Change subject: Fix the race between committed memory and pending memory updates ...................................................................... Fix the race between committed memory and pending memory updates The pending values are cleared once the VM monitor get the asynchronous message announcing the state change to Powering Up (via RunVmCommnand#OnPowerringUp, SchedulingManager#clearVm and VdsManager#updatePendingData methods). But the committed memory of host is not recomputed here. The committed memory is recomputed in HostMonitoring#refreshCommitedMemory which gets called when the polling returns new host data. But that can take up to 15 seconds. So we have at max a 15 second window between when we clear the pending values and when we update the committed memory information. The solution calls refreshCommitedMemory from the updatePendingData, and provides the list of all VMs from the DB that should already contain the newly received VM.
