[libvirt] [PATCH 0/7] Add notification for memory hot-unplug failure

[Peter Krempa]

Add a new libvirt event VIR_DOMAIN_EVENT_ID_DEVICE_REMOVAL_FAILED that will
handle failure to unplug a device if we are certain that it will not be unplugged
and wire up the ACPI_DEVICE_OST qemu event that is emitted on memory hotunplug
failure so that the event is propagated and the API fails in such case.

Along with that a few refactors were necessary.

Peter Krempa (7):
  qemu: hotplug: Properly handle errors in
    qemuDomainWaitForDeviceRemoval
  qemu: hotplug: Refactor semantics of qemuDomainWaitForDeviceRemoval
  qemu: Use domain condition for device removal singalling
  qemu: hotplug: Add support for signalling device unplug failure
  Add VIR_DOMAIN_EVENT_ID_DEVICE_REMOVAL_FAILED event
  qemu: monitor: Add support for ACPI_DEVICE_OST event handling
  qemu: process: Wire up ACPI OST events to notify users of failed
    memory unplug
