In this post I am going to show you basic functionality of openstack cinder (volume) service functionality by creating volume on internal storage. Attaching that volume to VM. Create partition on that volume in client machine and test partition remove and detaching volume from VM.
Lets take one running state vm for cinder testing as we can do this operation on the fly. I have one VM name testvm.
Check the disk and partitions on the VM. I can access the testvm using private IP and public IP. Lets access it using private IP using unique network namespace.
First check private-net network ID and test the ping to private IP of VM using network namespace. For more details about basic networking in openstack check my last blog posts.

In first part we saw how to create new VM in internal/private network now in this post we will see how to add external/public network to VM instance.
First check if our existing VM is in running state.
Now also check available network using CLI and using Openstack Dashboard.

Once you install Openstack in single node or multinode setup next thing is to setup network. To understand networking in Openstack is little tedious job. This post is to describe basic Openstack networking concept by creating internal/external networking and testing the same.
First delete all default network like public and private which were created by default after Openstack installation using
#neutron net-delete <net-name>
Let us create new internal network first.
Create subnet for network private-net with subnet address 10.0.0.0/24
