4.2.1 Basic Management Commands

One useful command is # xm list which lists all domains running in rows of the following format:

name domid memory vcpus state cputime

The meaning of each field is as follows:

name
The descriptive name of the virtual machine.
domid
The number of the domain ID this virtual machine is running in.
memory
Memory size in megabytes.
vcpus
The number of virtual CPUs this domain has.
state
Domain state consists of 5 fields:
r
running
b
blocked
p
paused
s
shutdown
c
crashed
cputime
How much CPU time (in seconds) the domain has used so far.

The xm list command also supports a long output format when the -l switch is used. This outputs the full details of the running domains in xend's SXP configuration format.

You can get access to the console of a particular domain using the # xm console command (e.g. # xm console myVM).
