Playing with Oracle Solaris 11.2’s Openstack cloud

13.Click on Images and snapshots. You can see there are two pre-built images. One for non-global zone and another for kernel zone. If you want to use kernel zone image, make sure your hardware supports nested virtualization.(Refer Step 6).

14. If you want “Solaris Non-global zone” , Just click on launch. In the window,enter the instance flavor,image details, access groups, and network.

15.Click on Access and Security to provide access to the instance.

If you do not have keypair, just import it like below from Access & Security .

In this window ,enter the key pair name & public rsa key.You need to provide the key from the system from where you want to access this nova instance.

16.In the networking tab , just drag the network which we have created earlier.Click on Launch to start nova instance.

17.In the instance tab , you can see that nova instance is deploying as non-global zone.

How to access this instance ?

You can access the instance from  machine keypair you have imported it on openstack.(Refer Step 15)

How the nova instance looks from the Oracle Solaris level ? How the filesystems are mapped ?

Oracle Solaris just creates a non-global zone with exclusive IP and creates the dedicated ZFS dataset for that nova instances.

Same way, you can deploy N-number of nova instances.We will see how to create a new project and how  to provide access to specific projects in up coming articles.
