Nova Command¶
This is a wrapper nova command provided by cloudmesh which in turn calls the openstack nova command on the target cloud. This also provides you with the capability of setting the target cloud. However, we recommend not using the command and instead use the cloudmesh command sas they allow for information caching
The manual page of the key command can be found at: Nova
Setting the Target Cloud¶
You may set the target cloud on which the nova command should run as follows:
$ cm nova set india
india is set
Note that if you do not set a target cloud, default cloud considered is ‘india’.
Getting the Cloud Info¶
You may get the cloud info in the following manner:
$ cm nova info
WARNING: OS environment variable OS_REGION not found
+----------------+--------------------------------------------------------+
| Variable | Value |
+----------------+--------------------------------------------------------+
| OS_REGION | None |
| OS_USERNAME | albert |
| OS_CACERT | /home/albert/.cloudmesh/clouds/india/kilo/cacert.pem |
| OS_TENANT_NAME | fg478 |
| OS_AUTH_URL | https://i5r.idp.iu.futuregrid.org:5000/v2.0 |
| OS_PASSWORD | ******** |
+----------------+--------------------------------------------------------+
By default it gives the ‘india’ cloud info. To check for specific cloud, here is an example for kilo cloud:
$ cm nova info kilo
+----------------+------------------------------------------------+
| Variable | Value |

| OS_REGION | None |

The syntax is the same as what is used for openstack nova. Following are couple of examples:
