Hi all,<br>I'm running IGD pass through on xen and only get partial success.<br>Basically PVHVM guest works while HVM guest (windows, linux without pvops compiled in) does not. <br>I'm trying to figure out what's the missing piece in xen and need help from you experts.<br>
I managed to capture some logs for both passing && failing system.<br><br>not working<br>reg dump: <a href="http://pastebin.com/7vyG0biu">http://pastebin.com/7vyG0biu</a><br>dmsg: <a href="http://pastebin.com/svWG0LdY">http://pastebin.com/svWG0LdY</a><br>

I noticed some difference on register values and some failure on dmsg logs.<br>Could you help to identify the fatal ones so that I can dig into xen source?<br><br>Thanks,<br>Timothy<br>
