The ovs-agent command-line tool enables you to configure and control Oracle VM Agent. The following sections discuss using the ovs-agent command-line tool. See "ovs-agent" in Appendix A, "Command-Line Tools" for more details on the ovs-agent command-line tool options.
You can change the default configuration with the Oracle VM Agent configuration script, ovs-agent. To configure Oracle VM Agent:
As the root user, run the Oracle VM Agent configuration script:
# service ovs-agent configure
You are prompted to enter the IP addresses that are allowed to access to the computer.
;network access control by ip -- ;rules := if addr.match(allow) and not addr.match(deny): return True ;pattern items delimited by comma and could be ;10.1.1.1 #single ip ;10.1.1.* #range ;10.1.1.1/24 #range in CIDR format ;default to allow all, deny none allow=* allow=
* (asterisk) to allow all IP addresses access to the computer. Alternatively, enter a list of IP addresses for computers for which you want to allow access, while restricting all others. The default is to allow all computers to access the computer (

You are prompted to enter the shared disk search path.
now deny= ;share_disk_pat -- ;set the directories for searching sharable block devices ;directories should be seperated by ':' ;if not set, /dev/mpath/* will be used share_disk_pat=/dev/mpath/* share_disk_pat=
Enter the shared disk search path. You should not use the path /dev/mapper/x for multipath devices, only use the path /dev/mpath/x.
You are prompted whether you want to change the Oracle VM Agent password.

Oracle VM Agent is started automatically when the computer starts. To manually start Oracle VM Agent, enter
# service ovs-agent start
Oracle VM Agent is started.
Alternatively, if Oracle VM Agent is already running, you can stop and restart it with the command
# service ovs-agent restart
Oracle VM Agent is stopped, and restarted.
To stop Oracle VM Agent, enter
# service ovs-agent stop
Oracle VM Agent is stopped.
Note:When Oracle VM Agent is stopped, Oracle VM Manager cannot manage the Oracle VM Server or the guests running on it.
If you shut down or restart the Oracle VM Agent on an HA-enabled Oracle VM Server on which guests are running you are prompted to:
Migrate or Power Off the guest(s) using Oracle VM Manager. When the guests have been migrated or Powered Off, the Oracle VM Agent shuts down.
Shut down the guest(s) and shut down Oracle VM Agent.
Cancel the shutdown operation.
