commit b9858b2981fbdc52c0721d29cc15abce93371544 Author: Nikola Dipanov <ndipa...@redhat.com> Date: Thu Apr 7 18:53:52 2016 +0100 pci: Make sure PF is 'available' when last VF is freed We were adding the PF back to the pools but not setting the status properly. The reason this was not caught by tests is because tests were broken as well (we were using assertTrue instead of assertEqual which always passes). Change-Id: I62d4a810d8d7c4453865db0290029c269225c139 Closes-bug: #1567549 ** Changed in: nova Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1567549 Title: SR-IOV VF passthrough does not properly update status of parent PF upon freeing VF Status in OpenStack Compute (nova): Fix Released Bug description: Assigning an SR-IOV VF device to an instance when PFs are whitelisted too correctly marks the PF as unavailable if one of it's VFs got assigned. However when we delete the instance, the PF is not makred as available. Steps to reproduce: 1) Whitelist PFs and VFs in nova.conf (as explained in the docs) for example pci_passthrough_whitelist = [{"product_id":"1520", "vendor_id":"8086", "physical_network":"phynet"}, {"product_id":"1521", "vendor_id":"8086", "physical_network":"phynet"}] # Both pfs and vfs are whitelisted 2) Add an alias to assign a VF pci_alias = {"name": "vf", "device_type": "type-VF"} 3) Set up a flavor with an alias extra_spec $ nova flavor-key 2 set "pci_passthrough:alias"="vf:1" 4) Boot an instance with the said flavor and observe a VF being set to 'allocated' and a PF being set to 'unavailable' select * from pci_devices where deleted=0; 5) Delete the instance from step 4 and observe that the VF has been made available but the PF is still 'unavailable'. Both should be back to available if this was the only VF used.
