I sorry that I give the wrong info in last email and here is the IOMMU
Group about 0000:41:00.0 :
IOMMU Group 40 41:00.0 VGA compatible controller [0300]: NVIDIA Corporation
GK208 [GeForce GT 710] [10de:1281] (rev a1)
IOMMU Group 40 41:00.1 Audio device [0403]: NVIDIA Corporation GK208
HDMI/DP Audio Controller [10de:0e0f] (rev a1)
I have other test in this case:
I have two graphics card bios rom files:
1. One* ( rom A )* is export by :
# echo 1 > /sys/bus/pci/devices/0000\:41\:00.0/rom
# cat /sys/bus/pci/devices/0000\:41\:00.0/rom > /root/nvidia/gt710.rom
# echo 0 > /sys/bus/pci/devices/0000\:41\:00.0/rom
This is which I use now and mention in my first email.
2. Aother *( rom B ) *is exported by gpu-z in windows 7 :
/root/nvidia/gpuz.rom
As I write in my first email.
VM had no output to screen and I can not ping the VM with
/root/nvidia/gt710.rom. (Which works fine when I just pass group A or group
B to vm.)
And the newest test results are :
(VM use 0000:41:00.0 while another using 0000:05:00.0)
1. VM work fine when I use *rom B* and installed *cento7* to VM .
2. VM had no output to then screen, but I can ping the VM when I use *rom
B* and installed *window7* to VM, the gpu return code 43 in Device
Manager. (Is that mean I use a wrong rom file ? )
3. VM work fine when I start VM with *ovmf *in *windows 10 *(boot from
*UEFI*).
And here are my questions are:
1. Is this problems about the rom file of gpu?
If the answer is 'yes' and :
2. How can I get the correct and useful rom file ? I want to use window7 in
guest, but UEFI is unfriendly to windows7.
3. Why I can start my vm when I pass group B only and use *rom A*, but I
can not start vm when I pass group A and B to vms and also use *rom A* ?
Regards
John
