So now I am working on a project that will need to use 3 vm with 3 gpu that will need to passthrough. The first vm passthrough is fine and displayed normal on monitor, but the second vm cannot passthrough keep black screen no display.
If i install splashtop on the second vm with the passthrough Windows booted fine and i can install the nvidia driver but after reboot device manager will show this Windows has stopped this device because it has reported problems. (Code 43) and no display from monitor.
Tried:
tried Emulated (QEMU64)/Host passthrough
Using (2,3,4,5,6)gb ram
Using CPU 0 to boot
Dump GTX750 rom to boot
HW is:
CPU: R7 1800x
MB: ASUS CROSSHAIR VI HERO
RAM: 16GB DDR4
HVM: Enabled
IOMMU: Enabled
GPU: GT630 for unraid
R9 280X first VM
GTX750 second VM
GT730 third VM
Using PCIe ACS Override setting to split IOMMU grouping
