Hi Gabriel,
Thanks. Your post reminded me to have a look. This the set up I used a
while ago ..
qemu-system-arm \
-M xilinx-zynq-a9 -m 256M -no-reboot -serial null \
-serial mon:stdio -nographic -net nic,model=cadence_gem \
-net vde,id=vde0,sock=/tmp/vde1 -kernel $*
This use the vdeswitch package. The RSB will build VDE support into qemu
if it is installed and available.
On FreeBSD I have a bridge with a tap interface. The /etc/rc.conf has ...
cloned_interfaces="bridge0 tap0"
autobridge_interfaces="bridge0"
ifconfig_bridge0="inet 10.1.1.2 netmask 255.255.255.0"
autobridge_bridge0="re0 tap0"
ifconfig_re0="up"
ifconfig_tap0="up"
defaultrouter="10.1.1.1"
Then run the VDE switch with ...
#! /bin/sh
#
# vdeterm /tmp/mgmt1
#
sysctl net.link.tap.user_open=1
sysctl net.link.tap.up_on_open=1
chmod 660 /dev/tap0
vde_switch -d -s /tmp/vde1 -M /tmp/mgmt1 -tap tap0 -m 660 \
--mgmtmode 660
VDE lets me run a number of qemu sessions together and have them see
each other without needing to add a bunch of tap interfaces.

Hi Joel,
Before running qemu, some qtabs should be created. How to do that it is
described on file libbsd.txt (line 333). Then I usually run qemu as follows:
qemu-system-i386 -append --console=/dev/com1 -no-reboot -serial stdio
-monitor none -nographic -netdev
tap,ifname=qtap1,script=no,downscript=no,id=n1 –device
e1000,netdev=n1,mac=52:55:00:d1:55:01 -kernel path/to/exe/file
Please note that if you are running two instances, the second one should
have different MAC address and ifname, e.g. mac=52:55:00:d1:55:0*2*and
ifname=qtab*2*
**
If hope this helps.
Cheers,
Gabriel

Hi
Does someone have a qemu command line handy for running libbsd network
applications on Qemu?
I have lots of notes and old examples but can't seem to trip the right
combination today.
Thanks.
