attach both virtio-scsi and virtio-blk to an instance

Hello, I am searching whether it is possible to use both virtio-scsi and virtio-blk at the same time for one instance. I knew it was possible to use each of them separately. I have this requirement because virtio-blk is not possible to support as many as devices like virtio-scsi, but we still want to keep virtio-blk for performance reasons and for legacy instances. Thank you for help. -- Best Regards, Jiatong Shen
