Implementation Considerations for VMware App Volumes in a Citrix XenDesktop Environment

Citrix, VMware
App Volumes works well with both Citrix XenDesktop and Citrix XenApp, either individually or in a combined XenDesktop and XenApp implementation. The same AppStacks that attach to XenDesktop virtual desktops to deliver applications to users can also attach to XenApp servers to deliver applications. To learn more about using App Volumes in a XenApp environment, read Implementation Considerations for VMware App Volumes in a Citrix XenApp Environment. This paper focuses only on App Volumes in a XenDesktop environment

PernixData and Citrix Xendesktop

Citrix
Citrix XenDesktop mobilizes and secures Windows desktops so users can access them from any device. This reduces desktop costs, while maximizing control of content.  However, Citrix XenDesktop is very sensitive to latency. The slightest delay (or variations in delay) can cause poor and/or inconsistent desktop performance.  This makes storage bottlenecks a big threat to the success of XenDesktop deployments.  PernixData FVP™ software eliminates storage bottlenecks, making it a perfect complement to Citrix XenDesktop. By moving storage intelligence into hosts where the XenDesktop VMs reside, FVP lowers VDI latency by 10x–even under peak loads. In addition, FVP provides a cost-effective way of scaling out storage performance as your VDI deployment grows. How it Works FVP software is seamlessly deployed inside the hypervisor running XenDesktop VMs (e.g. VMware vSphere). No changes are…

SCCM 2012 Client install on Xendesktop Image

Citrix, Microsoft
I was having an online discussion with a friend this week about the correct way of installing the Microsoft SCCM 2012 client on a Xendesktop (MCS) golden image.  After doing some research there are conflicting actions with some blogs saying  "install it and that's it",  whilst others saying you must perform some additional work before closing  your image. I was intrigued to find the answer to this debate.  So I decided to test this in my Xendesktop lab myself so I decided to install SCCM 2012. To cut a long story short what I did notice was that if you deployed desktops after just installing the client you would start to get issues with "Bad MIF" files in your environment.  If you checked the folder location C:Program FilesMicrosoft Configuration Managerinboxesauthdataldr.boxBADMIFSMajorMismatch you will see that the machines that are delivered by Xendesktop will start creating these files. So trying…

Webcams not enumerated in Xendesktop Session

Citrix
I have come across an issue recently whereby certain webcams are not enumerated correctly in a Xendesktop session. The issue appears to be with certain webcams and there lack of support for switching to the default resolution of 352 x 288. By modifying a certain key within the registry you can fixed the setting to a more common resolution ie 320 x 240. The registry key in question is the HKEY_CURRENT_USERSoftwareCitrixHDXRealTime you will need to create the following values:- Name: DefaultWidth Type: REG_DWORD Data: 320 (decimal) Name:DefaultHeight Type: REG_DWORD Data: 240 (decimal) Once this is added you should see that the webcam gets redirected within the session without any problems.

Multiple Launch Prevention in Citrix Receiver for Web

Citrix
One of the frequently asked questions for Receiver for Web is multiple launch prevention. This is supported in Receiver for Web. When you click on an application or desktop icon to launch it, a spinner is displayed and any clicks on the same icon are ignored while the spinner is spinning. Hence user cannot unintentionally launch multiple instances of the same application/desktop. Out of the box, the time period for the spinner is fixed for three seconds. In StoreFront 2.5, this can be modified by a simple customization. Just insert the following code snippet into custom.script.js in the contrib folder under the Receiver for Web site: $(document).ready(function() {      CTXS.Resources.multiClickTimeout = 10; }); This code snippet changes the duration to 10 seconds. You should alter the number according to your requirement.…

XenDesktop Error: The hosting infrastructure could not be reached at the specified address

Citrix, VMware
When trying to create a XenDesktop group that is using ESX 4/5 as the hosting infrastructure, or you've had to reinstall VMware vCentre you may receive the following error message: "The hosting infrastructure could not be reached at the specified address." or there is no virtual desktop activity i.e. power on/off as virtual desktops are being used when viewed in vCentre recent activity The reason for this is because VMWare, vSphere, and the ESX host are configured to redirect http traffic to https by default.  Because the default certificate on ESX does not match the name of the server, it generates an error. I found and used the following to rectify the issue:- Log on to the vCenter Server system as the Windows Administrator of the machine. Locate the vCenter proxy.xml…
