Ever get tired of the same old virtual machine icons in the vSphere Client? Ever thought about changing it? Well with vSphere 5, you can! Here is a screenshot of some the custom icons I added for several virtual machines in my development lab.
One of the major enhancement in the vSphere 5 API is the introduction of the vCenter Solutions Manager, vSphere ESX Agent Manager, and vServices SDK. These various interfaces allows ISVs, partners and end users to easily extend the functionality of the vCenter Server and provide solutions that are tightly integrated via extensions/plugins that are aware of features such as vSphere HA, DRS and DPM.
Here what each of the interfaces provides:
You will need access to either the vCLI or vMA and the following two vSphere SDK for Perl scripts: registerCustomSolution.pl and updateVMManagedBy.pl You will also need access to vCenter Server 5 as this is not supported on an ESXi 5 host.
There is a very simple example in registerCustomSolution.pl which creates two extensions: one that includes custom icons and tabs that can link to any webpage (vGhetto) and one that only includes custom icons (Custom Application). You will need to edit the script so it fits your environment and there is a special variable in the script called "editedScript" which is set to 0 that prevents the script from running. This will ensure you do not accidentally create these extensions based on information in my development environment. Once you have updated the script, go ahead and change the value to a 1.
When you are ready, you will use the registerCustomSolution.pl script to create the extensions, here is an example:
To verify that the extensions were created properly with the information you provide, you can use pluginExtensionManager.pl to list all registered extensions. The command is the following: ./pluginExtensionManager.pl --operation list
You should see at the bottom of the output the extensions that were just registered and the associated configurations URL + icons. It is important to make note of the extension key (e.g. com.vmware.vGhetto) and the solution type string as that will be needed in the next section.
To verify the icons have been updated, you will need to login to the vCenter Server and check out your virtual machines.You will also notice that on the right hand side of the virtual machine summary screen, there is a new "Managed By" section which includes a link to the vCenter Solution Manager.
Note: If you would like to reset or revert back to the original icons, you just need to use the updateVMManagedBy.pl script and specify a empty string for the key. If you would like to unregister and remove the extension all together, you can use pluginExtensionManager.pl and perform remove operation.
Another way to view all the vCenter Solutions is on the home page and by clicking on the vCenter Solutions Manager icon.
From here you will see all registered vCenter extensions including some information about the vendor, version and health of the extension.
Here is a drill down into one of the extensions that contains several tabs to some URLs
As you can see, you can link to some useful URLs that can easily be accessible through the vSphere Client without having to go to your browser. Another neat feature of the tabs is to include any web management interfaces for a particular solution/vApp so that you can easily configure and manage the system from a single pane of glass.
In addition to this, you can also get a summary of the registered virtual machines with a given solution by clicking on the "Virtual Machines" tab and selecting "Managed By" box, the "Server" and "Agents" are reserved for ESX Agents.
There are also two caveats to be aware of if you decide to create custom icons for your virtual machines. The first is when you edit a virtual machine, you will get an annoying pop-up that states changes to the solution is not recommended. Under normal circumstance, where a solution/extension is provided by a 3rd party, you definitely do not want to manually tweak the virtual machine but in this scenario, it is fine.
The second thing I noticed is the custom icons do not properly show up in the nextgen vSphere Web Client, a default icon is used instead for virtual machines who have custom icons. I am not sure if this is a display bug with the vSphere Web Client or with the APIs.
So there you have it, if you are bored at looking at the same old icons and would like to differentiate some or all of your virtual machines, you now have the option to use custom icons.
Would it be cool if you can manage to distinguish between red hat and windows virtual machines and appy exact icon image as reference. Any tips? Azn2kew
That is pretty trivial using the vSphere API, you can figure out what guestOS it's been configured and create a mapping of icons to each of the guestOS types and then map that to each VM. You can even automate this once a week for any newly created VMs
