Create new VM on Machine/justice or Machine/freedom

This procedure creates a clone of the Ubuntu Xenial template virtual machine.

virt-clone -o template-xenial --file=/var/lib/libvirt/images/boot/FOOBAR-boot.img --file=/dev/justice/FOOBAR-root -n FOOBAR
virsh autostart FOOBAR
virsh start --console FOOBAR
  • Add A and AAAA records for the new host in the sugarlabs.org zone file (See Service/Nameservers).
  • Now login as root from the console (there should be no password)
  • setup both IPv4 and IPv6 addresses
vi /etc/network/interfaces
  • change machine fqdn
sed -i -e s/template-xenial/FOOBAR/g /etc/hosts /etc/hostname /etc/mailname /etc/postfix/main.cf
  • activate new IP and hostname
/etc/init.d/networking restart
  • install latest security/stability updates
apt-get update
apt-get dist-upgrade
  • Find a nice color combo for HOST_COLOR in /etc/zzz_profile.conf
  • generate host keys and a key for root
rm /etc/ssh/ssh_host_*
dpkg-reconfigure openssh-server
ssh-keygen -N "" -f /root/.ssh/id_rsa -t rsa
  • Move daily, weekly, monthly cronjobs to a unique timeslot to avoid cpu/net storms
vi /etc/crontab
  • The most important thing: come up with a funny quip for this machine
vi /etc/motd.tail
  • Taa--daah!
reboot
[FOOBAR.sugarlabs.org]
       address FOOBAR.sugarlabs.org
