VMware released VMware View 5.1.1 yesterday (8/16/2012). The update addresses a few different issues , and applies only to VMware View Connection Servers, not View Security Servers, View Transfer Servers, View Composer, or View Clients.
The first issue resolved in the VMware View 5.1.1 update is a scalability fix for View deployments over 10,000 desktops managed by one group of View Connection Servers. If you are following standard View reference architectures as pictured below, your View Pod should extend beyond 10,000 desktop. If you did scale to near or beyond 10,000 managed entities (desktops, pools, and users/groups combined), View Administrator might intermittently have problems displaying objects. This fix resolves the display issues, but you should still follow good architecture design practices when scaling out your View environment.
The second set of issues resolved by this update pertain to View Persona Management. Persona Management, as well as VMware ThinApp and Horizon Application Manager, are key to achieving a stateless desktop computing environment. The closer to stateless you move, the lower your end user computing operating and capital costs will be.
View 5.1.1 fixes problems with Persona Management that could lead to data loss for your user’s Persona profile data. Persona generally works very well, but if a user were to commit a large file to their View profile and log off their desktop before the file could replicate to the network View profile repository, the file could become corrupt or lost. This problem would be seen most in environments where the ‘Delete or Refresh Desktop at Logoff’ Pool policy was set to ‘Refresh Immediately’ or ’Delete immediately’ options. This would cause View to revert the VM to the pool clean snapshot state or delete and recreate the VM before the profile data had synchronized. View 5.1.1 now waits for the profile replication to complete before allowing Composer to refresh or delete the used desktop.
View 5.1.1 also fixes an issue where a user logged off of one View Desktop and immediately logged into another. Prior to the update this set of actions could result in inconsistent Persona profile data, including loss of data from the first, logged-off desktop.
The release notes for View 5.1.1 detail the fixes included, and also include a slew of Known Issues for View (there are a bunch!). Give it a read and start planning your update.
I just saw that the Amazon Kindle DX 9.7″ eReader (Kindle DX, Free 3G, 9.7″ E Ink Display, 3G Works Globally) got a pretty deep price cut, down to $269. The eReader doesn’t have the full-blown color screen or Android experience of the Kindle Fire, but I’ve found that it is awesome for reading technical documentation. The large, no glare, black & white screen is distraction free, helping me to focus on the (let’s be honest, sometimes boring) technical documentation and publications I’m reading. I carry my DX in my backpack, loaded with technical books, formal documentation, and the occasional bit of pleasure reading. The battery life is great and 3G access on the DX guarantees that I have my documents ready to go when I’m on a flight, subway, or at a client site. The large screen easily displays diagrams, charts, and graphs without scrolling or funky resizing like you see on a smaller screen. I also like being able to highlight and notate sections of text for later reference – the full keyboard on the DX model makes this easy.
Here’s a pic of my Kindle DX (on top of my VMworld 2011 backpack) with the VMware View 5.1 Administration document open with a big chart of View GPO policies displayed. Not too shabby!
The price drop probably indicates some newer Kindle and or Kindle Fire models are soon to be released, but for the price and abuse the thing can take in the old backpack I don’t mind having a slightly older piece of technology for this use case.
VMware makes much of their documentation available in .mobi and .epub format, as well as PDF. Head over to https://www.vmware.com/support/pubs/ and grab the .mobi file. Connect your Kindle DX to your computer and drop & drag the files to the Kindle’s storage. If you are getting technical docs from another vendor in .epub format, grab a free copy of Calibre (available for PC, Mac, or Linux) and convert the files from .epub to .mobi. You can also load PDF documents in the same way, although formatting can sometimes get a bit funny. If formatting is off, email the PDF to your @kindle.com address and Amazon will convert it for you and deliver it over 3G or WiFi to your Kindle within minutes.

Since joining Clearpath Solutions Group I have had many opportunities to present at company events, as well as at VMware User Group events and VMware Knowledge Series events. I’m pretty serious about my introverted nature (I highly recommend the book Quiet: The Power of Introverts in a World That Can’t Stop Talking for anyone figuring out how navigate your own introversion in your professional or personal lives). I’ve been very pleasantly surprised at my comfort and enjoyment in presenting in front of large groups, and interacting with the audience. I’ve found that when I share my passion for VMware and how it can transform the day to day lives of technology professionals (or even transform their careers, as VMware has done for me), I come home energized and excited to push my knowledge of virtualization and cloud technology further.
I had the honor of speaking at two VMware Summer Knowledge Series events last week, in Atlanta, GA and Hanover, MD. The topic I was asked to speak on was ‘How to Get Started Enabling End User Computing Platform for the Post PC Era’. I wanted to offer something beyond the standard sales pitch, and paint a picture of how adopting the VMware End User Computing (EUC) stack can help energize IT, excite end users, and provide a foundation for this radical shift towards ‘cloud’ and the software-defined datacenter. The presentation was well-received, so I thought I would publish the transcript and slides here. I welcome your feedback, and hope that it helps illuminate a Clear Path on your IT journey.
Hello, and thanks for coming out to today’s VMware Summer Knowledge Series, sponsored by Clearpath. My name is Josh Townsend. I am Clearpath’s Virtualization Practice Manager, where I oversee all things VMware. My role can be summarized like this – I’m responsible for delivering technical excellence in all things virtual for our customers, from initial planning phases, through sizing and scoping, implementation and on-going support. I’ve been working with VMware solutions for 10 years. I carry a pile of technical certifications from Microsoft, including MCITP: Enterprise Administrator. I am a VMware Certified Professional – VCP3, VCP4, and VCP5 – and have been recognized by VMware as a vExpert in 2010, 2011, and 2012. I lead the Washington, DC VMware User Group and am an active blogger on Clearpath’s blog (https://blog.clearpathsg.com) as well as my own site, https://VMtoday.com.
Today’s Knowledge Series event is focusing on VMware’s End User Computing technologies, including VMware View virtual desktop infrastructure and Horizon Application Manager products. As you’ve seen in today’s technical demonstrations, these products and the ecosystem that surrounds them provide a mature, stable, and robust set of tools to allow IT to begin managing the technologies that our end-users interact with most to execute on their mission for the business – desktops, user-generated data, and applications – in a an efficient, cloud-like model – just like how VMware vSphere virtual infrastructure has enabled us to drive efficiency and operate in an IT-as-a-Service fashion for our core infrastructures.
Now everybody is talking cloud these days – at Clearpath we say “We Speak Cloud” – but I want to limit the use of the word in the rest of my presentation, step back from the technical marketecture, and paint a picture of what adoption of VMware’s End User Computing stack could look like for you. It is my hope that this presentation will illuminate a Clear Path for you as you leverage these VMware End User Computing solutions to:
provide technical excellence in your day-to-day operations
break down barriers between IT and users,
and free you to deliver strategic business value through aligning IT with business objectives and user demand.
Prior to joining Clearpath, I worked as IT Director for a Department of Defense contractor, managing both internal IT systems, as well as systems located in the Pentagon. While my mission paled in relation to that of the war-fighters my team supported, there were days that I came home feeling like I had done battle – fighting security skirmishes, wrestling with legacy technology that would not bend to my orders, and yes, even doing battle against my end users. The end-user conflict was the most frustrating and exhausting – after all, we were on the same side, trying to do our own parts to accomplish the greater mission. But the security requirements, supportability, and quite frankly, some of the legacy technology we had to deal with, left my team and me at odds with end users who were demanding more choices for connectivity, greater mobility, and more flexibility in when, where and how they worked.
As I considered ways to break down the barriers that divided my group from the end users, I remembered a line from one of my favorite movies: We Were Soldiers, based on the fantastic book We Were Soldiers Once…and Young: Ia Drang – The Battle That Changed the War in Vietnam that provides an account of one of the first large engagements in the Vietnam war – the Battle of Ia Drang Valley. The book and movie give background on the start of the Vietnam war and the development and testing of a new war fighting strategy – Air Cavalry, empowered by new technology – helicopters, to meet the challenges of a new type of enemy; an enemy that did not follow traditional rules of engagement, were highly mobile, and preferred to work, if you will, on their own turf. Sounds familiar….
In one of the more touching scenes in the movie, a young Lt. who just had his first child finds Lt. Col. Hal Moore, played by Mel Gibson, in the base chapel just before their unit was to deploy to Vietnam. The Lt. asked Col. Moore “What do you think about being a soldier and a father?” Col. Moore responded, “I hope that being good at the one makes me better at the other.”
As a young father myself, I wondered what if, instead of doing battle, I parented my user base. What would that look like? I’ve got two young sons that run circles around me. Early on in my adventures in parenting, my mother gave me some sage advice.
First, be Firm, Fair, and Consistent. Second, as a parent you so often have to say “No” – find ways to say “Yes” as often as possible.
I considered these two rules and how I might apply them to my job. Security, regulatory, and operational requirements definitely required my team and me to be firm, fair and consistent, and often led to me having to say “No” to my users. It was the second rule that I had been neglecting, and in discussing this with many of my IT Manager friends I found that they too (and I suspect you also) do not always look for ways to say “yes”.
As IT Administrators, we’re comfortable in Layers 1-7. But, I’ve been talking Layers 8, 9 and 10 issues so far. Layers 8 through 10 are normal parts of the human and IT experience. The problem is, legacy technologies in layers 1-7 do not lend themselves well to the new cloud era where 8, 9, and 10 gain importance.
Trying to force legacy technology on top of layers 8-10 is like forcing the old square peg through the round hole, and often leads to the blame game. When you stop fighting layers 8 – 10, and instead manage or <gasp> even embrace them, the right technology can shine.
That said, let’s look at how VMware’s end user computing technology can help you meet the challenges of the new cloud era – specifically:
New (Cloud) Delivery Methods
New Devices, leading to a more mobile, independent workforce.
New Applications
New Real-time, collaborative Work styles
In the past several years, we have seen a paradigm shift, driven by these New methods, devices, apps, and work styles. We have now entered the Post-PC world, where the focus shifts from IT servicing devices, to IT Delivering Service in the form of Data and Apps, to users, on any device, anytime, anywhere.
Let’s look at how we tackle the challenge of this Post-PC World.
The first step in adopting this new post-PC world mentality and starting to break down the barriers between IT and users is to take charge of the applications in your environment, and begin to offer Apps as a Service. VMware offers several solutions that enable IT to reign in legacy applications, provision new SaaS applications, and allow users to self-provision the apps that they need, when they need them.
The first solution is VMware ThinApp. ThinApp is an application virtualization solution that allows IT administrators to repackage legacy applications into simple, portable, self-contained apps. Once apps are thin, we can eliminate compatibility issues, Windows version dependencies, application conflicts, IE versions, etc.
Packaging ThinApps is quick and easy, and now more automated with the release of VMware’s latest ‘Fling’ – ThinApp Factory.
Once your applications are thin, deploying and updating them is as simple as dropping a file in a share. When users launch an application, they are guaranteed to use the latest IT approved and provided version of that app, reducing support calls, eliminating security risks, and eliminating complicated application patching mechanisms.
ThinApps can be injected directly into VMware View virtual desktops for an even greater degree of simplified management.
Now, take the solution further – rather than pushing ThinApps to users and hoping you’ve given them all that they need, or risk over deployment driving up licensing costs – think self-provisioning. VMware Horizon Application Manager is an enterprise app store that presents both ThinApps and SaaS apps to users so they can self-provision. SaaS apps managed by Horizon gain Single Sign On capabilities, so users have a seamless experience in authenticating to apps, and security teams have fewer passwords floating around to worry about.
We’ve talked about how mobility changes everything. With the decline of Blackberry, and increase in user-provided devices, the tools to manage mobile devices have been limited, and often upset users when IT ‘takes over’ their personal devices. With VMware Mobile Management Platform and VMware Switch, IT can allow users to bring their own devices, preserving user choice, portability and security.
With VMware Switch, mobile devices take on a split personality – one for personal, one for work. IT manages the work profile – apps, data, and policies – and can destroy the virtual work smart phone in the event of loss or attrition. Users keep their personal device with the personality they choose.
Now that we’re in control of apps, let’s look at the desktop. Before we talk about boring old Windows, let’s think again about the concept of the post-PC world. If Windows is Windows for Windows sake, then why are we using it? Because it is a portal for interaction with legacy apps, and a file management system for our users.
We’ve virtualized legacy apps with ThinApp, and now, with VMware View Persona Management, we can abstract user profiles and the data they contain from the desktop OS. Once we do that, IT controls where data is, when it is backed up, where it is replicated to – all while allowing users to access their data, their profile, their persona whenever they log in.
With Apps and Data abstracted from the desktop, we can start to think about the stateless desktop. Windows for Windows sake until we don’t need it any more. Then, we’re left delivering the services – Apps and Data – that our users really want.
Let’s look now at a few of the driving factors for desktop virtualization.
Desktop virtualization is the beanstalk in the cloud-provided end user computing environment. Rooted in today, climbing to the cloud of tomorrow.
Desktop virtualization acts as a decoupling agent between the OS and apps/data that users really want.
Desktop virtualization provides a reset button for IT, allowing us to reimagine, reclaim, and redeploy IT assets (people, equipment & budget).
Desktop virtualization changes the economics of end-user computing from CapEx to OpEx, preparing way for consumption-based cloud models.
Now, some more practical benefits of Virtual Desktops – benefits specific to the IT administrator’s day-to-day life – the things that keep us awake at night:
Security
User Data Control
Operational Efficiency
Bottom line: We can control more than we could with physical desktops, roaming laptops, and unmanaged mobile devices. We can be the Colonel in charge, we can be the parent who is firm, fair and consistent. But with View, we can allow users to choose how, when, and where they access these IT controlled resources.
But wait, there’s more! With increased operational efficiency, we cut down on sneakernet, deliver faster and higher quality of service to our users, all while pleasing the corner office!
Once we achieve secure, stateless desktops on VMware View, with IT controlled applications and user data being delivered where ever users need it, we are free to begin saying “yes” to our users.
User Freedom is now the norm.
Bring Your Own Device (BYOD) can be a reality.
Now that we have control of our apps, with ThinApp and Horizon, are enjoying the benefits of stateless desktops with View, and sleeping better knowing that we are in control of mobile devices – all while balancing our need to be firm, fair, and consistent; but saying yes to user choice and new ways of working, let’s look at how this all fits into your VMware environment.
First, build a flexible, scalable and efficient infrastructure based on VMware vSphere and automated with vCloud director. Then, ThinApp and Horizon and ultimately look at modernizing those legacy apps – VMware offers SpringSource and vFabric application fabrics and data fabrics for this. Finally, layer on secure desktop and mobile devices that empower your mobile workforce.
It boils down to this: VMware offers Multiple Platforms with one Common Goal: to deliver a broad range of technology and services to transform how we build, deliver and consume applications in the Post-PC, cloud era. With these platforms in place and working together, we can drive IT Agility to increase business value through:
Reduced Complexity
Dramatically Lowered Costs.
Enable Flexible, Agile IT Service Delivery
With an understanding of how these technologies fit together and promise radical change for IT and the users we support, let’s look at how Clearpath can help propel your adoption forward.
Clearpath offers a portfolio of Products and Services focused on the virtual datacenter, with key competencies that include desktop and application virtualization with a highly qualified staff.
Clearpath’s Cloud Hosting can help you get started with VMware View by hosting a custom pilot environment, or we can continue to host your production VMware View environment in our cloud, either as a dedicated environment for you, or in a Desktop as a Service (DaaS) offering, depending on your needs.
By inviting Clearpath to be a part of your IT lifecycle, we can help you bring these new technologies to bare as you evaluate, design, deploy and operate your own private cloud platforms.
First (Repeat after me…), start the journey towards the cloud.
Now, how about something a little less fluffy – take these very practical steps towards implementing your own post-PC environment.
Review your real user needs; Identify technology options
Repackage applications; Virtualize all you can, upgrade/replace others; Establish “rules” for new applications
Rationalize desktop image builds; Begin pilot of virtual desktops
Start virtual desktop deployment; Synchronize with OS migration
Identify “local” requirements; Extend virtual desktop deployment through use of desktop personas
Device independence for all virtual desktop users
Finally, reach out to Clearpath for help in designing and implementing your modern end user computing environment based on VMware vSphere virtual infrastructure, VMware View & Horizon, Cisco networks and servers, and EMC storage.
In the end, as IT professionals, we have play the role of both Colonels and fathers in our support and enabling of our end users. Being good at one will make us better at the other. But by leveraging the VMware technologies we’ve seen today, we’ll spend much less time fighting with our end users. Instead, we’ll find that we can deliver the best of both worlds – security, stability and supportability on one hand, and flexibility, mobility, and freedom on the other.
I hope my presentation provided inspiration and clarity for you. I look forward to my team and I at Clearpath engaging with you and your team to design and deliver VMware’s end user computing solutions to enable and inspire your IT group’s delivery of agile services to your business – without fighting with your users, but empowering them.
I’ve had several customers ask me for help with the VMware View environment recently, as their users were complaining about performance issues when dragging a window between monitors in a multi-monitor VMware View setup. Performance was otherwise acceptable on the View desktops. I recommended several troubleshooting and remediation steps to get windows to stop slowing down when dragging between monitors or “catching” on the border between the two screens, including:
Review the “Multimonitor PCoIP sessions are not displayed as expected KB article” (1030566) from VMware.
These steps either yielded no results or were not easy to do without some planning and change control.
Then I stumbled on VMware KB article 2010359, “Poor performance when moving windows between multiple displays in View 5.x session.” The article was just updated yesterday (7/25/2012) to include View 5.1 as an affected product.
From the KB article:
This issue occurs due to the way View handles the transition of a window from one display to another. It relies on the MKS poll rate which is optimized for server configurations to reduce CPU cycles.
This issue is limited to this configuration:
Windows 7 View virtual machines (both 32bit and 64bit)
Virtual machine hardware version 7 or 8
View Agent 5.0
Client desktop utilizing multiple displays
For those who don’t know, MKS is:
Mouse Keyboard Screen (MKS) process – A process that is responsible for rendering the guest video and handling guest operating system user input.
See VMware KB 1019471 for more on MKS, VMM, and VMX processes, as well as how to interpret error for all of these services.
The fix is to enter an advanced configuration parameter on the affected virtual machine as follows:
Power off the virtual machine using the vSphere Client.
Right-click the virtual machine and click Edit Settings.
Select the Options tab and under Advanced.
Click General.
Click Configuration Parameters and click Add Row
In the Name field enter mks.poll.headlessRates and in the Value field enter 1000 100 2.
Click OK.
Power on the virtual machine.
When the virtual machine is powered on, it will read the new configuration.
Pretty easy, no? Not so fast…. The fix requires downtime, for all your View desktops. And, if you are using VMware View Linked Clones, the change you make to any of the clones will be lost when the VM’s are refreshed at log off, rebalanced, or recomposed. To get the fix to stick, you need to update the template on which your pool is based on then recompose the pool. If a recompose is not in your immediate future, you may have to tell your users to wait it out.
The script should be applied with all target VM’s powered off. That said, I ran it in the Clearpath lab against a running pool of View Linked Clones and had the .vmx file updated. The VMware KB clearly states that “When the virtual machine is powered on, it will read the new configuration.” From my testing, the setting did not seem to take place on the running VM’s until I rebooted them – but your mileage may vary.
Also note (per the VMware KB article 2010359) , there is a risk in making this change to your View desktops – CPU utilization on idle VM’s can increase. Less idle time means higher CPU usage on your ESXi hosts/cluster and increased CPU Ready in your environment. I did not see an increase in my environment, but the lab is small. Test, test, backup, test some more, and backup again before making the change or running my script.
The script is below. Update the vCenter server variable and the name of the vCenter folder (not the View Administrator folder) that contains your View desktops.
