This patch concerns the time when a VM is being unshelved and the compute manager set the task_state to spawning, claimed resources of the VM and then called driver.spawn(). So the instance is in vm_state SHELVED_OFFLOADED, task_state spawning. If at this point a new update_available_resource periodic job is started that collects all the instances assigned to the node to calculate resource usage. However the calculation assumed that a VM in SHELVED_OFFLOADED state does not need resource allocation on the node (probably being removed from the node as it is offloaded) and deleted the resource claim. Given all this we ended up with the VM spawned successfully but having lost the resource claim on the node. This patch changes what we do in vm_state SHELVED_OFFLOADED, task_state spawning. We no longer delete the resource claim in this state and keep tracking the resource in stats.

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:
