Hi Emeline,

After playing around with the Python SDK for a bit, I have had some success in getting the total size of a virtual machine via the following:

First, get a list of virtual machines in the environment:

virtual_machines = api.vms.list()

    for virtual_machine in virtual_machines:

Second, get the list of disks attached to a virtual machine:

        disks = virtual_machine.disks.list()

        disk_size = 0

For each of the disks, get the disk size and add it to the total:

        for disk in disks:
            disk_size += disk.get_size()

Print the results:

        print("%-30s: %d" % (virtual_machine.get_name(), disk_size))

Hope this does the trick.

Kind regards,

Andrew
