Hi Eyal, Yes, currently it's not possible to distinguish between Physical Functions that share the same vendor/product id on a host. We will need to wait until the following patch is merged: https://review.openstack.org/#/c/363884 then we will be able to whitelist these according their pci addresses. For an even more fine grained control, we will need to wait for the following spec to be implemented in the Ocata release: https://review.openstack.org/#/c/350211 Thanks, Vladik Another reason we'll need the PCI address control is that if a system has only SR-IOV cards of the same make/model but only a few are being used for guests and the others are used for control plane/management/storage/etc., it is very possible that openstack will allocate the device for openstack use - potentially disconnecting the compute node from the cloud. I think we need a some kind of release note strongly warning users to NOT use PFs if they are using similar NIC hardware for multiple purposes on their hypervisor nodes. An attempt to make it backported on Newton here: https://review.openstack.org/#/c/393752/ *** Bug 1391680 has been marked as a duplicate of this bug. *** Hi, I have verified the following bug. I was able to boot up two VM's which is sharing the same vendor/product id on the host.
