Hi, I have just compiled and installed Xen 4.4-unstable changeset 27262 and Linux kernel 3.11.0-rc1. My Windows 7 Ultimate HVM domU configuration file is as attached. I tried to passthrough the onboard Intel HD Graphics 4600 IGD to Windows 7 Ultimate HVM domU. However, there are only 16 colors on the monitor. Please refer to the following screenshots. http://i.imgur.com/AVVPQFs.jpg http://i.imgur.com/390ORY0.jpg http://i.imgur.com/ihc0bR0.jpg http://i.imgur.com/FlNhjum.jpg http://i.imgur.com/sMrBKCq.jpg Please advise. Thank you very much. -- Yours sincerely, Singapore Citizen Mr. Teo En Ming (Zhang Enming)
