This subdirectory contains VM template configurations to be deployed on the OpenNebula platform.
An example is provided by opennebula_goera.tpl.
This template can and must be adapted according to the users needs. If renamed the path to the appropriate template must be set in the ClusterConf.ini config file.
Relevant sections that should be modified include
CONTEXT = [
DNS_HOSTNAME = "YES",
NETWORK = "YES",
SSH_PUBLIC_KEY = "replace_root_key",
USERNAME = "root",
GROUP = "eratosthenes-uu"]
The group should be changed to the user's. Note the SSH_PUBLIC_KEY is filled with a placeholder that filled by the automatically generated root public ssh key when using fully automatic deployment. Should the user wish deploy more manually this field can/should be modified.
DISK = [
DATASTORE = "local_images_ssd",
DATASTORE_ID = "104",
IMAGE_ID = "25621",
SIZE = "15360",
TYPE = "fs"]
This specifies the OS disk. The user MUST ensure that a base image (e.g. and Ubuntu server) exists in the specified datastore of the OpenNebula Platform with the specified IMAGE_ID. The size corresponds to the OS partition.
DISK = [
DATASTORE = "ceph",
DATASTORE_ID = "106",
FORMAT = "raw",
SIZE = "71680",
TARGET = "vdb",
TYPE = "fs" ]
This section specifies the local HDD of the VM.
DISK = [
DATASTORE = "local_system_ssd",
DATASTORE_ID = "103",
DISK_TYPE = "FILE",
SIZE = "49152",
TARGET = "vdc",
TYPE = "swap"]
This section defines a swap partition.
MEMORY = "32768"
MEMORY_UNIT_COST = "MB"
This specifies the VM's RAM allocation, anmd finally the following defines it's network connection. NETWORK and NETWORK_UNAME can be adpated, but this is not required.
