Citrix XenClient is undergoing testing as I write this. It is a Type 1 Hypervisor that will load on your desktop or laptop before any other software is loaded on your machine. This includes your Operating System, such as Windows XP, Windows Vista, or Windows7. Once loaded, OS's can run on top of XenClient in a virtualized container.
Can you run more than 1 Virtual Container at a time? The short answer is yes, the longer answer is "it depends". Depending upon the amount of memory you have in the client machine and depending upon how much memeory you have allocated for each Virtual Container, will determine if you can run more than 1 virtual machine or not. As time gets closer to the Public Launch of XenClient, we will receive more information as to recommended hardware. Once we have that information we will pass it along to you as quickly as possible. We do know however, that XenClient takes advantage of Intel's Vt-d technology found in vPro systems. So if this is a technology that you are looking to implement, vPro systems are the way to go.
Now I could spend more time describing to you the details of XenClient, but as they say, a picture is worth a thousand words. So I invite you now to click on the following url's, to see for yourself, a few of the features and benefits XenClient will offer to you. The following url's will take you to the Citrix website. The videos are only 2-3 minutes long, so if you can spare some time. Please view them now.
