I have an install that's been working decently with one passthrough GPU based off the wiki, so I took out the old GPU and installed two identical new ones. Now the VM doesn't boot, seems to stick before UEFI loads.
I removed PCIE passthrough for the second, and then for the first, respectively (they are 01:00.0 and 03:00.0). Both work as expected in the VM when enabled individually.
It seems that they both have the same IRQ assignment and I can't find a way to change this outside of perhaps going to bios and checking to reassign there. IRQ remapping is enabled `DMAR-IR: Enabled IRQ remapping in x2apic mode`, but perhaps given the two new GPUs are the same make and model it could be getting confused?
There's only two x16 slots on this board so changing cards to different PCIE slots isn't a possibility.
Outside of that, I'm not sure what other settings I could look at to determine conflicts. Anyone know what other settings to look at that relate specifically to multiple GPUs? All hardware is consumer-grade.
