Dear David Techer and others,
I thought Intel H61 chipset and MSI motherboards officially don't
support VT-x and VT-d? There is no VT-d enabling option in MSI
motherboard BIOS.
I want to test Xen VGA passthrough for Windows 8 Consumer Preview
64-bit English HVM domU with my Intel DQ45CB motherboard and Intel
Pentium Dual Core E6300 2800 MHz.
By the way, I am using Linux kernel 3.3.0 Final. Should I use
PCIBACK or PCI-STUB? If I use pciback, what arguments should I parse
to the kernel command line in GRUB2? Please point me to the
documentation for kernel command line arguments in the linux kernel
source tree.
My graphics card: Palit NVIDIA Geforce 8400 GS PCI Express x16
SGD$44
Thank you very much.
Yours sincerely,
Teo En Ming (Zhang Enming)

You're welcome.
Keep in mind that if you are going to upgrade BIOS
for your motherboard, those values for your card may
changed.
I was in this situation last time BIOS was upgraded.
It does mean that those values will changed each time
you upgrade your motherboad BIOS but having thos values
changed after a BIOS upgrade could occur for a specific
upgrade.
Don't ask me why...I do not know.
So you will be well advised to heck those values for
each BIOS upgrade.
Moreover don't waste your time to test VGA
PassThrough for NVIDIA for Windows 7. For Windows 7 use
ATI.
I did my tests for playing with wine 1.4/1.5 on domU
Ubuntu Lucid 10.04.4 PV HVM (game like Crysis 2) and it
rocks :)
My configuration:
Manufacturer: MSI / Product Name: H61MU-E35 (MS-7680)
Bios version: V10.11
Dear David Techer,
Thank you.
I think the following command is sufficient.
dmesg | grep 01:00.0 | grep "pci.*mem"
Yours sincerely,

Hi Teo,

Corporation Device 0ca2 (rev a2)
root@gemini:~# dmesg|grep 02:00.0 |grep ' pci

Kind regards
Dear David Techer,
I have read through your article on Xen VGA
passthrough on
http://www.davidgis.fr.
It appears that the following command on your
blog doesn't work.
dmesg | grep 01:00.0 | grep BAR
The above command shows nothing at all. Is there
an alternative solution?
Thank you very much.
Yours sincerely,
Teo En Ming (Zhang Enming)
