FWIW, QEMU also has a built-in packet-dump functionality. You can use it
like this:

qemu-system-xxx ... -netdev user,id=netuser \
   -object filter-dump,id=dump,netdev=netuser,file=/tmp/dump.dat \
   -device e1000,netdev=netuser,mac=00:11:22:33:44:55

Then run "wireshark -r /tmp/dump.dat" afterwards to have a look at the
packets.
