Sysadmin/Add virtual machine

Create new VM on Machine/treehouse

This procedure creates a clone of the Sysadmin/Template virtual machine.

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

• Add A and AAAA records for the new host in the sugarlabs.org zone file (See Sysadmin/Nameservers).

• To setup the machine, 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-lucid/FOOBAR/ /etc/hostname /etc/postfix/main.cf

# activate new IP and hostname
/etc/init.d/networking restart

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

# generate host keys and a key for root
ssh-keygen -N "" -f /etc/ssh/ssh_host_rsa_key -t rsa
ssh-keygen -N "" -f /etc/ssh/ssh_host_dsa_key -t dsa
ssh-keygen -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

# 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.
