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?

Maybe tie a knot between vhost-net scalability tuning: threading for many VMs
and vhost: Add polling mode is a good marriage,
because it's more possibility to get work to do with less polling time, so less
cpu cycles waste.

check /sys/module/kvm_intel/parameters/ple_gap, if non-zero(0), ple is
enabled, zero means ple is disabled.
