Here is how to make an unattended installation ISO of Ubuntu 14.04 Server.

Reference

http://pricklytech.wordpress.com/2013/04/21/ubuntu-server-unattended-installation-custom-cd/

make automatic installation ISO

mount the ISO

# mount -o loop /home/hattori/ISO_files/ubuntu-14.04-server-amd64.iso /home/hattori/iso

copy files to /home/hattori/serveriso directory

# cp -rT /home/hattori/iso /home/hattori/serveriso

# chmod -R 777 /home/hattori/serveriso/

configure language ( in my case, use japanese )

first search supported language from langlist file and configure language you want to use

# cd /home/hattori/serveriso/isolinux/

# grep ^ja langlist

# echo ja > langlist

# cat langlist

install system-config-kickstart to make a kickstart file.

# apt-get install system-config-kickstart

start.

error.

# system-config-kickstart

Traceback (most recent call last):

File "/usr/share/system-config-kickstart/system-config-kickstart.py", line 92, in <module>

kickstartGui.kickstartGui(file)

File "/usr/share/system-config-kickstart/xconfig.py", line 115, in fill_driver_list

raise RuntimeError, (_("Could not read video driver database"))

RuntimeError: ビデオドライバーのデータベースを読み込むことができませんでした

Googling this, this seems to be a bug.

follow the instructions.

# apt-get remove hwdata -y

Reading package lists... Done

The following package was automatically installed and is no longer required:

localechooser-data

Use 'apt-get autoremove' to remove it.

The following packages will be REMOVED:

hwdata system-config-kickstart

# wget ftp://mirror.ovh.net/mirrors/ftp.debian.org/debian/pool/main/h/hwdata/hwdata_0.234-1_all.deb

# dpkg -i hwdata_0.234-1_all.deb

# apt-get install system-config-kickstart -y

start. Okay.

# system-config-kickstart

make an ISO

# cd /home/hattori/serveriso/

# file /home/hattori/ubuntu1404_auto.iso

/home/hattori/ubuntu1404_auto.iso: # ISO 9660 CD-ROM filesystem data 'auto install' (bootable)

install ubuntu by using this ISO.

I confirmed that the the installation succeeds within KVM.

Here is how to install/configure openvswitch on Ubuntu 14.04 with single interface

- before installing openvswitch.

server eth0 --- the internet

- after installing open vswitch

VM1 vnet0 - ovsbr0p1 - ovsbr0 - eth0 --------- the internet

VM2 vnet1

VM3 vnetX

←---------------- server ----------------->

ovsbr0p1 : internal port

ovsbr0 : bridge

eth0 : uplink

vnetX : port for VMs

assign an IP to ovsbr0p1 for the KVM host to use the internet

The KVM host has only one NIC.

install openvswitch. assume that you have already installed KVM.

# apt-get install openvswitch-switch

[ configure network ]

add ovsbr0 bridge and destroy default network.

After issuing “ovs-vsctl add-br ovsbr0”, the network ovsbr0 has been automatically created in KVM. ( virsh net-list --all )

# ovs-vsctl add-br ovsbr0

# virsh net-destroy default

Network default destroyed

# ovs-vsctl show

undefine default network ( nat network ) and enable ovsbr0 network. ( open vswitch )

virsh # net-undefine default

connect bridge ovsbr0 to its uplink eth0

# ovs-vsctl add-port ovsbr0 eth0

add an internal port ovsbr0p1 connected to bridge ovsbr0

# ovs-vsctl add-port ovsbr0 ovsbr0p1 -- set interface ovsbr0p1 type=internal

edit /etc/network/interfaces.

assign an IP to ovsbr0.
