Title:
ComputeCapabilitiesFilter failed to work with
AggregateInstanceExtraSpecsFilter
Status in OpenStack Compute (nova):
Invalid
Bug description:
Currently, ComputeCapabilitiesFilter returns false if 'extra_specs'
can't retrieve in the host state. And,
AggregateInstanceExtraSpecsFilter also use extra_specs to create new
instance in a host aggregate. The problem is they failed to select any
destinations, when the key is in non-scope format. As is shown in,
https://github.com/openstack/nova/blob/master/nova/scheduler/filters/compute_capabilities_filter.py#L77.
For example, we may want to use host aggregate to create a new
instance in some servers with specified properties. So we create a new
flavor and set 'extra_specs' to {"property": "balabala"}，the
computecapabilitiesfilter will return false. In this situation,
ComputeCapabilitiesFilter failed to work with
AggregateInstanceExtraSpecsFilter
I think we'd better check the capabilities only when the key for the
filter is scope format in capabilities scope (i.e.
capabilities:xxx:yyy), rather than non-scope format (i.e. no :
contained).
