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.

Symptoms:

  • 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.

Horizon View Connection Protocols

The primary main connection protocols that customers use to connect to their virtual desktop infrastructures include PCoIP, BLAST, and to a lesser extent, RDP. Our front line tech support engineers have compiled this list of articles which cover the most common issues with PCoIP and BLAST:

Unable to access Administration and Licensing in vSphere Web Client

  • You are unable to access or see the Single Sign-On administration section
  • When attempting to access the System Configuration (located at: Administration > System Configuration) section, you are presented with:
    You do not have permissions to view this page. You must be a member of the SystemConfiguration.Administrators group in vCenter Single Sign-On to access System Configuration.
  • When attempting to access the Licensing administration (located at: Administration > Licensing > Licenses or Administration > Licensing > Reports) section, you are presented with:
    To view and manage licenses, you must have the Global.Licenses privilege on the vCenter Server system where this vSphere Web Client runs.
