Node roles

Each node can be in one of the following states:

master

Only one node per cluster can be in this role, and this node is the one holding the authoritative copy of the cluster configuration and the one that can actually execute commands on the cluster and modify the cluster state. See more details under Cluster configuration.
master_candidate

The node receives the full cluster configuration (configuration file and jobs) and can become a master via the gnt-cluster masterfailover command. Nodes that are not in this state cannot transition into the master role due to missing state.

regular

This the normal state of a node.

drained

Nodes in this state are functioning normally but cannot receive new instance, because the intention is to set them to offline or remove them from the cluster.

offline

These nodes are still recorder in the ganeti configuration, but except for the master daemon startup voting procedure, they are not actually contacted by the master. This state was added in order to allow broken machines (that are being repaired) to remain in the cluster but without creating problems.

Rather than invoking init scripts through /etc/init.d, use the service(8)

Since the script you are attempting to invoke has been converted to an

# ganeti-instance-debootstrap defaults file

# if you want to change from the default of installing debian stable
# on the next instance, customize this file before the instance
# installation

# PROXY: if non-null, use this as an http-proxy in order to speed up
# non-cached installs; not that if not set, debootstrap might still
# use a system-wide proxy setting if it is exported in the
# ganeti-noded daemon environment
# PROXY="http://proxy.example.com:3128/" 

# MIRROR: do not customize MIRROR if you want to be able to install
# both debian and ubuntu, since they have different defaults; or
# customize it before each install
MIRROR="http://archive.bring.out.ba/ubuntu" 

# ARCH: define ARCH only if you want a different architecture than the
# current one; the known use case is to install a 32-bit instance on a
# 64-bit node; choose either "i386" or "amd64":
# ARCH="i386" 
ARCH="amd64" 

# SUITE: change suite to any of the ones supported by deboostrap; this
# could be unstable, etch, etc.:
# SUITE="lenny" 
SUITE="lucid" 

# EXTRA_PKGS: depending on the suite and architecture you are using, different
# extra packages are needed for different hypervisors. For example:
#
# Xen, for etch/lenny i386:
# EXTRA_PKGS="linux-image-xen-686,libc6-xen" 
# Xen, for etch/lenny amd64:
# EXTRA_PKGS="linux-image-xen-amd64" 
# KVM, for lenny i386:
# EXTRA_PKGS="acpi-support-base,console-tools,udev,linux-image-686" 
# KVM, for lenny amd64:
# EXTRA_PKGS="acpi-support-base,console-tools,udev,linux-image-amd64" 
#

# CUSTOMIZE_DIR: a directory containing scripts to customize the installation.
# The scripts are executed using run-parts
# By default /etc/ganeti/instance-debootstrap.d
# CUSTOMIZE_DIR="/etc/ganeti/instance-debootstrap.d" 

# GENERATE_CACHE: if set to yes (the default), create new cache files;
# any other value will disable the generation of cache files (but they
# will still be used if they exist)
GENERATE_CACHE="yes" 

# CLEAN_CACHE: should be set to the number of days after which to
# clean the cache; the default is 14 (two weeks); to disable cache
# cleaning, set it to an empty value ("")
CLEAN_CACHE="14" 

# PARTITION_STYLE: whether and how the target device should be partitioned.
# Allowed values:
# 'none': just format the device, but don't partition it
# 'msdos': install an msdos partition table on the device, with a single
#          partition on it
# (more styles may be added in the future)
# The default is "msdos" from ganeti 2.0 onwards, but none if installing under
# Ganeti 1.2 (os api version 5)
# PARTITION_STYLE="none"

I used the following command to create a single kvm instance using a lenny iso:

# gnt-instance add -H kvm:boot_order=cdrom,cdrom_image_path='<ISO-FILE-PATH>',kernel_path='',initrd_path='', \
root_path=/dev/vda1,disk_type=ide,vnc_bind_address=0.0.0.0 -t
plain --disk 0:size=<SIZE> -B memory=<MEM> -o debootstrap -n <NODE> <INSTANCE>

I don't know if it is the best approach but it worked for me.

Most of the options where taken from PrimeHaxor's (thanks) email: KVM CD Images.
