Managing Multiple Zones 3.4

A Zone is essentially a group of interconnected physical hosts with hypervisors controlled by OpenNebula. A Zone can be added to the oZones server, providing valid oneadmin credentials, so it can contribute to the list of aggregated resources presented by the oZones component. A Zone can be further //compartmentalized// in [[.:vdcmngt|Virtual Data Center or VDCs]]. {{INLINETOC}} ====== Adding a new Zone ====== This guide assumes that the oZones command line interface is correctly [[.:ozonescfg#installation|installed]] and [[.:ozonescfg#configure_ozones_client|configured]]. Zones resource can be managed using the **onezone** command. In order to create a zone, we will need a Zone template, with the necessary information to setup such resource:


NAME=MyZone
ONENAME=oneadmin
ONEPASS=opennebula
ENDPOINT=http://zone.domain.name:2633/RPC2
SUNSENDPOINT=http://zone.domain.name:9869
SELFENDPOINT=http://zone.domain.name:4567/ui

The //oneadmin// credentials are checked against the OpenNebula present in the Zone by requesting the list of available hosts. No changes are made to the OpenNebula whatsoever. Let's create a Zone: $ onezone create myzone.template ID: 1 Now we can list the available zones: $ onezone list ID NAME ENDPOINT 1 MyZone http:%%//%%zone.domain.name:2633/RPC2 ====== Examining a Zone ====== We can further examine the contents of the zone with the **onezone show** command: $ onezone show 1 ZONE zone0 INFORMATION ID : 1 NAME : zone0 ZONE ADMIN : oneadmin ZONE PASS : 4478db59d30855454ece114e8ccfa5563d21c9bd ENDPOINT : http:%%//%%zone.domain.name:2633/RPC2 # VDCS : 0 Zone resources can be specifically queried with **onezone show ** plus one of the following flags: * ''vmtemplate'' for VM templates * ''image'' for Images * ''user'' for Users * ''vm'' for Virtual Machines * ''vnet'' for Virtual Networks * ''host'' for Hosts Let's query the hosts of the newly created zone: $ onezone show 1 host ZONE zone0 INFORMATION ID : 1 NAME : MyZone ZONE ADMIN : tinova ZONE PASS : 4478db59d30855454ece114e8ccfa5563d21c9bd ENDPOINT : http:%%//%%zone.domain.name:2633/RPC2 # VDCS : 0 ID NAME RVM TCPU FCPU ACPU TMEM FMEM AMEM STAT 0 MyHost 0 0 0 100 0K 0K 0K on 1 EC2Host 0 0 0 100 0K 0K 0K on 2 64BitsComp 0 0 0 100 0K 0K 0K on ====== Deleting a Zone ====== We can delete a zone with **onezone delete**, providing the Zone ID: $ onezone delete 1 Resource zone with id 1 successfully deleted ====== Using the oZones GUI ====== Pointing the browser to


http://ozones.server.domainname:6121

Will give access to the oZones GUI, where all the functionality of the CLI is offered. {{ :documentation:rel3.0:generalozonesgui.png?700 |}} ===== Examining Aggregated Resources ===== Also, in the GUI there is the ability to see the aggregated resources from multiple zones: Templates, Images, Users, Virtual Machines, Virtual Networks and Hosts. {{ :documentation:rel3.0:aggregatedozonesgui.png?700 |}}
