Hi,
We've run into a problem with libvirt 1.1.2 and are looking for some comments on whether this is a bug or design intent.
We're trying to use migrateToURI() but we're using a few things (numatune, vcpu mask, etc.) that may need adjustment during the migration. We found that migrateToURI2() mostly works if we use XML created by copying the domain XML from the running instance and modifying the appropriate sections.
The problem that we're seeing is that the serial console checking in libvirt/src/conf/domain_conf.c::virDomainDefCheckABIStability() is failing even though we haven't touched the serial console XML:
I think we will have to see the XML your passing before and after edit to figure out what's going wrong. Also, showing all the arguments you are invoking the migration APIs with.
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))
Can you retry this whole thing but pass VIR_DOMAIN_XML_MIGRATABLE instead of 0.
