vm object has statistics sub-collection, you can access it by: vm.statistics.list(),

in python, you can see object's attributes by accessing __dict__/__getattr__/dir(object)/etc.,
vm.__dict__ will do the job for you, however i'd suggest you using some IDE (i'm using Eclipse + PyDev plugin),
this way you'll be able accessing object attributes simply by Ctrl+SPACE auto-completion.
