[Qemu-devel] Questions about GPU passthrough + multiple PCIE switches on host |

Hi folks,
I have 8 GPU cards needed to passthrough to 1 vm.
These cards are placed at 2 PCIE switches on host server, in case there
might be bandwidth limit within a single bus.
So what is the correct QEMU bus parameter if I want to achieve the best
performance. The QEMU's pcie.0/1 parameter could really reflect to the
actual physical device?
Thanks,
Bob
