I will give it a test spin. I cannot judge the test script you added. Good thing that you
added it!

    Why not be lenient and consider the id as part of ids?
    You are being strict on something that isn't hurtful but an empty ids when no id is given
is not checked!

> Currently list VM can only be called using a single VM ID. So if there is a need to query
a set of VMs using ID then either multiple list VM calls need to be made or all VMs needs
to be fetched and then do a client side filtering. Both approaches are sub-optimal - the former
results in multiple queries to database and the latter will be an overkill if you need a small
subset from a very large number of VMs.

With the new parameter the syntax would look like
