• create the instance :
  • declare dns if not already declared
  • declare dhcp if not already declared
  • on ganeti master :

    for i in 1 3 4 5 6 7 8 9 10 11 12;do echo z2-$i && ssh z2-$i "cd /etc/dhcp3 && hg pull -u && /etc/init.d/dhcp3-server restart && rm /var/cache/bind/* && /etc/init.d/bind9 restart";done
    

  • on ganeti master :

    gnt-instance add --no-start -t drbd -s 10G -B memory=128m --no-start -n z2-X.host.gnt:z2-Y.host.gnt -o debootstrap --net 0:mac=XX:XX:XX:XX:XX:XX yourvm.vm.gnt
    

  • on ganeti master :

    gnt-instance activate-disk yourvm.vm.gnt
    

It will answer with something like :

z2-X.host.gnt:/dev/drbdYY

• on z2-7.host.gnt (the result of previous command) :

  gzip -c your_vm_image.gz | ssh z2-X.host.gnt "dd of=/dev/drbdYY
  

• on ganeti master :

  gnt-instance deactivate-disk yourvm.vm.gnt
  gnt-instance start yourvm.vm.gnt
