Accept forbidden traits in the processing of extra_specs, with the
format of:
trait:CUSTOM_MAGIC=forbidden
This will be transformed into required=!CUSTOM_MAGIC when the traits
are assembled into a request to GET /allocation_candidates.

Added support for forbidden traits to the scheduler. A flavor extra spec
|
|
is extended to support specifying the forbidden traits. The syntax of
|
|
extra spec is ``trait:<trait_name>=forbidden``, for example:
|
|
|
|
- trait:HW_CPU_X86_AVX2=forbidden
|
|
- trait:STORAGE_DISK_SSD=forbidden
|
|
|
|
The scheduler will pass the forbidden traits to the
|
|
``GET /allocation_candidates`` endpoint in the Placement API to include
|
|
only resource providers that do not include the forbidden traits. Currently
|
|
the only valid values are ``required`` and ``forbidden``. Any other values
|
|
will be considered invalid.
|
|
|
|
This requires that the Placement API version 1.22 is available before
|
|
the ``nova-scheduler`` service can use this feature.
|
|
|
|
The FilterScheduler is currently the only scheduler driver that supports
|
|
this feature.
