Yes, I have QNX (although I only tried QNX 6.3.2) as guest with working network.

As I posted on [1], I needed "-net nic,model=ne2k_pci" and to follow the
instructions in [2], the part that says: "If this is not done, networking will
not work, so we have to manually start it every time. To do this, type".
Although I've only done this the first time and when I re-start the guest it
just works.

I don't know if this would work on QNX 6.5, but I suspect it does.




Thanks a lot,
Rodrigo
