QEMU will soon (patches are available on qemu-devel) get support for migration events which will finally allow us to get rid of polling query-migrate every 50ms. However, we first need to be able to wait for all events related to migration (migration status changes, block job events, async abort requests) at once. This series prepares the infrastructure and uses it to switch all polling loops in migration code to pthread_cond_wait.

Version 3 (see individual patches for details): - most of the series has been ACKed in v2 - "qemu: Use domain condition for synchronous block jobs" was split in 3 patches for easier review - minor changes requested in v2 review
Version 2 (see individual patches for details): - rewritten using per-domain condition variable - enahnced to fully support the migration events
Jiri Denemark (24): conf: Introduce per-domain condition variable qemu: Introduce qemuBlockJobUpdate qemu: Properly report failed migration qemu: Use domain condition for synchronous block jobs qemu: Cancel storage migration in parallel qemu: Abort migration early if disk mirror failed qemu: Don't mess with disk->mirrorState Pass domain object to private data formatter/parser qemu: Make qemuMigrationCancelDriveMirror usable without async job qemu: Refactor qemuMonitorBlockJobInfo qemu: Cancel disk mirrors after libvirtd restart qemu: Use domain condition for asyncAbort qemu_monitor: Wire up SPICE_MIGRATE_COMPLETED event qemu: Do not poll for spice migration status qemu: Refactor qemuDomainGetJob{Info,Stats} qemu: Refactor qemuMigrationUpdateJobStatus qemu: Don't pass redundant job name around qemu: Refactor qemuMigrationWaitForCompletion 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 qemu: cancel drive mirrors when p2p connection breaks
ACK to the above ones once qemu accepts the event stuff.
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
