Wei, I was not aware that XenClient sported such features, I would be more interested if I could find pricing on XenDesktop. Unfortunately they want me to go through a sales call process, which I believe means expensive. Perhaps when their distribution process allows for online purchases I may reconsider. It is at least good to know that they have specialized ATI features. Teo, I will be sure to post a video when I complete my re-installation. When booting an HVM it goes through a POST process, then the Windows 7 loading screen, I do not see any of this on my monitor. However, I can see it through a VNC connection. I only get video after Windows 7 has loaded, generally at the User Login menu. The way I understood it was my VGA Passthrough is a secondary GPU not the primary, though I am unaware of any specific benefits to make it the primary card. As for Xen 4.2 Unstable patches, David's blog has numerous posts compatible with different Xen 4.2 unstable revisions. The latest full guide seems to be for revision 24869: http://www.davidgis.fr/blog/index.php?2012/02/22/884-xen-42-the-way-to-compile-xen-has-changedrevision24869 On Fri, Mar 30, 2012 at 12:48 AM, Teo En Ming (Zhang Enming) < singapore.mr.teo.en.ming@gmail.com> wrote: > On 30/03/2012 05:29, Casey DeLorme wrote: > > David, > > XenServer VGA Passthrough requires a paid/licensed copy, which costs > $2500, a bit out of my price range for experimentation.
