Subject: [questions] about using vfio to assign sr-iov vf to vm
Date: Thu, 14 Aug 2014 16:22:26 +0800	[thread overview]
Message-ID: <201408141622244965425@sangfor.com> (raw)

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
