Dear Yongjie,

I am not sure what went wrong but error code 43 comes back again. All I 
did was to blacklist the i915, nouveau, and snd_hda_intel kernel 
modules, rebuild the initial ramdisk, and turn off gdm. Could you tell 
me what went wrong?

Could you share with us your full GRUB2 configuration and Windows 7 HVM 
domU configuration?

Thank you very much.
