[one-users] SaaS with opennebula cloud

[biro lehel]

I'll just put this on the list, it seems like Daniel is busy, but maybe someone else can help me with an answer.

Thank you in anticipation,
Lehel.


Daniel, two more things..

When creating a new occi template, can I use as IMAGE_ID an ID of an existing peristent image (of course one that is not currently USED)? 
At the moment I have some persistent images, from which I configured and set-up VM's with some specific software (I'm working on building a kind of "platform" above the "infrastructure"), and I intend these VM's to be used by end-users. In my original templates (that are using the persistent images), besides the image disk definition, I had some further disks defined (type FS and SWAP). Would these disks be available if I pass only the persistent image ID in my new_occi_template.erb? I mean, would I get "the very same VM back"?

Also, I read that Self Service currently supports only ranged networks. Does this mean that there is no way to set for a specific VM a specific IP
 address?

Thank you in anticipation,
Lehel.

 OpenNebula account, but at the same time not being aware of this)?


OpenNebula Self-Service is a simplified GUI aimed to end-users,
offering a simplified access to shared infrastructure for non-IT end
users.

The administrator will configure a set of instance_types that the
end-user will be able to select without taking care of the VM
configuration. The user can login to this portal and interact with his
resources.

The VirtualNetworks and Images can be exposed in three different ways:
1. The administrator creates the VNETs and Images through the one*
tools and distributes these resources in different instance_types. The
end-user will just have to select the desired instance_type

$ onevnet create occi_vnet
ID: 2
$ oneimage create occi_image
ID:3
$ cat $ONE_LOCATION/etc/occi_templates/new_occi_template.erb
CPU=1
MEMORY=1024
DISK=[IMAGE_ID=3]
NIC=[NETWORK_ID=2]
$ cat
 $ONE_LOCATION/etc/occi.conf
[...]
:instance_types:
  [...]
  :new_occi_template:
    :template: new_occi_template.erb
    :cpu: 1
    :memory: 1024


2. The administrator creates the VNETs and Images through the one*
tools and makes them available for the end-user. The end-user selects
which instance_type he wants to use and what image and network
throught the GUI interface.

$ onevnet create occi_vnet
ID: 2
$ oneimage create occi_image
ID:3
$ cat $ONE_LOCATION/etc/occi_templates/new_occi_template.erb
CPU=1
MEMORY=1024
$ cat $ONE_LOCATION/etc/occi.conf
[...]
:instance_types:
  [...]
  :new_occi_template:
    :template: new_occi_template.erb
    :cpu: 1
    :memory: 1024

3. The end-user is allowed to create VNETs (you can also define a base
template for this) and upload Images and
 can select them for a new
instance through the GUI interface

$ cat $ONE_LOCATION/etc/occi_templates/new_occi_template.erb
CPU=1
MEMORY=1024
DISK=[IMAGE_ID=3]
NIC=[NETWORK_ID=2]
$ cat $ONE_LOCATION/etc/occi.conf
[...]
:instance_types:
  [...]
  :new_occi_template:
    :template: new_occi_template.erb
    :cpu: 1
    :memory: 1024

If you want to enable VNC you have to add the following line to the templates:
GRAPHICS = [
  TYPE    = "vnc",
  LISTEN  = "0.0.0.0",
  PORT    = "5"]

Hope this helps

> hi, we have developed the opennebula cloud with front end and 5 worker nodes , we can successfully create the VM and can deploy them on the worker nodes.Hence we are able to run the windows as well as linux on the dom U of the worker nodes(using XEN) . We are using centos 5.0 on the worker nodes as the host os.We can also manage using Sunstone GUI.

 yes then what configuration is left ? , please guide us on that .
