Added traits support to the scheduler. A new flavor extra spec is added to
|
|
support specifying the required traits. The syntax of extra spec is
|
|
``trait:<trait_name>=required``, for example:
|
|
|
|
- trait:HW_CPU_X86_AVX2=required
|
|
- trait:STORAGE_DISK_SSD=required
|
|
|
|
The scheduler will pass required traits to the
|
|
``GET /allocation_candidates`` endpoint in the Placement API to include
|
|
only resource providers that can satisfy the required traits. Currently
|
|
the only valid value is ``required``. Any other value will be considered
|
|
invalid.
|
|
|
|
This requires that the Placement API version 1.17 is available before
|
|
the ``nova-scheduler`` service can use this feature.
|
|
|
|
The FilterScheduler is currently the only scheduler driver that supports
|
|
this feature.
