When we boot instance with force host, and the instance request some pci devices, all the scheduler filters would been ignored, include: PciPassthroughFilter. So if the specified host can't apply the pci request, PciDeviceRequestFailed exception would been raised from HostState.consume_from_instance, at this time the part of compute resource had been updated, e.g. vcpus, ram, disk and so on, we should make the resource of HostState having chance to been reverted in order to avoid resource leaking. When the exception is raised from self.pci_stats.apply_requests(), catch it and don't set the update field of HostState, HostState will be synced with db in next scheduling, the resource is reverted at that time.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
Developers wishing to work on the OpenStack Nova project should always base their work on the latest Nova code, available from the master GIT repository at:
Developers should also join the discussion on the mailing list, at:
