If you're planning to do it that way, make sure you install version 3.x 
of ovirt-engine-sdk-python. Newer versions (4.x) differ too much in 
syntax.

Also, if you want to move a whole Storage Domain, you might be 
interested in listing VMs by the storage domain name, i.e.:

api.vms.list(query='Storage=myoldstoragedomain')

That will return a list of all machines in that storage domain.
