Finding number of shutdown guests on a host - Openstack

I am trying to figure out how many shutdown guests (or tenants) there are on a host versus the total number of guests on a host. I'm able to hard-code it using nova list, grep and wc -l but I was wondering if there are any flags or cleaner ways of getting this information.

Thanks

Solution

I have tested these commands in OpenStack Newton.

You can list all the shutdown guests by running the below command

nova list --status SHUTOFF

If you want to list shutdown guests on a compute node, find the compute hostname and use the name with --host argument

nova host-list
nova list --host compute1 --status SHUTOFF
