  6. Create a new qcow2 image

     $> qemu-img create -f qcow2 openvswitch.qcow2 100M

  7. Boot TinyCore

     $> kvm -hda openvswitch.qcow2 -cdrom CorePlus-current.iso -boot d -m 200
  • Select default boot mode
  1. Install TinyCore
  • Select installer from bottom menu
  • 1st screen: "Frugal", "Whole disk", "sda"
  • 2nd screen: "ext4"
  • 3rd screen: "kmap=qwertz/de-latin1-nodeadkeys superuser"
  • 4th screen: "Core only", "Non-US keyboard layout support"
  • Shutdown TinyCore after installation

  1. Boot installed system

     $> kvm -hda openvswitch.qcow2 -m 100

  2. Install some usefull packets

     KVM:$> cd /root; sudo su tc
 KVM:$> tce-load -wi nano dropear openssl-1.0.0 net-tools ipv6-3.8.13-tinycore
 KVM:$> scp USER@HOST:PATH/{openvswitch,bridge-utils,tunctl}.tcz* /mnt/sda1/tce/optional
 KVM:$> echo >> /mnt/sda1/tce/onboot.lst <<EOF
 tunctl.tcz
 bridge-utils.tcz
 openvswitch.tcz
 EOF

  3. Create a startup script

     KVM:$> cat > /opt/localboot.sh <<EOF
 #!/bin/sh
 # put other system startup commands here
 modprobe openvswitch
 modprobe 8021q
 modprobe ipv6
 export PATH="$PATH:/usr/local/sbin:/usr/local/bin"
 if ! [ -f /usr/local/etc/openvswitch/conf.db ]; then
   ovsdb-tool create
 fi

 ovs-vsctl --no-wait init
 ovs-vswitchd --pidfile --detach
 sysctl -w net.ipv4.ip_forward=1
 sysctl -w net.ipv6.conf.all.forwarding=1
 if ! $(ovs-vsctl list-br | fgrep br0 >/dev/null); then
   ovs-vsctl add-br br0
   for path in /proc/sys/net/ipv4/conf/eth*; do
     iface=$(basename $path)
     ovs-vsctl add-port br0 $iface
   done
   ovs-vsctl set-controller br0 ptcp:6633
 fi
 EOF
 filetool.sh -b
 halt

  4. Compress the image

     $> qemu-img convert -c -O qcow2 openvswitch.qcow2 openvswitch-compressed.qcow2
