Looking more into this, using nomodeset triggers this workaround: http://cgit.freedesktop.org/xorg/driver/xf86-video-qxl/tree/src/qxl_driver.c#n819 /* fake transform support, to allow agent to switch crtc mode */ /* without X doing checks, see rrcrtc.c "Check screen size */ /* bounds" */ xf86RandR12SetTransformSupport (pScreen, TRUE); which nicely points at the bit of code in the X server which causes the X error in the RHEL6/kms guest situation: http://cgit.freedesktop.org/xorg/xserver/tree/randr/rrcrtc.c#n1148 Christophe
