Hi Ahmad,
There is currently no such functionality in gem5, and networking is only
supported within one simulator instance. At the moment you can connect two
systems (as there is no ethernet switch), but on the developer list there has
been discussions mentioning ongoing work to create an Ethernet switch, which
would allow more systems (>2) to communicate over Ethernet.
Coming back to your original question, the tricky part with host
bridging/NATing is the different time scales. The simulated system is perhaps
1.000 - 10.000x slower than the host system, and this difference in time scale
confuses the TCP/IP stack(s). Also, having an external network connection will
make simulations non-deterministic, which is often undesirable. All this said,
if you have ideas of how to make it work, please feel free to share and discuss
on the list.

Subject: [gem5-users] Configure networking in Gem5 X86 FS
Hi,
I have set up eth0 interface in X86 FS mode through e1000 driver. But I cannot
SSH or ping the the host machine or any other IP or the network. I noticed that
GEM5 does not create any bridge/NAT on the host machine.
How can I configure networking in gem5 so that I can SSH from any machine on
the network or the host machine into gem5 X86 FS Ubuntu?
Thanks.
-Ahmad
