 == Getting Started
 
-== Qemu
-
-Use the following script to set up a virtual network with three tap devices
-connected via one bridge device.
-
--------------------------------------------------------------------------------
-#!/bin/sh -x
-
-user=`whoami`
-interfaces=(1 2 3)
-
-tap=qtap
-bri=qbri
-
-case $1 in
-	up)
-		sudo -i brctl addbr $bri
-		for i in ${interfaces[@]} ; do
-			sudo -i tunctl -t $tap$i -u $user ;
-			sudo -i ifconfig $tap$i up ;
-			sudo -i brctl addif $bri $tap$i ;
-		done
-		sudo -i ifconfig $bri up
-		;;
-	down)
-		for i in ${interfaces[@]} ; do
-			sudo -i ifconfig $tap$i down ;
-			sudo -i tunctl -d $tap$i ;
-		done
-		sudo -i ifconfig $bri down
-		sudo -i brctl delbr $bri
-		;;
-esac
--------------------------------------------------------------------------------
-
-Connect your Qemu instance to one of the tap devices, e.g.
-
--------------------------------------------------------------------------------
-qemu-system-i386 -m 512 -boot a -cpu pentium3 \
-	-drive file=$HOME/qemu/pc386_fda,index=0,if=floppy,format=raw \
-	-drive file=fat:$HOME/qemu/hd,format=raw \
-	-net nic,model=e1000,macaddr=0e:b0:ba:5e:ba:11 \
-	-net tap,ifname=qtap1,script=no,downscript=no \
-	-nodefaults -nographic -serial stdio
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
-qemu-system-arm \
-	-serial null \
-	-serial mon:stdio \
-	-nographic \
-	-M xilinx-zynq-a9 \
-	-net nic,model=cadence_gem,macaddr=0e:b0:ba:5e:ba:11 \
-	-net tap,ifname=qtap1,script=no,downscript=no \
-	-m 256M \
-	-kernel build/arm-rtems5-xilinx_zynq_a9_qemu/media01.exe
--------------------------------------------------------------------------------
-
-Make sure that each Qemu instance uses its own MAC address to avoid an address
-conflict (or otherwise use it as a test).
-
-To connect the Qemu instances with your local network use the following
-(replace 'eth0' with the network interface of your host).
-
--------------------------------------------------------------------------------
-ifconfig eth0 0.0.0.0
-brctl addif qbri eth0
-dhclient qbri
--------------------------------------------------------------------------------

-=== VDE and QEMU
-
-On FreeBSD you can create VDE or the Virtual Distributed Ethernet to create a
-network environment that does not need to run qemu as root or needing to drop
-the tap's privileges to run qemu.
-
-VDE creates a software switch with a default of 32 ports which means a single
-kernel tap can support 32 qemu networking sessions.
-
-To use VDE you need to build qemu with VDE support. The RSB can detect a VDE
-plug and enable VDE support in qemu when building. On FreeBSD install the VDE
-support with:
-
- # pkg install -u vde2
-
-Build qemu with the RSB.
-
-To network create a bridge and a tap. The network is 10.10.1.0/24. On FreeBSD
-add to your /etc/rc.conf:
-
- cloned_interfaces="bridge0 tap0"
- autobridge_interfaces="bridge0"
- autobridge_bridge0="re0 tap0"
- ifconfig_re0="up"
- ifconfig_tap0="up"
- ifconfig_bridge0="inet 10.1.1.2 netmask 255.255.255.0"
- defaultrouter="10.10.1.1"
-
-Start the VDE switch as root:
-
- # sysctl net.link.tap.user_open=1
- # sysctl net.link.tap.up_on_open=1
- # vde_switch -d -s /tmp/vde1 -M /tmp/mgmt1 -tap tap0 -m 660 --mgmtmode 660
- # chmod 660 /dev/tap0
-
-You can connect to the VDE switch's management channel using:
-
- $ vdeterm /tmp/mgmt1
-
-To run qemu:
-
- $ qemu-system-arm \
-	-serial null \
-	-serial mon:stdio \
-	-nographic \
-	-M xilinx-zynq-a9 \
-	-net nic,model=cadence_gem,macaddr=0e:b0:ba:5e:ba:11 \
-	-net vde,id=vde0,sock=/tmp/vde1
-	-m 256M \
-	-kernel build/arm-rtems5-xilinx_zynq_a9_qemu/rcconf02.exe

 == Issues and TODO
 
 * PCI support on x86 uses a quick and dirty hack, see pci_reserve_map().
