One of the new features brought by XenApp 5 Feature Pack 2/XenApp 6 and XenDesktop 4 is the use of VM Hosted Apps. In this document we will see how we can set up VM Hosted Apps in our organization, is an integration between XenDesktop and XenApp, it will be used to run applications that are not compatible with Terminal Server or server operating systems or simply if we want to isolate them on computers with OS. Windows XP, View or 7. In a virtual desktop that we have with XenDesktop, we will install this application and create a group of desktops in XenDesktop where we will indicate that they are VM hosted apps (or hosted application VM). We will integrate both environments through Web Interface and it will be totally transparent for users.
