Resize on same host in multiple-compute nodes environment not possible

[Martin Ivanov]

Hi,

On Ocata release, nova 15.0.7( Libvirt+KVM) its not possible to resize working instance on the same host, in multiple compute nodes environment
In nova.conf is set:
allow_migrate_to_same_host = True

but this is not enough. Resize in Dashboard returns:
Error: No valid host was found.

2017-12-08 14:35:36.127 18389 INFO nova.filters [req-21f0e039-f92a-41d7-88c3-fbecd9b46c4b a719e1fa1583410e84a60584b057854f 76544321203c4ea5b40651daf4505f35 - - -] Filtering removed all hosts for the request with instance ID 'cb76c5cc-3b0b-40eb-ba54-05b21331b693'. Filter results: ['RetryFilter: (start: 1, end: 1)', 'AvailabilityZoneFilter: (start: 1, end: 0)']

It is not possible to specify:
scheduler_default_filters = AllHostsFilter
as this will ignore Availability zone specified per each instance launch.

Please advice if this is expected behavior and if can be fixed.

Can you provide the full image and flavor information (including image properties and flavor extra-specs)?

There is a similar bug report.
