When integrating XenDesktop with vSphere or vCenter respectively, you might encounter the following error message:

„Cannot connect to the vCenter server due to a certificate error. Make sure that the appropriate certificates are installed on the vCenter server, and install the appropriate certificates on the same machine that contains all instances of the host service.“

Solution:

1. Connect to your vCenter server and browse to „C:\ProgramData\VMware\VMware VirtualCenter\SSL“

2. Copy the cacert.pem file to your XenDesktop Broker (to the C:\Temp directory for example)

3. Open a Microsoft Management Console (by running the mmc.exe command) as an Administrator

4. Add the Certificates Snap-In and select to manage certificates for the local computer account.

5. Browse to „Trusted Root Certification Authorities“ and select Import

6. Import the cacert.pem file. (You need to select „All Files“ from the dropdown menu in the lower right hand corner, to be able to see it)

7. Now you should be able to see the vCenter certificate in the list of trusted certificates and XenDesktop should connect to vCenter without any error message.

Result:

At long last, Microsoft publicly recognizes a shift in IT computing trends as indicated in their recent announcements around desktop virtualization and their changes to VECD licensing to support the adoption of virtual desktop environments.  By loosening up the restrictive desktop virtualization license policy (VECD), Microsoft has finally bowed to intensive customer pressure.  This validates the acceleration in demand in the desktop virtualization industry that VMware helped start and continues to lead.  Microsoft’s move here is extremely positive for the industry.

This decrease in Microsoft licensing costs will decrease the overall CAPEX cost, thus building a better business case for VMware View.  Starting July 1, 2010, VECD is going away for customers with Software Assurance (SA) and for those without SA, Virtual Desktop Access (VDA) is available for purchase to allow for VDI environments.  Here are the details:

• PCs covered under SA will no longer need a separate VECD license, instead this usage right will be included in SA thus eliminating the separate $23 per device fee.
• PCs not covered under SA, thin clients or other clients that cannot run a full Windows OS, customers can purchase VDA for $100 per device/year, a $10 decrease from the previous VECD license price.
• Roaming use rights allows users to be able to access their virtual desktops from secondary devices like home PCS, kiosks and internet cafes without additional licensing costs.
