New KBs for new desktop products

As you have probably heard by now, VMware yesterday released shiny new versions for it’s desktop virtualization products: VMware Fusion 8 and VMware Fusion 8 Pro, and VMware Workstation 12 Pro & VMware Workstation 12 Player. To go along with these new versions, the Knowledge Experience Team has created some new Knowledgebase articles and/or updated existing articles. Here is a list of what you need to know.

Disk is already managed by View

Horizon ViewToday we will highlight one of our KB articles that is getting some traction with our Horizon View customers. The  issue can occur if the ADAM database contains an invalid entry for a persistent disk.


  • Attempting to import the disk from vCenter Server fails with the error:
This disk is already managed by View
  • Cannot detach a Persistent User Data Disk in View Manager.
  • Cannot import a Persistent Disk from vCenter Server for a virtual machine that was deleted in View Administrator.
  • The Persistent disk is visible when the option to show incompatible files is selected.

If you are encountering any of these symptoms in your environment, please refer to KB article: Cannot detach a Persistent Disk in View Manager 4.5 and later (2007076). This article has a 5 star customer rating.

Note: This KB contains two Warnings. Be sure you completely understand the article, and as always check that your backups are working and are valid.

Database issues when upgrading vSphere

For today’s post, we’d like to focus on issues surrounding DB validation during upgrade. Many of you are running into one of the issues when moving to vSphere 6.0

Does anything here look familiar?

Invalid Linked Clones – revisited

Back in July we had a post about using the ViewDbChk command to remove invalid linked clone entries, which applied to Horizon View 5.3 and later. Apparently a similar situation can arise in earlier versions of the product as well, but the steps to fix it are different.

For users of View 5.2 or earlier, we have created KB article: Manually deleting linked clones or stale virtual desktop entries from the View Composer database in VMware View Manager and VMware Horizon View.

Symptoms include:

  • You cannot provision or recompose a linked clone desktop pool
  • You see the error:
Desktop Composer Fault: Virtual Machine with Input Specification already exists
  • Provisioning a linked clone desktop pool fails with the error:
Virtual machine with Input Specification already exists
  • The Connection Server shows that linked clone virtual machines are stuck in a deleting state
  • You cannot delete a pool from the View Administrator page
  • You are unable to delete linked clone virtual machines
  • When viewing a pools Inventory tab, the status of one or more virtual machines may be shown as missing

So remember, if you have 6.1 or later, you want to use KB article: Removing invalid linked clone entries automatically using the ViewDBChk tool in VMware Horizon View 5.3 and later versions (2118050)

If you have 5.2 or earlier, use: Manually deleting linked clones or stale virtual desktop entries from the View Composer database in VMware View Manager and VMware Horizon View (2015112)

Web Client issues in vSphere 6

Today we’d like to talk about some common issues that have been seen when customers were upgrading to the latest version of our vSphere Web Client.

KB 2121717 Troubleshoots login issues that customers may see in the vSphere environment using the Use Windows Session Credentials check box.


How to confirm ESX and ESXi host hardware compatibility

We’ve just put the finishing touches on a new video which discusses how to confirm ESX and ESXi host hardware compatibility using the VMware Hardware Compatibility Guides, which are available here.

You can use the VMware Hardware Compatibility Guides to confirm whether or not your particular server, system, HBA, network card, or other peripheral devices are certified and compatible for use with specific vSphere ESX and ESXi versions.

Additional information is available at Confirming ESX/ESXi host hardware (System, Storage, and I/O) compatibility (1003916).
