VMware Horizon and RDSH Applications

One of the big new features of View 6 is the ability to use Terminal Server… err… I mean Remote Desktop Session Host RemoteApp applications.  As you’ve probably seen, the application presentation is pretty slick, behaving very much like natively installed applications even though they’re running on a server in the datacenter.  This allows for neat little tricks like launching Windows applications on an Android device.  In the demonstrations, this feature is just about always paired with Workspace 2.0, showing those RDSH applications in the Workspace 2.0 launchpad.

It isn’t really clear from the marketing that’s going on, but RDSH application support is a View 6 feature, not a Workspace 2 feature.  When you want to present a RemoteApp, you must register the RDSH server in View and create an Application Pool.  From there, you can optionally tie it into Workspace or you can just launch it directly from the View Client – your choice.  So, how do you install your RDSH and present your first RemoteApp?

Well, you start by following VMware’s guide.  If you’re working with a 2008 r2 server, this guide is probably all that you need.  It’s a pretty straightforward process… but if you’re working with 2012 or 2012 r2, there’s a few extra steps that you’re going to need to go through.  In 2012, Microsoft assumes that you’re going to be setting up their whole RDSH infrastructure, which includes its own Connection Server/Gateway infrastructure that we just don’t need.  We’ve already got View serving that role in the environment.  So, here’s a KB article that describes installing just the components that you want for View + RDSH.

What’s more, the 4th section of the VMware instructions tell you to go to Administrative Tools > Remote Desktop Services and launch Remote Desktop Session Host Configuration.  On your 2012 server, you’re going to have a real hard time finding that tool… as it doesn’t exist.  The configuration that we need to make is to restrict users to a single session on the Terminal Server… err… Remote Desktop Session Host, which is required for the View integration.  Fortunately, that is the default setting on a 2012 server, so you can safely skip that step.  If you’d like to verify that setting, the easiest way is to open up regedit and check out the following key:

HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\fSingleSessionPerUser

Verify that it is set to 1.


Once those steps are done, you can basically just follow the VMware instructions to complete the process.  Install the View Agent on the 2012 server, which will prompt you for information about your View Connection Servers.  Completing that process will register the server as a RDS Host, which will allow you to create a Farm and then an Application Pool.  Have fun!

PowerShell Sorting by Multiple Columns

PowerShell's Sort-Object cmdlet is super useful, especially when preparing output for human consumption.  A few people have found my blog while looking for more information about its use, specifically while looking for how to sort by multiple columns (well, properties, technically).  I've never done so (much less written about it), so I hope those folks found answers elsewhere.  But, it got me curious... and it turns out that it's really easy. The Technet article on Sort-Object has the answer directly spelled out: just use commas to create a list of properties to sort by (in order to precedence).  Let's look at some examples!  First, prepare a variable with some good sortable data: $myData = get-eventlog System -newest 25 And then we can get to sorting!  Say you want to sort primarily by EntryType (Warning, Information, Error) and then by Source.  Easy-peasy: $myData | sort EntryType,Source How about if you want it to be in descending order?  Yeah, there&

Clone a Standard vSwitch from one ESXi Host to Another

One of my customers is standardizing the configurations on their HP C7000 enclosures (they've been set up at various sites by various administrators with varying involvement from the architecture team).  As such, we need to stand up some temporary resources so that we can take down the main enclosure for reconfiguration.  That's fine, we can easily ship a smaller enclosure to each site for temporary compute resources.  Some of the sites are using Standard vSwitches, so we need to be able to quickly copy the networking configuration over from their existing blades to these new, slightly different blades.  As I see it, we had 2 good options: 1) Capture a Host Profile with the desired vSwitch configuration.  Delete every other component of the Host Profile so that only the networking section is applied; design the new ESXi hosts so that the vSwitches'll work with the old vmnic-to-vswitch configurations. 2) Write a script to clone the vSwitch from ones ESXi host to another.

Deleting Orphaned (AKA Zombie) VMDK Files

A problem that most Virtualization Administrators need to deal with is Orphaned VMDK files (or Zombie VMDK files, as some people call them).  These are Virtual Machine hard drive files that are just hanging out, taking up storage, but are attached to no VMs.  How can this happen?  Well, the most common way is when an administrator needs to delete a VMDK but isn't quite ready to commit... so, after pressing "remove", they select "remove from virtual machine" rather than "remove and delete files".  The intent is always good: "I want to be able to restore this if it turns out to be necessary... so I'll just come back and delete it next week if nothing breaks!"  But, of course, next week something else happens and the file doesn't get deleted.  After a little while, it turns into "which files did I rename, again?" and nothing seems to happen. So, how do you deal with these orphaned files?  Well, a few years ago I found a scrip
