[9fans] qemu and networking

Hi,

I've installed plan9 on a plan9.raw.img file via qemu and I'm able to boot on it.
How can I transfer files between plan9 and my host (I'm under macos)?
I've followed http://plan9.bell-labs.com/wiki/plan9/installing_plan_9_on_qemu/index.html
and run


qemu -hda Plan9.qcow2.img -net nic -net user

but from plan9 when I do

 rc> ip/ping 10.0.2.2 nothing happens.

I've only ever gotten networking working on OS X using the tun/tap driver. It's a bit of a pain in the
ass but works quite well.

The user-mode (SLIRP) network stack in QEMU doesn't support ICMP.

You can reuse your qcow image with virtualbox where this is
relatively easy to fix.

I use
QEMU emulator version 1.6.0, Copyright (c) 2003-2008 Fabrice Bellard
I don't give any networking options at the command line and it works
for me. I use 9front but I don't think it matters.

I think Yoann asked how to connect to Plan9 from MacOS, right?
You have to use tun/tap and maybe drawterm to connect to Plan 9
from MacOS, and then, for example, copy files via /mnt/term/.

In his mail he was trying to reach the host from the guest.
But the other way around he would need tun/tap. That's correct.

Oh btw I'm on linux not os x. But didn't think that makes a difference for
guest network.

Not sure the files transfer direction was mentioned at all:
English is far from being my native language but *between* vs.
*from...to* sound different to me. ;-)

ip/ping is a plan 9 command
10.0.2.2 is the ip of the (simulated) gateway from the guest
