does your controller have nova-compute installed ? I mean, if it has, your question is can we live migrate between two compute nodes

This is what I get if I type the command on my controller node

controller@controller-ESPRIMO-P400:~$ openstack host list

+------------------------------------------------------+------------------+----------+

| Host Name................................................| Service.........| Zone....|

+------------------------------------------------------+------------------+----------+

| controller-ESPRIMO-P400........................| consoleauth | internal |

| controller-ESPRIMO-P400........................| scheduler.....| internal |

| controller-ESPRIMO-P400........................| conductor.....| internal |

| compute-HP-Compaq-6200-Pro-SFF-PC | compute.......| nova.....|

+------------------------------------------------------+------------------+----------+

So Im guessing the controller doesnt have the nova-compute installed in it.

In Your case, you have only one compute node.

Live migration is functionality for moving an instance hosted on one compute node to another compute node. So, If you have multiple compute nodes, then only you can use live migration.

So how can I include the compute node component(nova) in my controller node so that I have 2 compute nodes to do the VM Migration?

You just go through the same installation steps as you did with the Compute node.

Use Installation guide: Step 1 : Follow all steps to setup environment Step 2: Install nova on compute node (skip controller setup steps) Step 3: Install Neutron component for compute node (Skip controller setup steps)
