Thanks for the info! I'll look into this.

I agree on this principle of avoiding duplication.
However my feeling is: IMHO different hypervisor sockets were developed
independently without coordination and the implementation details could be
so different that an enough generic framework/infrastructure is difficult,
e.g., at first glance, it looks AF_IUCV is quite different from AF_VSOCK and
this might explain why AF_VSOCK wasn't built on AF_IUCV(?).

I'll dig more into AF_IUCV, AF_VSOCK and AF_HYPERV and figure out what
is the best direction I should go.

Thanks,
