Title:
PCI passthrough documentation does not describe the steps necessary to
passthrough PFs
Status in OpenStack Compute (nova):
Fix Released
Status in OpenStack Compute (nova) train series:
Fix Released
Bug description:
This came up on IRC [1]. By default, nova will not allow you to use PF
devices unless you specifically request this type of device. This is
intentional behavior to allow users to whitelist all devices from a
particular vendor and avoid passing through the PF device when they
meant to only consume the VFs. In the future, we might want to prevent
whitelisting of both PF and VFs, but for now we should document the
current behavior.
