[Resending for a colleague who's not on openstack-dev-- SL.] Yeap, because of the bug [#1677217] in the standard AggregateImagePropertiesIsolation filter, we have written a custom Nova scheduler filter.
The filter AggregateImageOsDistroIsolation is a simplified version the AggregateImagePropertiesIsolation, based only on the 'os_distro' image property. https://github.com/valerytschopp/nova/blob/aggregate_image_isolation/nova/scheduler/filters/aggregate_image_os_distro_isolation.py [#1677217] https://bugs.launchpad.net/nova/+bug/1677217 Cheers, Valery On 29/04/18, 23:29 , "Ed Leafe" <e...@leafe.com> wrote: > On Apr 29, 2018, at 1:34 PM, Artom Lifshitz <alifs...@redhat.com> wrote: >> >> Based on that, we can definitely say that SameHostFilter and >> DifferentHostFilter do *not* belong in the defaults.
