McAfee Exclusion for VMware App Volumes 2.x – 100% CPU Issues

27 Nov

In your Virtual Desktop Infrastructure with the following configurations:

If you start noticing 100 % – CPU Usage for prolonged period of time and the Horizon Session getting disconnected from time to time after launch then you might need to include the following exclusion within your Writable Volumes (UIA+Profile) snapvol.cfg file:

exclude_process_path=\Program Files\Common Files\McAfee\SystemCore

My colleague Daniel Bakshi has written an extensive blogpost on how to modify the snapvol.cfg for individual or group of end-users please reference it to make the necessary changes – Using the VMware App Volumes snapvol.cfg File to Customize Writable Volumes

I hope you will find these exclusion useful and will help you resolve a similar issue a lot quicker. A big thanks to Art Rothstein in helping to troubleshoot and resolve the issue.

Horizon 7.2 – RDS Farm with View Composer fails on “Customizing”

21 Jul

While creating a RDSH Farm in Horizon 7.2 using View Composer – Linked Clones and Custom Specification Manager the creation would fail on “Customization” within the View Administrator console. Upon investigation within the vCenter the Windows Servers 2012 R2 RDS Session host VM’s where not getting a valid IP and receiving the169.x.x.x APIPA addresses.

After researching quite a bit the most common solution to the problem was:

  • Un-install and re-install vmwaretools
  • Un-install and re-install Horizon Agent 7.2 on RDS Master Image

After performing the above two steps the issue completely changed from getting 169.x.x.x APIPA address to a proper DHCP server routable address. However, we are getting a different error this time:

Windows could not finish configuring the system after a generalized sysprep”.

Final Solution

Within the master image we were using the MacAfee VSE Agent Patch 7 as the antivirus protection. This particular version was causing the issue with the sysprep to fail during customization.

After following the below MacAfee KB and installing VSE Patch 9 the error was resolved and customizing of the RDS VM as per the Custom Specification Manager was successful.

Windows could not finish configuring the system (Sysprep fails when VirusScan Enterprise Patch 7/8 is included in a Windows installation image)

I hope this solution will save time to get the Horizon 7.2 RDSH Farm created quickly.
