Buildbot Setup for Virtual Machines - Ubuntu 11.10 "oneiric"

Explains how to provision and configure virtual machine instances specifically for Buildbot testing.

Base Install

qemu-img create -f qcow2 /kvm/vms/vm-oneiric-amd64-serial.qcow2 8G
qemu-img create -f qcow2 /kvm/vms/vm-oneiric-i386-serial.qcow2 8G

# Start each VM booting from the server install iso one at a time and perform
# the following install steps:
kvm -m 1024 -hda /kvm/vms/vm-oneiric-amd64-serial.qcow2 -cdrom /kvm/iso/ubuntu-11.10-server-amd64.iso -redir tcp:2255::22 -boot d -smp 2 -cpu qemu64 -net nic,model=virtio -net user
kvm -m 1024 -hda /kvm/vms/vm-oneiric-i386-serial.qcow2 -cdrom /kvm/iso/ubuntu-11.10-server-i386.iso -redir tcp:2256::22 -boot d -smp 2 -cpu qemu32,-nx -net nic,model=virtio -net user

# Once running you can connect to the VNC server from your local host with:
#
#    vncviewer -via ${remote-host} localhost
#
# (replace ${remote-host} with the host the vm is running on)

# Install, picking default options mostly, with the following notes:
# * Set the hostname to ubuntu-oneiric
# * When partitioning disks, choose "Guided - use entire disk" (we do not want LVM)
# * No automatic updates
# * Choose software to install: OpenSSH server


# Now that the VM is installed, it's time to configure it.
# If you have the memory you can do the following simultaneously:
kvm -m 1024 -hda /kvm/vms/vm-oneiric-amd64-serial.qcow2 -cdrom /kvm/iso/ubuntu-11.10-server-amd64.iso -redir tcp:2255::22 -boot c -smp 2 -cpu qemu64 -net nic,model=virtio -net user -nographic
kvm -m 1024 -hda /kvm/vms/vm-oneiric-i386-serial.qcow2 -cdrom /kvm/iso/ubuntu-11.10-server-i386.iso -redir tcp:2256::22 -boot c -smp 2 -cpu qemu64 -net nic,model=virtio -net user -nographic

ssh -p 2255 localhost
# edit /boot/grub/menu.lst and visudo, see below

ssh -p 2256 localhost
# edit /boot/grub/menu.lst and visudo, see below

ssh -t -p 2255 localhost "mkdir -v .ssh; sudo addgroup $USER sudo"
ssh -t -p 2256 localhost "mkdir -v .ssh; sudo addgroup $USER sudo"

scp -P 2255 /kvm/vms/authorized_keys localhost:.ssh/
scp -P 2256 /kvm/vms/authorized_keys localhost:.ssh/

echo $'Buildbot\n\n\n\n\ny' | ssh -p 2255 localhost 'chmod -R go-rwx .ssh; sudo adduser --disabled-password buildbot; sudo addgroup buildbot sudo; sudo mkdir ~buildbot/.ssh; sudo cp -vi .ssh/authorized_keys ~buildbot/.ssh/; sudo chown -vR buildbot:buildbot ~buildbot/.ssh; sudo chmod -vR go-rwx ~buildbot/.ssh'

ssh -p 2256 buildbot@localhost 'sudo cp -vi ttyS0.conf /etc/init/; rm -v ttyS0.conf; sudo shutdown -h now'

Enabling passwordless sudo:

sudo VISUAL=vi visudo
# Add line at end: `%sudo ALL=NOPASSWD: ALL'

Editing /boot/grub/menu.lst:

sudo vi /etc/default/grub

# Add/edit these entries:
    GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 console=ttyS0,115200n8"
    GRUB_TERMINAL="serial"
    GRUB_SERIAL_COMMAND="serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1"

sudo update-grub

Install cmake (required for MariaDB 5.5) with:

kvm -m 1024 -hda ${vm} -redir tcp:22565::22 -boot c -smp 2 -cpu qemu64 -net nic,model=virtio -net user -nographic

ssh -o IdentityFile=.ssh/buildbot.id_dsa -p 22565 buildbot@localhost
