Comment 6 for bug 1892361

what release of openstack was this observed in?

vnic_type=direct was allowed to select PF in older relesase and its still valid for it to select type-pci i belive i will have to look.

change that added support for vnic-type=direct-phsyical broke backwards compatiabliy with the old behaver of direct mean vf or pf but type-pci may be an expction to that.

and yes the assment in https://bugs.launchpad.net/nova/+bug/1892361/comments/3
is correct this bug will only be hit if you updated the firmware of bios config of a device that was previously not capable of support sriov to one that is.

this could also happen if you replaced a non sriov vf capable nic with one that does
the workaround for that case is to remove the nic, start the agent, add an nic and start the agent.
