Many questions... ;)

* Does this error _always_ occur?

* What do you mean by "it told me that the l4linux is down"?

* Do I understand correctly, that you run the 2 L4Linuxes in 2 different
instances of Qemu? If so, communication between these instances does not
need any special ORe configuration, because this is just like having to
real computers with Linux running in a network and you should be able to
 one machine from the other e.g. by using SSH.

* Can you please post
  * Your L4Linux configuration
  * Your L4Linux loader script (l4linux.cfg)
  * The Qemu command line used to start your setup
  * The _full_ log output

Kind regards,
Bjoern
