Remove desktop assignment

In this blogpost I showed how to assign a certain vdi machine to a user. This has been made easier since in the vmware.hv.helper module. These days we can use this:

This week I got the logical question from Brandon Smith in the comments about removing the assignment. First I need to re-assign the desktop (I have been building a VMUG presentation about PowerCLI & Horizon view so things got messed up)

the result:

Now what need to be done is setting the base.user to $null. I am going to do this by connecting to the machine service and utilize the machinehelper to update the userdata.

We now need to connect to the machinehelper by doing a read on the machineservice. $ will give us the info we need to be able to do this.

From this it becomes clear that we will need the services service and the machineid we want to edit. First let’s put the machine id into a variable.

Now I will read the properties of this machineid and put this into the $machineinfohelper variable

Since I know the user property is under the base we will need to get the base first and then set the user. This done by doing getbasehelper() on the machineinfohelper and then do .setuser(user) on that but let’s see what’s under the getbasehelper first.

A lot of information but as said the one we need is setuser. To assign a desktop we will need to set this to a userorgroupid value (and that is what the vmware.hv.helper cmdlet does). To clear it we will need to set it to $null.

At this point no changes have been made yet! We will need to apply this update first.

And if we look at the horizon console the entitlement has been removed.

And the complete script:

As usual the script can be found on github.

Removing faulty Horizon desktops using PowerCLI

So last week there where a couple of posts on vmtn about people wanting to automatically removing or refreshing faulty Horizon desktops. With faulty I mean desktops in Agent Unreachable or in error state or whatever status are available. Since this was something i had been investigating anyway I decided to make a script for it that had separate menu’s for the status the desktop needs to be and to pick the desktop to be deleted. The latter part can be rebuild to do all those desktops at onceĀ  in case something breaks pretty badly during a recompose of the pool.

The largest part of the script is for creating the menu’s. Since the amount of returned desktops is variable and names differ it’s not possible to use a static menu. Instead I have used a menu structure created by Roman Gelman and that can be found inside this script on github. The part that gets things done i have listed below. The $spec array doesn’t need to be created but it is required in the API call to remove the desktop, Powershell assumes everything true by default when it’s empty but it just has to be called otherwise you will get a big fat red error. To remove multiple desktops at once machine_deletemachines needs to be used with an array filled with desktop id’s and $spec.

As always the complete script can be found at Github where it will also be updated. This is how it looks in the end:


After the comment below I decided to create the script to delete all desktops in a certain state. It’s a variation of the script above, just a bit shorter. Again it can be found on Github. Please be aware that due to a limitation in get-hvmachine both these scripts will only handle 1000 desktops at a time. It is safe to just repeat the script to do the rest.
