features:
|
|
- |
|
|
The libvirt driver has been extended to support user configurable
|
|
performance monitoring unit (vPMU) virtualization.
|
|
This is particularly useful for real-time workloads.
|
|
A pair of boolean flavor extra spec and image metadata properties
|
|
``hw:pmu`` and ``hw_pmu`` have been added to control the emulation
|
|
of the vPMU. By default the behavior of vPMU emulation has
|
|
not been changed. To take advantage of this new feature, the operator
|
|
or tenant will need to update their flavors or images to define the
|
|
new property.
