=== Create new VM on [[Machine/treehouse]] ===
=== Create new VM on [[Machine/justice]] or [[Machine/freedom]] ===
This procedure creates a clone of the [[Machine/template-xenial|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
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
ssh-keygen -q -N '' -f /etc/ssh/ssh_host_dsa_key -t dsa
rm /etc/ssh/ssh_host_*
dpkg-reconfigure openssh-server
ssh-keygen -N "" -f /root/.ssh/id_rsa -t rsa
* Setup wizbackup on a backup server (See [[Service/backup]])
* 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
reboot
* Add the machine to <code>/etc/munin/munin.conf</code> on [[Machine/sunjammer]] for monitoring.
