Yes. Fedora 19 HVM domU does start if I disable gfx_passthru and remove 
the IGD from the pci = [ ] list.

Although Fedora 19 HVM domU with VGA passthrough cannot start, Debian 
7.1.0 amd64 HVM domU with VGA passthrough can start. In Debian 7.1.0 
amd64 HVM domU with VGA passthrough, Intel HD Graphics 4600 is listed in 
lspci -vvv. Please refer to lspci.txt. It is strange that no kernel 
module is being loaded for Intel HD Graphics 4600. There is no "Kernel 
driver in use" statement after VGA compatible controller: Intel 
Corporation Haswell Integrated Graphics Controller (rev 06) (prog-if 00 
[VGA controller]).

No kernel driver is seen in lsmod. Please refer to lsmod.txt

When I tried to load the kernel module by executing "modprobe i915", it 
complains "no such device".

ERROR: could not insert 'i915': No such device

So is my Intel HD Graphics 4600 VGA Passthrough to Debian 7.1.0 amd64 
HVM domU considered successful since the i915 driver cannot be loaded?

Thank you very much.
