In particular, are you thinking about Erlang-style code swapping of processes? OCaml's runtime is pretty much the opposite model to Erlang's in this regard, as it performs native compilation of code and discards a lot of type information. The best way to perform hotswapping of MirageOS unikernels is to do it at the application level (e.g. a load balancer) rather than at the virtual machine level. regards, Anil _______________________________________________ MirageOS-devel mailing list MirageOS-devel@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/cgi-bin/mailman/listinfo/mirageos-devel
