This thought crossed my mind a few days ago and has been bugging me...
Has anyone ever tried implementing cisco hardware in qemu? @[email protected]

Qemu:
  • has good and established JIT code.
  • has other hardware that can be used as reference if needed.
  • probably has some hardware that can be used as is. (maybe cpu+bus+interrupts+memory?)
  • after a quick glance at some qemu code, implementing hardware looks uncomplicated. (no idea about modifying the build system to compile the new code)

dynamips:
  • has different JIT code for the ppc cpu and mips cpu, in different stages of implementation.
  • has lots of unfinished hardware features, all over the place. (much more than what I initially thought =~~)
  • has other convenient goodies like the hypervisor, complex topologies in the same process, available hardware depends on the router model, ...

The more I think about it, the better is sounds... therefore someone might have already tried it.

I can definitely see the advantages to taking this approach.

This is a very good idea and this would require a lot of hard work. So why not if someone is dedicated to it and can push his work upstream.
