Haha, since the discussion moved to XCP and this is not really my area i didn't read your last message. The patch from the thread you mentioned is basically the same then the one I provided.. Did you also tried to do secondary passthrough with the patch applied? Cause primary passthrough didn't work for me either with the patch, but secondary was fixed.. 2013/3/12 Matthias <matthias.kannenberg@xxxxxxxxxxxxxx>: > Hi, > > to fix the atikmeq.sys bug, you can try two things: > > 1) Use upstream qemu.
