Title:
'openstack allocation candidate list' returns non-compute nodes
Status in OpenStack Compute (nova):
Expired
Bug description:
Description
===========
'openstack allocation candidate list ' command returns a list nodes that can
meet the resource allocation requests, even some of them are not compute nodes.
For example, user requests to create a VM with 50G mem, 60G disk and 6
CPUs, placement API returns two nodes:
$ openstack allocation candidate list --resource MEMORY_MB=51200 --resource
DISK_GB=60 --resource VCPU=6 --os-placement-api-version 1.10
+---+-----------------------------------+--------------------------------------+-----------------------------------------------+
| # | allocation | resource provider
| inventory used/capacity |
+---+-----------------------------------+--------------------------------------+-----------------------------------------------+
| 1 | VCPU=6,MEMORY_MB=51200,DISK_GB=60 |
6eccd190-1d8c-488c-9db7-0cb49d08bdc7 |
VCPU=0/1280,MEMORY_MB=0/385992,DISK_GB=0/1831 |
| 2 | VCPU=6,MEMORY_MB=51200,DISK_GB=60 |
27073646-35fc-4af8-9484-c52504d30a63 |
VCPU=0/1280,MEMORY_MB=0/385993,DISK_GB=0/1831 |
+---+-----------------------------------+--------------------------------------+-----------------------------------------------+
$ openstack resource provider list |grep -E
"6eccd190-1d8c-488c-9db7-0cb49d08bdc7|27073646-35fc-4af8-9484-c52504d30a63"
| 6eccd190-1d8c-488c-9db7-0cb49d08bdc7 | openstack-4.maas | 1 |
6eccd190-1d8c-488c-9db7-0cb49d08bdc7 | None |
| 27073646-35fc-4af8-9484-c52504d30a63 | openstack-5.maas | 1 |
27073646-35fc-4af8-9484-c52504d30a63 | None
But openstack-4 and openstack-5 are not compute nodes. Since VM can
only be hosted on compute node, I think 'allocation candidate list '
should only return the schedulable compute nodes.
Steps to reproduce
==================
see above
Expected result
===============
'allocation candidate list ' should only return the schedulable compute nodes.
Actual result
=============
'allocation candidate list ' returns non-compute nodes.
