    Stop and delete operations should give guest a chance to shutdown

    Currently in libvirt stop and delete operations simply destroy the
    underlying VM. Some GuestOS's do not react well to this type of
    power failure, and so it would be better if these operations
    followed the same approach as soft_reboot and give the guest as
    chance to shutdown gracefully. Even where VM is being deleted,
    it may be booted from a volume which will be reused on another
    server.

    The change is implemented by adding a clean_shutdown parameter
    to delete and stop methods from the compute/api layer downwards
    and into the virt drivers. The implementation in the libvirt
    driver is also provided. Other drivers are modified just to
    expect the additional parameter.

    The timer configuration value previous used by soft_reboot in
    libvirt is moved up to virt/driver so it can be used by other drivers.

    A separate config value defines what the default shutdown
    behaviour for delete should be (default False to keep compatibility
    with current behaviour).

    This code enables a subsequent API change to add add clean/forced
    options to the stop and delete methods

    Fixes bug 1196924

Hi, everyone!

I have a question regarding the list of operations which give the GuestOS a chance to shutdown. I am not sure about "delete", as it is not in the spec.

Could anyone please clarify wether the following list is complete:
- nova stop [–hard-shutdown]
- nova rescue [–hard-shutdown]
- nova resize [–hard-shutdown]
- nova shelve [–hard-shutdown]

Thanks in advance!

    Controlled shutdown for rescue, shelve, and resize

    Rescue, shelve, and resize operations now give the guest OS
    a chance to shutdown cleanly before powering off the VM.

    The shutdown behavior is defined by the shutdown_timeout
    conf parameter
