Dear Yongjie and Xen developers,

I have compiled and installed the latest Xen 4.4-unstable changeset 
27305 and Linux kernel 3.10.3.

Although I did not get error code 43 for Intel HD Graphics 4600 IGD in 
device manager, I am still getting 16 colors only for the monitor!!!

How can I solve this problem?
