This commit makes sure that the Python list vms_list is not mutated while the code is iterating through it. To the best of my knowledge, this is a problematic operation. To rectify this issue, a new temporary list is instantiated, and the VM objects that have shut down are appended to the temporary list, which is afterwards used to remove the shut-down VM objects from the vms_list.
