recipe #326, HowTo: Install instance from cdrom

• find or create the MAC of the VM, 52:54:ee:9d:1a:10 in this case
• define dns/dhcp/nagios/proxy etc. (out of the scope of this page)
• make iso available on all nodes (or at least ganeti master, instance primary)
• Try :

• When add is done, use gnt-instance info to see which port vnc is bound to, and connect to vnc.
• The network must be configured manually because older/simpler DHCP clients are confused when the default route is not on the same subnet as the IP address of the VM
  • IP : 10.10.1.XXX
  • netmask : 10.10.0.0/16
  • gateway : 10.10.0.254
  • DNS : 10.10.0.254
• If the installer fails, try the following in a shell:
  • ip link set eth0 up
  • ip addr add 10.10.1.XXX dev eth0
  • route add -net 10.10.0.0 netmask 255.255.0.0 dev eth0
  • route add default gw 10.10.0.254
  • echo nameserver 10.10.0.254 > /etc/resolv.conf
• After installation, the DHCP client installed for Debian lenny or squeeze can handle the answer from the DHCP server and the interface must be changed from static to dhcp in /etc/network/interfaces
• After reboot, the cdrom is eject and it will not boot, the following must be done:
  • gnt-instance modify -H boot_order=disk redmine.pokersource.vm.gnt
  • gnt-instance reboot redmine.pokersource.vm.gnt
