Disable your VMware View users rights to remove VMXNET 3 Network Adapter

One thing that can really be a pain for your Horizon View users and support people is users that remove the VMXNET 3 network adapter. When a user does this they will be disconnected as the VM they they where using will not have a network card anymore. This is a configuration issue on your View Pool templates that can be fixed with not a lot of work.

Keep in mind this fix is for View Pools that meet the following critria

  • Must be a VM using the VMXNET 3 network adapter.
  • Using linked Clones or Instant Clones for your  Horizon View Pools. 
    • If you are using Full Clone desktop pools you will need to update the VM template as listed below but skip the snapshot steps. You will also need to update each full Clone VM that has already been created.

For those of us that still love the old school C# vSphere Client follow the following steps to complete the fix.

  1. Start the vSphere Client and connect to your vCenter Server. 

  2. On your parent VM used for your Horizon View Pools make sure it is powered off if not already.

  3. Next Right Click the VM and client the edit settings button.

  4. Select the Options tab in the settings window. 

  5. Click on General ===> Configuration Parameters ===> Add Row

  6. Name the new row devices.hotplug and set the value to False.

  7. Now create a new snapshot for your parent VM

  8. To complete this process do a recompose for linked clones or a image push for instant clones.

For the new web client follow the following steps to complete the fix.

  1. Using your web browser connect to the vSphere Web Client

  2. On your parent VM used for your Horizon View Pools make sure it is powered off if not already.

  3. On the parent VM select Edit Settings.

  4. Select VM Options tab.

  5. Select Advanced ===> Edit Configuration ===> Add Row.

  6. Name the new row devices.hotplug and set the value to False.

  7. Now Create a new snapshot for your parent VM

  8. To complete this process do a recompose for linked clones or a image push for instant clones.
