My server has 4 PCI slots, their addresses are 0000:04:00.0,
0000:05:00.0, 0000:41:00.0, 0000:42:00.0.
I want to pass 4 gpus to vms via vfio, each of vms has one gpu.
Vms worked fine when I passed 0000:04:00.0 and 0000:05:00.0 to
vms or passed 0000:41:00.0 and 0000:42:00.0 to vms.
But vms which used 0000:41:00.0 and 0000:42:00.0 had no output to
the screen and I could not ping vm's ip when I passed 0000:04:00,
0000:41:00.0 and 0000:42:00.0 to vms, but vm which used
0000:04:00 worked fine.
I got the same result when I passed 0000:05:00, 0000:41:00.0 and
0000:42:00.0 to vms : vm with 0000:05:00 worked fine and vms
which used 0000:41:00.0 and 0000:42:00.0 hanged.
When I define 0000:04:00.0 and 0000:05:00.0 as group A,
0000:41:00.0 and 0000:42:00.0 as group B, the result is :
1. Vms work fine When I just pass group A or group B to vms.
2. Just group A works fine when the gpus that I pass to vms
contain group A and B.
In case 2, vms work fine when I used '-vga cirrus' instead of
'-vga none'. But I get code 12 from graphics card in Device
Manager of windows 7. And this is not what I want, I just want to
use the graphics card in the host, so I should use '-vga none'.
It also worked fine when I remove vga passthrough or just pass
0000:41:00.1(the hdmi audio of graphics card) to vm.
I got no error output in qemu monitor.
How can I solve this probem ?
