Autostart VM in Cockpit

List Available Virtual Machines

To start let’s list all available Virtual machines on our host system:

sudo virsh list --all
Id    Name                           State
----------------------------------------------------
-     server.linuxconfig.org            shut off

To check whether given virtual machine is already configured to start after host system’s boot run:

sudo virsh dominfo server.linuxconfig.org
Id:             -
Name:           server.linuxconfig.org
UUID:           df25d714-1c73-4b4a-b566-9d0a17295702
OS Type:        hvm
State:          shut off
CPU(s):         2
Max memory:     1048576 KiB
Used memory:    1048576 KiB
Persistent:     yes
Autostart:      disable
Managed save:   no
Security model: selinux
Security DOI:   0

Furthermore, to list all virtual machines already configured to autostart run:

sudo ls /etc/libvirt/qemu/autostart/

Enable Virtual Machine automatic start

To enable the above KVM virtual machine to start automatically run the following linux command:

sudo virsh autostart server.linuxconfig.org
Domain server.linuxconfig.org marked as autostarted

If virsh command is not available/installed, to configure austostart simply create a new symbolic link within /etc/libvirt/qemu/autostart/ directory using ln command. Example:

sudo ln -s /etc/libvirt/qemu/server.linuxconfig.org.xml /etc/libvirt/qemu/autostart/server.linuxconfig.org.xml

and reload hyper-visor if necessary:

sudo systemctl reload libvirtd

Confirm whether autostart is enabled:

sudo virsh dominfo server.linuxconfig.org
Id:             -
Name:           server.linuxconfig.org
UUID:           df25d714-1c73-4b4a-b566-9d0a17295702
OS Type:        hvm
State:          shut off
CPU(s):         2
Max memory:     1048576 KiB
Used memory:    1048576 KiB
Persistent:     yes
Autostart:      enable
Managed save:   no
Security model: selinux
Security DOI:   0

Disable Virtual Machine autostart

To disable virtual machine autostart execute:

sudo virsh autostart --disable server.linuxconfig.org
Domain server.linuxconfig.org unmarked as autostarted

or simply use unlink command to remove virtual machine’s symbolic link from /etc/libvirt/qemu/autostart/ directory:

sudo unlink /etc/libvirt/qemu/autostart/server.linuxconfig.org.xml
