This Chapter contains information on the Oracle VM Server domain lifecycle,
monitoring and administration. It contains:

Domain Lifecycle
■
Using the xm Command-Line Interface
You can use Oracle VM Manager to monitor domains running on Oracle VM Server, or
you can use the xm command. Using Oracle VM Manager is the recommended
method of managing domains. See the Oracle VM Manager User's Guide for information
on using Oracle VM Manager to manage domains (virtual machines).
5.1 Domain Lifecycle
There are a number of states in which a domain may exist. They are:
■
Starting (initializing)
■
Running
■
Paused
■
Suspended
■
Stopping (shutting down)
■
Powered off (stopped)
A start operation can take the domain from the stopped (powered down) state to the
paused state, or the running state. From the running state, a suspend action takes the
domain to the suspended state, and a resume operation takes it back to the running
state. The transition to and from the suspended state could also happen from the
paused state.
A domain in the running state could go to the paused state through the pause
command, and return to the running state by the resume command. A domain in the
running state could transition into the stopped state through a clean, or hard shut
down.
5.2 Using the xm Command-Line Interface
You can create, destroy, manage and migrate domains using the xm command-line
interface. You can enter parameters to the xm command-line tool in the format:
xm [option] [argument]
For example, to pause a domain called mydomain, enter
