Launching The VMware View Client With Google Chrome Using A URI Link

VMware View Client version 1.6 and above can be launched by using a URI . So for example if you click the following URI the VMware View Client can be launched automatically logging you into your View desktop. vmware-view://view.mycompany.com/Primary%20Desktop?action=start-session

More information on the VMware View URI Scheme can be found in my previous post: VMware View URI Scheme

One thing that I had noticed was that the application launching wasn't working when using Google Chrome both on my Mac and on Windows whereas Firefox, IE and Safari worked fine. Being able to launch the View Client from Google Chrome is something that I will be using more and more in the future, so I decided I would try and figure out how I can get this to work.

ALERT: vSphere 5.1 is not compatible with any versions of VMware View

Taken from: http://blogs.vmware.com/kb/2012/09/alert-vsphere-5-1-is-not-compatible-with-any-versions-vmware-view.html

VMware vSphere 5.1 is not currently supported with any versions of VMware View.

vSphere 5.1 is in the process of being certified against VMware View. We recommend that you do not upgrade vSphere above the supported versions listed in the VMware View 5.1 Release Notes.

For further updates and more information on this alert, refer to KB article:
vSphere 5.1 is not compatible with any versions VMware View (2035268).

VMware View: Recompose fails to recompose the whole pool

Problem
I've seen this issue a lot with customers. The customers wants to Recompose an entire pool to a new snapshot, so they set off a "Recompose at LogOff" task to make the recompose happen as users log-off of their desktops. However, quite often none of the desktops in the pool get recomposed. Every time I've seen this issue, the customers have their desktop pools to "Refresh On Logoff"

Cause
The Refresh on logoff task supersedes a scheduled Recompose task. When you log off, the recompose task for that virtual machine is discarded.

Fix
Change the pool "Refresh On Logoff" setting to Never before scheduling a "Recompose At Logoff" task. (Remember to re-enable "Refresh On Logoff" after the pools has been successfully recomposed.)

VMware View Persona Management

Persona Management, previously called RTO Virtual Profiles. A sleeping giant in my eyes. It's soo simple to install and configure but can offer you riches beyond your wildest dreams. OK, maybe a little over the top, but it is a really cool product and very underrated.

With VMware ViewTM 5, VMware introduces View Persona ManagementTM. View Persona Management preserves user profiles and dynamically synchronizes them with a remote profile repository. View Persona Management does not require the configuration of Windows roaming profiles, and you can bypass Windows Active Directory in the management of View user profiles. If you already use roaming profiles, Persona Management enhances their functionality.

Persona Management downloads only the files that Windows requires at login, such as user registry files. When the user or application opens other files from the desktop profile folder, these files are copied from the stored user persona to the View desktop. This algorithm provides performance beyond that achieved with Windows roaming profiles. 

As it's still pretty new, detailed information on the InterWeb is limited so I thought I'd put together a post displaying how Persona Management functions. Installation/Configuration information can be found in the View 5.0 Administration Guide or in the VMware View Persona Management Deployment Guide.

Persona Management Logic Flow

Persona Management is based around Logic Flows which runs through a set of checks. Each step has to be completed before the next to ensure the process completes successfully. I will try and explain at a high-level what happens in each of the following Logic Flows:

  • When a user logs in
  • Whilst the user is logged in
  • When a user logs out

PCoIP Log Viewer 2.0

This is a tool I've been using almost daily in my current project and for the past few months. Now It's finally been released to the public! The tool has been created by Chuck Hirtsius – one of the EUC Specialist's within VMware. 

The release you see here today is the first release of the tool that provides log file visualization as well as real-time monitoring of the PCoIP WMI counters.

PCoIP Log ViewerThe PCoIP Log Viewer and the Log Parser can be downloaded from the following website: http://mindfluxinc.net/?p=195 Instructions on how to parse the logs ready for the Viewer should also be available on that link. 

Now you have the tool, I guess you'd like to know how to make use of it? As I mentioned, I've been using it extensively to help me troubleshoot poor PCoIP performance. To help myself remember and to enable others to understand all of the PCoIP counters better I have put together a PCoIP Troubleshooting page. This should have all of the information you need to make the most out of this brilliant free tool.

VDI Paging Files – Big? Small? Or None At All?

VDI - Paging FilesFor the past few months I have been spending a lot of time looking at the performance of Large VDI environments, where the problems lay and where performance can be improved.

When designing VDI environments, a couple of things that you should consider are the .vswp file and the GuestOS paging file. In this article I am going to focus on the Paging file and hopefully in the not so distant future I will write a post about the .vswp file in a VDI environment.

What is point of the paging file (also known as the pagefile.sys)?

RAM is a limited resource. Virtual memory was introduced to help remove that limit.

Most modern operating system now use Virtual Memory. Virtual memory is a memory management technique. Applications running on a GuestOS reference memory using virtual memory addresses which are then automatically translated into RAM addresses by the hardware. These virtual memory address spaces are divided in pages or block, usually of 4KB. 

If RAM resource is exhusted, the operating system will move 4KB pages of the virtual memory onto the computers hard disk to free up the physical memory (RAM) for other processes. In Windows operating systems, these pages are stored in the pagefile.sys. 

A good way to think of this is;

Imagine a restaurant that has just open for the evening. When customers (Processes) arrive they get allocated a table (RAM) to sit and eat at. As the night goes on the restaurant get busier and free tables (RAM) begin to run out for the new customers (Processes) coming through the door. To free up spare tables (RAM) the waiter asks customers (Processes) who have finished eating if they wouldn't mind moving to the bar (Virtual Memory) where they can continue drink.

Without the paging file, if the physical memory becomes full, applications including the operating system will have to waiting until physical memory becomes available before it can be stored in RAM ready for the CPU to process. As you can imagine this causes massive performance problems.

In summary, you NEED to have a paging file.

VMware View 5.0 Maximum Composer Pool Size

There has been a lot of talk around this but it seems that not a lot of people are aware, so I just wanted to clarify the point. As mentioned both at myvirtual.net and in the VMware View 5.0 Architecture Planning Guide

The maximum VMware View 5.0 composer pool size is now 1000 desktops.

This will make some customers very happy I am sure.

My Last Year = Desktop, Desktop, Desktop

desktop madness

I'm pretty sure all of you know I work for VMware's PSO. But did you know that for about the past year I've been specializing in VDI, specifically View? Probably not. Not a lot of people know that! I didn't know that people didn't know that, until recently at a few vBeers events I've been telling people what I've been getting up to and everyone was quite surprised. So I thought I'd share some of my experiences with you.

The two main types of engagements I've been working on are View Plan and Design and VDI Troubleshooting/Healthchecks. All of the engagements mentioned are 1000+ seat environments, all large scale and some global.
