I found that if we only passthrough one VF to guest, the mac is = the same as it in host, but when passthrough 2 or more VFs, sometimes only the first VF use the same mac as it in host, other VFs' mac are random; sometim= es all the VFs' mac are random. --=20 You may reply to this email to add a comment.
