No, currently it is not possible. We don't have multiplexed data streams
over virConnect. While that might be relatively easily to implement for
some transports (like libssh2), for some it would require change of the
transport layer (e.g. TCP/UNIX sockets don't support multistreaming, so
we'd need to use SCTP).
Or implement multistreaming ourselves which is something I'd like very
much to avoid.

I'm not check keepalive messages,but why not possible to extend connect
reply to pass connid and send pong messages from client with connid? If
someone sends keepalive message with different connid extend it timeout?
