Bug description:
Bug Description:
================
Steps to reproduce:
====================
$ nova hypervisor-list
+--------------------------------------+----------------------+--------------------+----------------------+
| ID | Hypervisor hostname | State
| Status |
+--------------------------------------+----------------------+--------------------+----------------------+
| e517e75b-d57c-45b2-af41-6be2fed536c6 | Openstack-VirtualBox | up
| enabled |
+--------------------------------------+----------------------+--------------------+----------------------+
Step 1: Add host into freepool
$ blazar host-create Openstack-VirtualBox
$ blazar host-list
+----+---------------------+-------+-----------+----------+
| id | hypervisor_hostname | vcpus | memory_mb | local_gb |
+----+---------------------+-------+-----------+----------+
| 1 | Openstack-VirtualBox| 4 | 11941 | 91 |
+----+---------------------+-------+-----------+----------+
Step 2: Create a lease
$ blazar lease-create --reservation
resource_type=virtual:instance,vcpus=1,memory_mb=1024,disk_gb=20,amount=1,affinity=False
--start-date "2018-08-27 12:59" --end-date "2018-08-27 13:55" lease-1
nova_api database entries related to aggregates:
Blazar creates aggregate with id=18
mysql> select * from aggregates;
+---------------------+------------+----+--------------------------------------+--------------------------------------+
| created_at | updated_at | id | uuid
| name |
+---------------------+------------+----+--------------------------------------+--------------------------------------+
| 2018-08-13 06:49:37 | NULL | 1 |
2a7d838f-4e42-48af-a9a9-faf3f29e3c96 | freepool |
| 2018-08-29 13:43:15 | NULL | 18 |
88c37cc5-373a-4da5-820f-508d25f00903 | 8c85522a-cc39-4a0d-a5ca-4de92e4d2c1f |
+---------------------+------------+----+--------------------------------------+--------------------------------------+
Blazar adds aggregate with aggregate_id=18, to host at the time of
lease-start event.
mysql> select * from aggregate_hosts;
+---------------------+------------+----+-----------------------+--------------+
| created_at | updated_at | id | host |
aggregate_id |
+---------------------+------------+----+-----------------------+--------------+
| 2018-08-29 13:34:46 | NULL | 32 | Openstack-VirtualBox |
1 |
| 2018-08-29 13:39:05 | NULL | 34 | Openstack-VirtualBox |
18 |
+---------------------+------------+----+-----------------------+--------------+
Step 3: Create a server: Please specify the flavor of the reservation and
group_id as a scheduler hint.
$ openstack server create --flavor 03067174-2a5e-43f7-baf7-037aac23b4ef
--image cirros-0.4.0-x86_64-disk --network 42d6f419-b445-40a6-b542-e8a502c6ae64
--hint group=09389292-6639-48d6-9709-045061f42ebf instance-1

ERROR state.: NoValidHost_Remote: No valid host was found. There are not enough
hosts available.
'AggregateInstanceExtraSpecsFilter' returns 0 hosts because at[1]
host_state.aggregates is not returning aggregate with metadata created by
Blazar. Lately, this patch [2] was merged in which
HostManager._get_aggregates_info method, the host is converted into lower case
and then it finds aggregates for that host in host_aggregates_map. But if the
compute host name is in uppercase, it doesn’t add the host in
host_aggregates_map in lowercase in _update_aggregates method hence
_get_aggregates_info method doesn’t return the aggregate associated with the
requested host.
Expected Result: Instance should be booted on the host "Openstack-VirtualBox"
Actual Result: NoValidHost_Remote: No valid host was found
