  1. All: Community open discussion.
Q&A: 
Q1: Read-Only SR-IOV register settings are from BIOS.
Q2: One physical SR-IOV device may have several PFs for each function, but one function only has one PF, which is defined in the device driver. 
Q3:Default VF BAR memory is  4K bit, but could be changed by System Page Size.
Q4.SOS will manage and pass through related VFs to each VMs.
Q5.ACRN config_tool doesn’t support configuring VFs to VMs, it is done in SOS by command. 
Q6. The maximum number of VF is Read-only in PCI config space, which is hard-wired by each device and driver. The real VFs number could be configured in SOS by command.
