Pardon me if I should create this mail thread in other mail lists.
I just tried to assign the network card to the DomU and the device
can be identified in it. But it is not the same case with the VGA
card.
Thanks,
Miao

Hi all, sorry to bother.
I'd like to ask how to enable HVM based vga-passthru of the
secondary graphics adapter on Xen-4.1-testing?
Now DomU only shows the qemu console after started.
My box's configuration is i7 965 + DX58SO + 2* Nvidia 9800 GTX. I
use CentOS 5.6, checkout xen-4.1-testing.hg and jeremy's kernel
(2.6.32.43).
I am trying to enable vga-passthru on my box by patching the first
four patches according to
http://lists.xensource.com/archives/html/xen-devel/2010-05/msg00441.html.
It seems all hunks are patched successfully. In order to fix the
compile errors. I modified the pass-through patch to make the hunk
#1 to be placed in the middle of the pass-through.c file.
I attached the domU config file (winxp), dom0 lspci output
(lspci), xl dmesg output (xldmesg). The pci of the secondary
graphics card is 03:00.0
Grub config:
title CentOS (2.6.32.43-xen)
root (hd0,0)
kernel /boot/xen-4.1.gz dom0_mem=1024M loglvl=all
guest_loglvl=all iommu=1
module /boot/vmlinuz-2.6.32.43 root=LABEL=/ ro
xen-pciback.hide=(03:00.0)
module /boot/initrd-2.6.32.43.img
Thanks a lot!
