Hi Gordan,

According to Yongjie from Intel, he did not apply any patches to his Xen 
4.3-unstable changeset 26666. Anyway, I am using Intel HD Graphics 4600, 
so David Techer's NVIDIA patches don't apply to me.
Could you check my configuration files to see if there are any mistakes? 
Especially /etc/grub.d/40_custom.
