh shutdown <virtual machine (name | id | uuid)>"
|
|
----
|
|
|
|
To non gracefully power off a guest:
|
|
+
|
|
----
|
|
$ su -c "virsh destroy <virtual machine (name | id | uuid)>"
|
|
----
|
|
|
|
To save a snapshot of the machine to a file:
|
|
+
|
|
----
|
|
$ su -c "virsh save <virtual machine (name | id | uuid)> <filename>"
|
|
----
|
|
|
|
To restore a previously saved snapshot:
|
|
+
|
|
----
|
|
$ su -c "virsh restore <filename>"
|
|
----
|
|
|
|
To export the configuration file of a virtual machine:
|
|
+
|
|
----
|
|
$ su -c "virsh dumpxml <virtual machine (name | id | uuid)"
|
|
----
|
|
|
|
For a complete list of commands available for use with `virsh`:
|
|
+
|
|
----
|
|
$ su -c "virsh help"
|
|
----
|
|
|
|
Or consult the manual page: `man virsh`
|
|
|
|
Bugs in the `virsh` tool should be reported in
|
|
http://bugzilla.redhat.com[Bugzilla] against the `libvirt` component.

[[remote-management]]
|
|
=== Remote management
|
|
|
|
The following remote management options are available:
|
|
|
|
* If using non-root users via SSH, see the setup instructions in http://wiki.libvirt.org/page/SSHSetup
|
|
* If using root for access via SSH, then create SSH keys for root, and
|
|
use `ssh-agent` and `ssh-add` before launching `virt-manager`.
|
|
* To use TLS, set up a local certificate authority and issue x509 certs
|
|
to all servers and clients. For information on configuring this option,
|
|
see http://wiki.libvirt.org/page/TLSSetup.
