From: wangmeiling <[email protected]> Virtio-gpu malloc memory for the queue when it realized, but the queues was not released when it unrealized, which resulting in a memory leak. In addition, vm_change_state_handler is not cleaned up, which is related to vdev and will lead to segmentation fault when VM shutdown.
