Instance Manager Services, Cloud Infrastructure Automation Agent

PACI-im service includes PACI IM service and PACI vm2vf service. PACI-im file location on IM node: /etc/init.d/PACI-im

Purpose of PACI IM – main management process, requires activemq service, communicates with CloudBlue Commerce over REST API. Configuration file location – /usr/local/share/PACI-im/IM-config.xml

Purpose of PACI vm2vf – main VE management process, communicates with slave nodes over Virtuozzo SDK, talks with dispatcher.

Instance Manager (IM) requires the following service to be running on the IM node:

ActiveMQ – synchronization manager between PACI-im and PACI-aps. File location on IM node – /etc/init.d/activemq-server

Starting and checking status of ActiveMQ service

```
# service activemq-server start
```

Once this service is started, the IM service can also be started.
