Create new VM on Machine/treehouse

virsh vol-create-as treehouse FOOBAR 10G
virt-clone -o template-jaunty --file=/dev/treehouse/FOOBAR -n FOOBAR
virsh start --console FOOBAR

Login using the default root password (ask bernie), then setup the machine:

# change root password
passwd root

# setup both IPv4 and IPv6 addresses (remember to update zone files)
vi /etc/network/interfaces

# change machine fqdn
sed -i -e s/template-jaunty/FOOBAR/ /etc/hostname /etc/postfix/main.cf

# activate new IP and hostname
service networking restart

# install latest security/stability updates
aptitude update
aptitude full-upgrade

# generate host keys and a key for root
ssh-keygen -q -N "" -f /etc/ssh/ssh_host_rsa_key -t rsa
ssh-keygen -q -N "" -f /etc/ssh/ssh_host_dsa_key -t dsa
ssh-keygen -q -N "" -f /root/.ssh/id_rsa -t rsa
  • Install /root/.ssh/id_rsa.pub key on sugarbackup@backup.sugarlabs.org
# setup backups
vi /etc/system-full-backup.conf

# log in for the first time on backup server to accept ssh fingerprint
ssh sugarbackup@backup.sugarlabs.org

# the most important thing: come up with a funny quip for this machine
vi /etc/motd.tail

# taa--daah!
reboot
