# Virtual machine creation and emulation

#
# HOW-TO:
# Put this on you /etc/network/interfaces
# if the real NIC in configured via dhcp:
#
# auto lo
# iface lo inet loopback
#
# auto eth1
#
# auto br0
# iface br0 inet dhcp
# bridge_ports eth1
#
# Put this on you /etc/network/interfaces if
# the real NIC in configured with and static IP:
#
# auto lo
# iface lo inet loopback
#
# auto eth1
#
# auto br0
# iface br0 inet static
# address 172.26.98.50
# netmask 255.255.248.0
# gateway 172.26.96.1
# bridge_ports eth1
#
#
# Then execute the following commands:
# cp qemu.sh ~
# apt-get install -y bridge-utils and kqemu-common kqemu-source
# cd /usr/src/
# bzip2 -d kqemu.tar.bzip2
# tar xvf kqemu.tar
# cd modules/kqemu
# ./configure && make && make install
# cd ~
# sudo ./qemu.sh

echo Moving display
export DISPLAY=:0.0
echo Loading acceleration kernel module
modprobe kqemu
echo Verifying hard disk image
if ! [ -f hda.img ]; then
echo Creating hda.img
qemu-img create hda.img 20G
fi
echo Verifying virtual net device
if ! [ -a /dev/net/tun ]; then
echo Creating /dev/net/tun
mknod /dev/net/tun c 10 200

echo To boot from a CD/DVD image or disk put
echo this on qemu options but one "-cdrom"
echo line showed bellow
echo -boot d \
echo -cdrom /dev/cdrom \
echo -cdrom cd.iso \
echo Starting VM emulation
qemu -m 256 \
-k es \
-net nic,vlan=0 \
-net tap,vlan=0,ifname=tap0 \
-hda hda.img \
-boot c \
-cdrom /dev/cdrom \
-usb \
-usbdevice "host:04a9:1900" \
-localtime &
echo Wainting VM boot and tap0 to appears
sleep 30s
echo Enabling tap0
/sbin/ifconfig tap0 0.0.0.0 promisc up
echo Adding tap0 to br0
/usr/sbin/brctl addif br0 tap0
