2.8. Example: Listing the Size of a Virtual Machine

The API class provides access to a virtual machine collection, named vms. This collection in turn contains a disks collection that describes the details of each disk attached to a virtual machine.

Example 2.7. Listing the Size of a Virtual Machine

This Python example prints a list of the virtual machines in the Red Hat Enterprise Virtualization environment along with their total disk size in bytes: 
from ovirtsdk.api import API
from ovirtsdk.xml import params

try:
    api = API (url="https://HOST",
               username="USER@DOMAIN",
               password="PASS",
               ca_file="ca.crt")

    virtual_machines = api.vms.list()

    if len(virtual_machines) > 0:

        print("%-30s  %s" % ("Name","Disk Size"))
        print("==================================================")

        for virtual_machine in virtual_machines:

            disks = virtual_machine.disks.list()

            disk_size = 0

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

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

    api.disconnect()

except Exception as ex:
    print "Unexpected error: %s" % ex
