This series introduces 2 new APIs to allow long running jobs to be monitored and cancelled. This applies to virDomainMigrate, virDomainSave, virDomainRestore and virDomainCoreDump at least. The implementation is provided for QEMU only, any others that are able to implementation can do so as desired. Usefulness of these new APIs requires use of multiple threads on a single connection, or multiple connections, since the main API calls are still all fully blocking. Instead a parallel thread or process can monitor. This can be seen with virsh In termainl 1 $ virsh save demo demo.img In terminal 2 $ ./virsh domjobinfo demo Job type: Unbounded Time elapsed: 795 ms Data processed: 22446080 bytes Data remaining: 219119616 bytes Data total: 241565696 bytes Memory processed: 22446080 bytes Memory remaining: 219119616 bytes Memory total: 241565696 bytes $ ./virsh domjobinfo demo Job type: Unbounded Time elapsed: 1669 ms Data processed: 139784192 bytes Data remaining: 101781504 bytes Data total: 241565696 bytes Memory processed: 139784192 bytes Memory remaining: 101781504 bytes Memory total: 241565696 bytes $ ./virsh domjobabort demo Back in terminal 1 error: Failed to save domain demo to demo.img error: operation failed: Migration was cancelled by client -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
