When starting a migration with --timeout, we create a thread to call the migration API and in parallel setup a timer for the timeout. The description of --timeout says: "run action specified by --timeout-* option (suspend by default) if live migration exceeds timeout", which is not really the way this feature was implemented. Before live migration starts we first need to contact the source to get the domain definition and send it to the destination where a new QEMU process has to be started. This can take some (unpredictably long) time while the timeout timer is already running. If a very short timeout is set (which doesn't really make sense, but it's allowed), we may even end up taking the timeout action before the actual migration had a chance to start. With this patch the timeout is started only after we get non-zero dataTotal from virDomainGetJobInfo, which means the migration (of either storage or memory) really started. https://issues.redhat.com/browse/RHEL-41264 Signed-off-by: Jiri Denemark <jdenemar@redhat.com> Reviewed-by: Michal Privoznik <mprivozn@redhat.com> |

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
