Sysadmin/Add virtual machine

Create new VM on Machine/justice or Machine/freedom

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

virt-clone --prompt -o template-precise --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-precise/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

aptitude update
aptitude full-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

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

Add the machine to /etc/munin/munin.conf on Machine/sunjammer for monitoring.
