Thanks, I pushed all patches which did not rely on the new MIGRATION event, in other words, all except the following ones: qemu_monitor: Wire up MIGRATION event qemuDomainGetJobStatsInternal: Support migration events qemu: Update migration state according to MIGRATION event qemu: Wait for migration events on domain condition DO NOT APPLY: qemu: Work around weird migration status changes Jirka -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
