Support for interrupt remapping should be now available (kernel has been recompiled with but is there any way to check if it's available ?). I tried to do what you say in step 2 (num_vfs=1 and probe_vf=0) but it doesn't change anything. I also tried num_vfs=2 and probe_vf=1 but nothing is better. N

Which VF did you map to the guest O/S? In your configuration, both HCAs will have the PF and the first VF running on the hypervisor, and the remaining VFs available for binding to guests. You have: mlx4_core :05:00.0: Enabling SR-IOV with 3 VFs <== PF pci :05:00.1: [15b3:1002] type 00 clas
