# The legacy `nova` CLI is retired: python-novaclient no longer ships a `nova`
# command. Use the `openstack` CLI equivalents instead (same information):
# (previous equivalent: nova list --fields name,OS-EXT-SRV-ATTR:instance_name,OS-EXT-SRV-ATTR:host --name vm4qos*)

# list servers with host / instance_name columns
openstack server list --long -c ID -c Name -c 'OS-EXT-SRV-ATTR:host' -c 'OS-EXT-SRV-ATTR:instance_name'

# filter by name pattern (regex, repeat for each vm4qos* server)
openstack server list --long --name '^vm4qos' -c ID -c Name -c 'OS-EXT-SRV-ATTR:host' -c 'OS-EXT-SRV-ATTR:instance_name'
