To Know the Hypervisors attached to the Controller Node

nova hypervisor-list




To Know about the list of instances running in a particular Compute Node,.
This will not list the IP Address of the VMs

nova hypervisor-servers  <Hypervisor Host Name>




To Know about the list of open stack instances running and IP Address
in a particular Compute Node,.


nova list --host <Hypervisor Host Name>



To find stopped VMs, ,

nova list --status SHUTOFF

To find deleted VMs, or stopped servers, there are two options available:

nova list --status DELETED

or

nova list --deleted

    
Another Command to check where the VMs in all states ( Running, Deleted, Shut Down etc)

nova-manage vm list | column -t

To know the disk file of the VM 

ls -al /var/lib/nova/instances/ 

To Know about a particular Instance,
