The libvirt driver now allows explicitly disabling CPU flags for
guests via the ``[libvirt]cpu_model_extra_flags`` config attribute.
This is possible via a ``+`` / ``-`` notation, where if you specify
a CPU flag prefixed with a ``+`` sign (without quotes), it will be
enabled for the guest, while a prefix of ``-`` will disable it. If
neither ``+`` nor ``-`` is specified, the CPU flag will be enabled,
which is the default behaviour.
Refer to the ``[libvirt]cpu_model_extra_flags`` documentation for
more information.
