Thanks Antonio, I added AggregateRamFilter in nova.conf of scheduler and restarted nova-scheduler service and updated aggregate.
nova aggregate-set-metadata id ram_allocation_ratio=2.08 and i can see that in nova aggregate-details 2 +----+---------------+-------------------+----------------+--------------------------------------------------------+ | Id | Name | Availability Zone | Hosts | Metadata | +----+---------------+-------------------+----------------+--------------------------------------------------------+ | 2 | overcommitted | second | 'node8' | 'availability_zone=second', 'ram_allocation_ratio=2.08' | +----+---------------+-------------------+----------------+--------------------------------------------------------+ but still scheduler log shows "Filter AggregateRamFilter returned 1 host(s)" " Filter RamFilter returned 0 hosts" and fails with error "instances:17 does not have 2048 MB usable ram, it only has 613.5 MB usable ram." Any idea?
