Specs: - Base: https://review.openstack.org/601596 - Libvirt: https://review.openstack.org/622893 Patches: https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:m... Summary/agreements: - Support persistent memory in units of "namespaces" with custom resource class names. - Namespaces to be pre-carved out by admin/deployer (not by Nova). - Custom RC names mapped to byte sizes via "conf" [1] so virt driver can know how to map them back to the real resources. - "Ignore NUMA for now" (sean-k-mooney will have to tell you what that means exactly). - Spec needs to list support-or-not for all instance lifecycle operations. - Keep one spec for base enablement and one for libvirt, but make sure the right bits are in the right spec. efried [1] There has been a recurring theme of needing "some kind of config" - not necessarily nova.conf or any oslo.config - that can describe: - Resource provider name/uuid/parentage, be it an existing provider (the compute root RP in this case) or a new nested provider; - Inventory (e.g. pmem namespace resource in this case); - Physical resource(s) to which the inventory corresponds; - Traits, aggregates, other? As of this writing, no specifics have been decided, even to the point of positing that it could be the same file for some/all of the specs for which the issue arose.
