Change subject: core: Improve performance of getVmDeviceByVmId ...................................................................... core: Improve performance of getVmDeviceByVmId getVmDeviceByVmId is calling a query on vm_device_view using vm_id as a parameter. Since vm_id does not have an index, this query takes a long time. This patch added an index, which improved performance in the perf environemnt from 56ms to 0.2ms.
