Taking OpenNebula for a Test Drive

There are a couple of very easy ways to try out the OpenNebula functionality

• miniONE for infrastructures based on open source hypervisors.
• vOneCloud for VMware based infrastructures.

Installation

You can find more information about OpenNebula’s architecture, installation, configuration and references to configuration files in this documentation section.

It is very useful to learn where log files of the main OpenNebula components are placed. Also check the reference about the main OpenNebula daemon configuration file.

Front-end Installation

The Front-end is the central part of an OpenNebula installation. This is the machine where the server software is installed and where you connect to manage your cloud. It can be a physical node or a virtual instance.

Please, visit the official documentation for more details and a step-by-step guide. Using the packages provided on our site is the recommended method, to ensure the installation of the latest version, and to avoid possible package divergences with different distributions. There are two alternatives here: you can add our package repositories to your system, or visit the software menu to download the latest package for your Linux distribution.

If there are no packages for your distribution, please check the build dependencies for OpenNebula and head to the Building from Source Code guide.

Node Installation

After the OpenNebula Front-end is correctly set up, the next step is preparing the hosts where the VMs are going to run. Please, refer to the documentation site for more details.

tm_ssh with local image cache

Hello,

For cases when main image for VM does not change (it's cloneable) caching it locally on host can provide significant reduction in network traffic and reduce VM startup time. Please consider attached patch that provides new TM: tm_ssh_cache. tm_ssh_cache reuses most scripts from tm_ssh with the notable exception of tm_clone.sh that supports caching image file locally on each host in /nebula/image-cache/ directory.

This covers all the resources:

• Test that the host is up and ssh reachable before creation
• Test the network has the right bridge in the host
• Check that the datastore refers to a proper data source

The above needs to span across clusters, ie, when a datastore is added to a cluster, all the hosts belonging to the cluster need to mount the datastore.

Maybe a --force option can be fined to bypass the tests

From a mail by Hans-Joachim Ehlers (http://lists.opennebula.org/pipermail/users-opennebula.org/2013-February/022188.html):

For automation it would be nice to have a defined output format support by an additional option like "-F | --format"

Where format could be : stanza , xml , {}  or what ever is useful and reliable. Might ease command output handling .

Example:
 --format S # Stanza

ServiceComponent:
    Service=<service_name>
    Name=<component_name>
    Module=<module_name>
    ComponentDataSize=<size>


 --format X # XML
<ServiceComponent>
...
</ServiceComponent>

Format selection should be selectable using a single parameter. "--format" seems a good candidate.

Include cpu tune & topology parameters for qemu/libvirt drivers

Author Name: Ruben S. Montero (@rsmontero)
Original Redmine Issue: 796, https://dev.opennebula.org/issues/796
Original Date: 2011-09-06

This ticket is to match the CPU parameter with the new cputune attributes of libvirt. Xen drivers update the ticket-based scheduler to distribute physical cpu cycles among VMs (So VMs with higher CPU values will get more physical CPU). This new feature will level the KVM driver with the Xen one in this area.

Also we may include CPU-pin attributes. The Xen driver could implement this trough the hwloc utility

The aim of this feature is to be able to dynamically add/remove vCPU's and increase/decrease the memory of a running virtual machine.

The patch was initially posted on the mailing list and was developped by Paul Grandperrin (http://www.mail-archive.com/[email protected]/msg05504.html)

The attached patch is the really same patch but updated for OpenNebula 3.4. It does not include the remarks made by Carlos Martín Sánchez yet - this has still to be implemented.

The patch adds a 'vcpuset' and a 'memset' parameter to the 'onevm' command. Right now, only the Xen backend is implemented.

Add support for "Console Output"

---

Author Name: Ricardo Duarte (Ricardo Duarte)
Original Redmine Issue: 1710, https://dev.opennebula.org/issues/1710
Original Date: 2012-12-31

Some hypervisors (KVM, Xen) support dumping the console output to a file.
The console output includes the boot sequence output.
OpenNebula can easily be extended to make the file available from CLI, Sunstone and Self-service, by using the same functionality that supports the "VM Log" tab.
Changes required would be:

• Add the option for console output to the "new" template form, and translate that into hypervisor specific configuration
• Add a "Console Output" tab to the virtual machine details
• Create a get-console-output CLI action

This will then be used to implement the GetConsoleOutput EC2 action.

To grow to a larger community, OpenNebula must support also Hyper-V on its infrastructure and migrate.
Besides the update of Hyper-V drivers from 3.2 to 3.8, it should be native and not optional on ecosystem.

A faster feature to implement is being able to import VHD files to ONE, just with an additinal qemu-img convert -f vpc -O raw on image register.

It would be great to be able to customize some drop/down lists. Those lists would be used to prefill text fields. So user still have the possibility to fill those fields by hand.

Dear Developers,

we have developed an ATA-over-Ethernet storage driver set for the OpenNebula. It should perform better in small and medium ethernet networks than iSCSI (however it is less secure). Our tests shows 35-60% better throughput and latency. VM deploy and migration times are also faster. The driver is based on the iSCSI driver set, basically the tgt daemon was replaced with vblade and vblade-persist software package.
Feel free to include it in the mainline opennebula or in the ecosystem.

• oneimage disable or delete simply says "Could not disable/delete image", when the reason is that the Image is in the USED state
• There are some operations, like a onevm stop, that log return codes in oned.log without loggin the operation that returned it: [TM][D]: Message received: LOG I 22 ExitCode: 0
• VirtualMachineManagerDriver.cc uses Log::ERROR to log successful actions

Hi,

In datastore/rm script, I use error_message function to notify user something went wrong. The problem is nothing is shown in Sunstone. Moreover, if something went wrong, the image record is dropped from DB regardless rm script exit status.

The second part is more a feature request. I would like to see "recoverable actions" implemented in OpenNebula.
When there is non fatal error, user would have the possibility to retry action later. For example, with datastore/rm script, I have to do some checks on SAN before removing volume. If for some reason (bad status...) it is not possible to remove the volume, the action is aborted and the user could retry it later. We could use specific exit status from drivers to detect this.

Regards,

Laurent

The idea is to have the current oned.conf file split in multiple configurations files that can be loaded and there is no need to modify the oned.conf (eg. adding a new driver would be as simple as copying a file into the directory)

• Make oned.conf a directory oned.conf.d in etc
• Make oned able to load each file

This feature would provide an ssh console for managing VMs.

Sunstone -> Virtual Machines, page:
Add an icon next to the noVNC connect icon that symbolizes an SSH remote login.
Each VM image would be prepared with an ssh public key to allow sunstone to connect to the VM.
The connection would be displayed in an interactive textera form element, or similar.

I am sure someone has come up with a way to run SSH sessions from a web page.

Possible benifits:

• Eease of administrative access to the host OS of each VM.
• Internode operability.
• Less network bandwidth intensive than running a VNC session when all you need is text.

The idea is to compliment the VNC session as and not to replace it.

Hello,

this is a new authentication system for OpenNebula Sunstone, it is designed to work with SimpleSAMLphp, and so the authentication of the users is SAML-federated. On the IDP side you can either use SimpleSAMLphp or other SAML-based software as well. We are using this solution within our institute together with Virtual Organization Management software. Since we have introduced this system user management become much easier.

This authentication system contains an OpenNebula patch, and two standard SimpleSAMLphp modules. The OpenNebula extension part of the patch based on the XML-RPC API, and works together with SimpleSAMLphp SP. When a user authenticated in SimpleSAMLphp, it transfers an attribute, which informs the OpenNebula authentication module about the user's group. This method allows the user to belong to more groups, and its group can be switched at the login.

Features:

• simplified login with SAML
• users can belong to more groups

More info at: "SSP for OpenNebula homepage":http://ssp-for-opennebula.sztaki.hu/

We hope this will be as useful for others as it is for us.
