Verifying the Compute Installation

You can ensure all the Compute services are running by using the nova-manage command, as root:

# nova-manage service list

In return you should see "smiley faces" rather than three X symbols. Here's an example.

Binary           Host     Zone    Status     State Updated_At
nova-compute     myhost    nova    enabled    :-)   2012-04-02 14:06:15
nova-cert        myhost    nova    enabled    :-)   2012-04-02 14:06:16
nova-scheduler   myhost    nova    enabled    :-)   2012-04-02 14:06:11
nova-network     myhost    nova    enabled    :-)   2012-04-02 14:06:13
nova-consoleauth myhost    nova    enabled    :-)   2012-04-02 14:06:10

	Note
	If you see three X symbols and are running services on separate hosts, ensure that ntp is synchronizing time correctly and that all servers match their time. Out-of-sync time stamps are the most common cause of the XXX state.

You can find the version of the installation by using the nova-manage command, as root:

# nova-manage version

The version number 2013.1 corresponds with the Grizzly release of Compute.
