If you mean the device name in /dev is not what's specified when creating the volume attachement, than I think that's a known issue - ultimately cinder just doesn't have much control over how the host OS on the VM enumerates new devices. You're probably best using /dev/disk/by-id/virtio-<VolumeId> if that is your issue, and ignoring the mountpoint option to the volume attachment request.
