Hi, all I'm using VFIO to assign intel 82599 VF to VM, now I encounter a problem, 82599 PF and its VFs belong to the same iommu_group, but I only want to assign some VFs to one VM, and some other VFs to another VM, ..., so how to only unbind (part of) the VFs but PF? I read the kernel doc vfio.txt, I'm not sure should I unbind all of the devices which belong to one iommu_group? If so, because PF and its VFs belong to the same iommu_group, if I unbind the PF, its VFs also diappeared. I think I misunderstand someting, any advises?
Thanks, Zhang Haoyu
