Does this actually work? The docs only describe setting the
metadata on the flavor, not as part of the boot command.
If you want to be able to pass it in as explicit hints then you need
to write a filter to cope with that hint- I was using it as an
example of the kind of relationship between hints and aggregate
filtering The more realistic example for this kind of attribute is to
make it part of the flavor and use the aggregate_instance_extra_spec
filter - which does exactly this kind of filtering (for overlapping
aggregates)
I'll admit that I don't have a lot of experience as an end-user of
OpenStack, so maybe that colours my judgement.
To me it seems quite limiting that if you want the scheduler to match
against multiple host aggregate extra specs then you need to create a
new flavor.
If a regular user could do something like what you specify in your
example, I think that would make a lot of sense.
