Phil Day b32d01d44c Stop, Rescue, and Delete should give guest a chance to shutdown ... Currently in libvirt stop, shelve, rescue, and delete 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 the relevant 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. The timer logic itself is changed from simple loop counting with one second sleeps to a more precise approach, since testing showed that other calls in the loop could introduce a difference of up to +50% on the expected duration. This can extent the default two minute to three minutes, which would not be acceptable in some environments and breaks some of the tempest tests. A separate config value defines what the default shutdown behaviour for delete should be (default False to keep compatibility with current behaviour). This code is structured to enable a subsequent API change to add clean/forced options to the stop and delete methods Also as a minor tidy-up moved the repeated definition of FakeLoopingCall in test_libvirt be common across tests Partially-Implements: blueprint user-defined-shutdown Closes-Bug: #1196924 DocImpact Change-Id: Ie69aa2621cb52d6fefdc19f664247b069d6782ee		2013-12-15 16:20:50 +00:00
