• autostart - Configures a KVM domain to start when the host boots.

• console - Connect to the virtual serial console of a host.

• create - Create a domain from an XML configuration file and start it.

• define - Create a domain from an XML configuration file, but do not start it.

• undefine - Undefine a domain. If the domain is inactive, the domain configuration is removed.

• edit - Edit the XML configuration file for a doma in, which will affect the next boot of the guest.

• reboot - Reboot the domain, as if the reboot command had been run from inside the guest.

• shutdown - Gracefully shuts down the domain, as if the shutdown command had been run from inside the guest.

• screenshot - Takes a screens hot of a current domain console and stores it in a file.
