https://bugzilla.redhat.com/show_bug.cgi?id=999352 Since commit v1.0.5-56-g449e6b1 (Pull parsing of migration xml up into QEMU driver APIs) any attempt to rename a domain during migration fails with the following error message: internal error Incoming cookie data had unexpected name DOM vs DOM2 This is because migration cookies always use the original domain name and the mentioned commit failed to propagate the name back to qemuMigrationPrepareAny.
