well, i don't see how masquerading and forwarding will help me in
pinging from guest to host or vice versa. but i did as you say and - as
expected - it does not work. see subject for failure message.

actually in the past few days i tried every qemu networking
configuration i could get my hands on. i tried -user-net and vde, i
fiddled with iptables, arp and tcpdump, masquerading, forwarding,
bridging, everything.
after manually filling all arp-caches with correct mac-adresses i can
even see icmp-packet coming out of the guest (with the ususal
WATCHDOG-failure, though). but the icmp-replys never show up in the
guest.
i think, the problem is, that every time network traffic is issued from
or to the guest, it does not work and these failure shows up
in /var/log/messages on the guest:

last hope for me was asking qemu devs on this list, but now i will try
one last thing. ditch the ubuntu-qemu and compile it myself.
