6.2. Upgrading Compatibility Levels
Example 6.1. Upgrading compatibility levels
The API reports the following compatibility levels for Red Hat Enterprise Virtualization Manager 3.0 instance:
<host ...>
...
<version major="3" minor="0"/>
...
</host>
<cluster ...>
...
<version major="3" minor="0"/>
<supported_versions/>
...
</cluster>
<data_center ...>
...
<version major="3" minor="0"/>
<supported_versions/>
...
</data_center>
All hosts within a cluster are updated to VDSM
3.1 and the API reports:
<host ...>
...
<version major="3" minor="1"/>
...
</host>
<cluster ...>
...
<version major="3" minor="0"/>
<supported_versions>
<version major="3" minor="1"/>
</supported_versions>
...
</cluster>
<data_center ...>
...
<version major="3" minor="0"/>
<supported_versions/>
...
</data_center>
The cluster is now updatable to
3.1. When the cluster is updated, the API reports:
<cluster ...>
...
<version major="3" minor="1"/>
<supported_versions/>
...
</cluster>
<data_center ...>
...
<version major="3" minor="0"/>
<supported_versions>
<version major="3" minor="1"/>
</supported_versions>
...
</data_center>
The API user updates the data center to
3.1. Once upgraded, the API exposes features available in Red Hat Enterprise Virtualization 3.1 for this data center.
