Okay, this is going to be a long message. :) We're calling it as: dom.migrateToURI2(duri, muri, xml_str, logical_sum, None, CONF.live_migration_bandwidth) Here are the supplied arguments: duri = u'qemu+tcp://compute-0/system' muri = u'tcp://compute-0' flaglist = ['VIR_MIGRATE_UNDEFINE_SOURCE', 'VIR_MIGRATE_PEER2PEER', 'VIR_MIGRATE_LIVE'] logical_sum = 19, (logical OR of flaglist) CONF.live_migration_bandwidth = 0 Grabbing original XML prior to migration: dom_xml = etree.fromstring(dom.XMLDesc(0))
