Configurare Buildbot per le Macchine Virtuali - Ubuntu 9.04 amd64

Installazione base

qemu-img create -f qcow2 vm-jaunty-amd64-serial.qcow2 8G
kvm -m 1024 -hda vm-jaunty-amd64-serial.qcow2 -cdrom /kvm/ubuntu-9.04-server-amd64.iso -redir tcp:2227::22 -boot d -smp 2 -cpu qemu64 -net nic,model=virtio -net user

Porta seriale e login/sudo senza password

kvm -m 1024 -hda vm-jaunty-amd64-serial.qcow2 -cdrom /kvm/ubuntu-9.04-server-amd64.iso -redir tcp:2227::22 -boot c -smp 2 -cpu qemu64 -net nic,model=virtio -net user

sudo apt-get install emacs22-nox

Aggiungere a /boot/grub/menu.lst:

serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=3 serial console

Aggiungere in menu.lst alla riga del kernel (cancellando `quiet splash'):

console=tty0 console=ttyS0,115200n8

Creare /etc/event.d/ttyS0:

# ttyS0 - getty
#
# Questo servizio mantiene un getty su ttyS0 dal punto in cui il sistema
# viene avviato fino all'arresto.

start on stopped rc2
start on stopped rc3
start on stopped rc4
start on stopped rc5

stop on runlevel 0
stop on runlevel 1
stop on runlevel 6

respawn
exec /sbin/getty 115200 ttyS0

Aggiungere un account e permettere sudo senza password:

sudo adduser --disabled-password buildbot
sudo adduser buildbot sudo
sudo EDITOR=emacs visudo
# decommentare `%sudo ALL=NOPASSWD: ALL' line in `visudo`, and move to end.

sudo su -s /bin/bash - buildbot
mkdir .ssh
cat >.ssh/authorized_keys
# Paste public key for buildbot user on host system.
chmod -R go-rwx .ssh
# Do manual login from host to guest once, to make sure .ssh/known_hosts is updated.

qemu-img create -b vm-jaunty-amd64-serial.qcow2 -f qcow2 vm-jaunty-amd64-build.qcow2
kvm -m 1024 -hda vm-jaunty-amd64-build.qcow2 -cdrom /kvm/ubuntu-9.04-server-amd64.iso -redir tcp:2227::22 -boot c -smp 2 -cpu qemu64 -net nic,model=virtio -net user -nographic

sudo apt-get build-dep mysql-server-5.1

Le VM per testare l'installazione

qemu-img create -b vm-jaunty-amd64-serial.qcow2 -f qcow2 vm-jaunty-amd64-install.qcow2
