Public bug reported: bug https://bugs.launchpad.net/nova/+bug/1970467 tracks removign the api blocks for operations with vdpa ports that currently work in the code now that they have been tested with real hardware. (cold migration, resize, shelve and evacuate)
This blueprint proposes completing the feature set by adding support for interface detach, suspend and hotplug live migrations. detach currently does not work because we do not parse the source device path form the dev attribute of the source element in the libvirt XML. https://review.opendev.org/c/openstack/nova/+/841016 suspend does not work because of how suspend currently detaches the vifs https://review.opendev.org/c/openstack/nova/+/841017 and hotplug live migration simple need vdpa to be added to the list of passthoug devices that need to be detached https://review.opendev.org/c/openstack/nova/+/841012 with these 3 small changes we can have feature parity with neutron sriov direct mode interfaces and enable all VM lifecycle operations. transparent vdpa live migration is out of scope of this blueprint as that requires additional feature development in qemu and the kernel. ** Affects: nova Importance: Undecided Assignee: sean mooney (sean-k-mooney) Status: Invalid ** Tags: libvirt live-migration pci ** Changed in: nova Status: New => Invalid -- You received this bug notification because you are a member of Yahoo!
