commit a2d0b8d1b0954c6fdc622dda8fe8777e41566d92 Author: Eli Qiao <[email protected]> Date: Tue Sep 6 11:51:29 2016 +0800 Libvirt: Correct PERF_EVENTS_CPU_FLAG_MAPPING History: libvirt 1.3.3 had added perf event support for cmt, mbmt, mbml support when we landing the spec https://blueprints.launchpad.net/nova/+spec/support-perf-event . For the event cmt, mbmt, mbml, we requires that libvirt to expose some some specify cpu features, but libvirt 2.0.0 only has that expose merged `cpu_map.xml: add cmt/mbm feature to x86 (Qiaowei Ren)`, the capabilities changed to: <feature name='mbm_total'/> <feature name='mbm_local'/> <feature name='cmt'/> Need to adopt this to let nova driver discover these features when enable cmt, mbmt, mbml event. That is to say: even libvirt 1.3.3 has support perf event, but nova cannot get noticed since libvirt don't expose cpu features until 2.0.0. This patch bump MIN_LIBVIRT_PERF_VERSION to 2.0.0, see: https://libvirt.org/formatdomain.html#elementsPerf Closes-Bug: #1620445 Change-Id: Ie896cfd478f4528903ca5dd56c61680837b646b7 ** Changed in: nova Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo!
