+++ This bug was initially created as a clone of Bug #1576799 +++ Backport the following commit to RHOS-12: commit facde6cad8bc7ce0fd4d251f86550a7f648a5a13 Author: Kashyap Chamarthy <kchamart> Date: Sat Apr 28 18:55:25 2018 +0200 libvirt: Make `cpu_model_extra_flags` case-insensitive for real When we introduced `cpu_model_extra_flags` config attribute (in commit: 6b601b7 -- "libvirt: Allow to specify granular CPU feature flags"), we said it was case-insensitive; but unfortunately I missed to _really_ make it so (despite proposing code for it in one of the revisions). Address that mistake by making `cpu_model_extra_flags` case-insensitive for real, from Nova's point of view. NB: Internally, this patch is normalizing 'extra_flags' to _lower_ casing -- because CPU flags _must_ be lower case from libvirt's point of view. Nova must honour that; otherwise, launching instances with an upper case CPU flag, 'FOO', will fail with: "libvirtError: internal error: Unknown CPU feature FOO".
