Thank you for your reply and sorry for my late response.

I attach the grub configration file, HVM domU configuration file, and
kernel configuration file.
I am trying with Xen 4.2.2 now, so xen 4.2.2 is set in the grub file.


I have installed xen and dom0 kernel by referring to these pages and so.
   - http://wiki.xen.org/wiki/XenPCIpassthrough
   - http://wiki.xen.org/wiki/Xen_VGA_Passthrough
   -
http://xen.1045712.n5.nabble.com/Latest-Xen-Linux-Kernel-and-VGA-Passthrough-Tutorials-td5718127.html

I have built dom0 kernel by these commands.
   $ make menuconfig
   $ make -j8
   # make modules_install install

In menuconfig I checked 4 options and the others were default.
   1. Processor type and features ->
      Linux guest support ->
      Enable paravirtualization code ->
      Xen guest support
   2. Power management and ACPI options ->
      ACPI (Advanced Configuration and Power Interface) support ->
      Deprecated /proc/acpi files
   3. Device Drivers ->
      Network device support ->
      Xen backend network device
   4. Device Drivers ->
      Block Devices ->
      Xen block-device backend driver

And I have built Xen by these commands.
   $ make world
   # make install

For passthrough vga device, I use these commands.
   # echo 0000:00:02.0 > /sys/bus/pci/devices/0000:00:02.0/driver/unbind
   # echo 0000:00:02.0 > /sys/bus/pci/drivers/pciback/new_slot
   # echo 0000:00:02.0 > /sys/bus/pci/drivers/pciback/bind


Best regards,
Kento
