Novell LINUX ENTERPRISE SERVER 10 SP2 - VIRTUALIZATION WITH XEN Manual page 38

list the current domains, enable or pin virtual CPUs, and attach or detach block devices.
For example, the xm list command displays the status of all virtual machines.
# xm list
Name
Domain-0
OES
SLES10
The syntax of the xm command usually follows the format:
xm <subcommand> [domain-id] [OPTIONS]
where subcommand is the xm command to run, domain-id is the ID number assigned
to a domain or the name of the virtual machine, and OPTIONS indicates subcommand-
specific options.
Other useful xm commands include:
• xm start starts a virtual machine
• xm reboot reboots a virtual machine
• xm destroy immediately terminates a virtual machine
• xm block-list displays all virtual block devices attached to a virtual machine
• All xm operations require that the Xen control daemon, xend, be running. For this
reason, you should make sure xend starts whenever the host boots.
• Most xm commands require root privileges to allow interaction with the Xen hyper-
visor. Entering the xm command when you are not logged in as root returns an error.
• Some xm commands return no information even though the action is completed.
In some instances, for example, when shutting down a virtual machine, the action
can take several seconds to complete. To verify that the action has completed, you
might need to view its status another way, such as, using the xm list command.
For a complete list of xm command parameters, enter xm help at the command line
or read the manual page of xm.
