Problem:
I want to associate a single vm without GUI but it doesn’t work:
LANG=C hammer compute-resource associate-vms --id 4 --vm-id 500a83fc-33c0-83fe-4616-805246457669
Could not associate the virtual machines:
wrong number of arguments (given 1, expected 0)
(Used VMWare VM ID)
LANG=C hammer --debug compute-resource associate-vms --id 4 --vm-id 4222
[ERROR 2026-09-22T16:21:07 Exception] Resource compute_resource not found by id '4'
Could not associate the virtual machines:
Resource compute_resource not found by id '4'
