Buildbot Setup for Virtual Machines - Ubuntu 11.10 "oneiric"

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

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

wget http://www.cmake.org/files/v2.8/cmake-2.8.6.tar.gz
tar -zxvf cmake-2.8.6.tar.gz
cd cmake-2.8.6;./configure
make
sudo make install

sudo /sbin/shutdown -h now
