[libvirt] 'starting' a domain using Python libvirt..

I'm trying to figure out how to start a domain .. and I can't figure out what method to use.. When I do this:

...

...

dir(conn.lookupByName('my-vm-1'))

I get these options: ['ID', 'OSType', 'UUID', 'UUIDString', 'XMLDesc', '__del__', '__doc__', '__init__', '__module__', '_conn', '_o', 'attachDevice', 'autostart', 'blockStats', 'connect', 'coreDump', 'create', 'destroy', 'detachDevice', 'info', 'interfaceStats', 'maxMemory', 'maxVcpus', 'migrate', 'name', 'pinVcpu', 'reboot', 'resume', 'save', 'setAutostart', 'setMaxMemory', 'setMemory', 'setVcpus', 'shutdown', 'suspend', 'undefine'] I don't see a method to start a domain up.. What am I missing here? thanks!
