How to connect to an ESX host using a SSH Client

This article details steps for connecting to an ESX host using an SSH Client. This video uses the PuTTY SSH Client, but a number of different clients work similarly. The steps in the video are the same for different versions of ESX, but for the video, we used ESX 4.

How to find your VMware product licenses on the Account Management portal

Our latest video details how to find your VMware product license key on the Account Management portal. As an example, you can find the product license key for your vSphere, VMware Fusion, VMware Workstation, VMware View, or VMware Lab Manager license. Further, the video provides steps for finding the serial number or serial key for legacy VMware products, like Virtual Infrastructure 3, or Lab Manager 2.

Note: You must be the Primary License Administrator or the Secondary License Administrator to view licenses for datacenter products. If you are the Support Administrator, you cannot manage licenses, however you can file a support request.

Running older versions of Virtual Machine Tools on newer versions of ESX hosts

We have received several requests from customers asking us to clarify our support status of running older versions of Virtual Machine Tools on newer versions of ESX hosts. To help clear up any confusion we are now stating this:

It is strongly recommended that the version of VMware Tools running in the VM match the version of ESX/ESXi on which the VM is running. It is also recommended that after ESX/ESXi is upgraded, that  VMware Tools in all the VMs on that host be upgraded at the earliest opportunity. VMware Global Support Services (GSS) will assist customers even if they have mismatched versions of Tools and ESX/ESXi, however GSS may require that the appropriate version of Tools be installed in the guest if GSS suspects that the mismatched version of Tools may be contributing to the issue being reported, if it makes debugging the issue easier or for any other reason.

Shared Folders

The shared folders feature provides a great way to share files between virtual machines and the host computer—you can designate folders on your computer that you can see and use from within your virtual machines. We occasionally get feedback from users who are having problems setting up and using shared folders. If you're having problems using shared folders, here are a few things to check:

VMware Toolbar chatroom- pure gold!

In just two days the new VMware Support Toolbar has been installed over 1,600 times by customers, tech support engineers, technical account managers, trainers, and more.

It is amazing to see the kinds of conversations going on in the chat room that comes standard with the toolbar.  Just look at this precious nugget of knowledge from Daniel on our Storage support team-

Daniel@VMware: http://kb.vmware.com/kb/1008205 is your friend in regards to storage performance.
Daniel@VMware: DAVG/cmd is the key one for performance issues outside of the VMKernel…
Daniel@VMware: As per the article… DAVG/cmd is the average response time in milliseconds per command being sent to the device is the average response time in milliseconds per command being sent to the device
Daniel@VMware: In regards to the size of HBA queues vs. the size of your Storage Controller Queues, it’s more difficult to troubleshoot or diagnose.
Daniel@VMware: most of those types of components are external to VMware ESX… we only see one side of the puzzle (HBA), so it’s a bit tricky.
Daniel@VMware: For sense codes, there is another article Interpreting sense codes KB 289902.  IT will tell you how to decode SCSI specific error messages.
Daniel@VMware: generally if it’s that bad, we rely of SCSI sense codes to tell us what’s going on at the SCSI layer…
Daniel@VMware: For sense codes, there is another article Interpreting sense codes KB 289902.  IT will tell you how to decode SCSI specific error messages.
nirvy: good stuff, cheers for that!
wondernerd: yes props for that!!!               

We hope Daniel spends more time in the chat room. 🙂

VMware Support Toolbar tips

Here’s a couple of tips for users of our new VMware support toolbar.

There are now two variations of the toolbar catering to different types of customers. Learn about the two different versions; one for the Datacenter crowd, and one for desktop virtualization users. They look very similar to one another, but the content is definitely different.

Also learn how to change the default search engine. We like setting this to search our KB and leaving it there, but you have the option.

VMware Toolbar Announcement

The Knowledgebase Team at VMware is happy to announce the immediate availability of a brand new browser toolbar:

 

VMware Support Toolbar

  • Instant access to patches, documentation, and more.
  • Built-in RSS and Twitter updates direct from Tech Support.
  • Live peer to peer chat lets you ask for help from other VMware experts and staff.
  • Custom search capabilities.
  • Works on IE, Firefox, Safari, and as of Feb 2011 Chrome.
  • No spyware; secure, safe, and private.

Another cool new capability the toolbar gives us is the ability to send a desktop alert to all customers with the toolbar installed. Under strict circumstances, we'd be able to popup a small window on your screen with important information. Of course, we'd never use this to spam our customers, its use would be restricted to critical messages.

Give the toolbar a try – we think you'll like it. And spread the word!
