> 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.
> The proposal is to have an additional parameter to specify a list of VM IDs for which the data needs to be fetched. Using this the required VMs can be queried in an efficient manner. With the new parameter the syntax would look like
> http://localhost:8096/api?command=listVirtualMachines&listAll=true&ids=eddac053-9b12-4d2e-acb7-233de2e98112,009966fc-4d7b-4f84-8609-254979ba0134
> The new 'ids' parameter will be mutually exclusive with the existing 'id' parameter.
