The 4.14 kernel is sufficiently old in the tooth (Ubuntu 18.04 uses 4.15, RHEL 7.x has likely backported the fixes) that there are likely not a great deal of users that could still use this broken feature if they wanted to. Drop support for it almost entirely, retaining only a warning to prevent accidental use. Change-Id: Iad76bce128574dc2f86998ccf2a9c5e799c71313 Signed-off-by: Stephen Finucane <stephenfin@redhat.com>

Intel CMT perf events - ``cmt``, ``mbmt``, and ``mbml`` - are no longer
|
|
supported by the ``[libvirt] enabled_perf_events`` config option. These
|
|
event types were broken by design and are not supported in recent Linux
|
|
kernels (4.14+).
