Hi Chen Zheng, I was not able to reproduce your problem today. Here is
what I did:
1. create one controller and two compute (zhaoqin-RHEL-GPFS-tmp and
zhaoqin-RHEL-GPFS-tmp1)
2. create two host groups
[root@zhaoqin-RHEL-GPFS-tmp chaochin]# nova aggregate-details gpfs
+----+------+-------------------+----------------------------+---------------------------------------------------+
| Id | Name | Availability Zone | Hosts | Metadata
|
+----+------+-------------------+----------------------------+---------------------------------------------------+
| 1 | gpfs | nova | [u'zhaoqin-RHEL-GPFS-tmp'] | {u'gpfs':
u'true', u'availability_zone': u'nova'} |
+----+------+-------------------+----------------------------+---------------------------------------------------+
[root@zhaoqin-RHEL-GPFS-tmp chaochin]# nova aggregate-details gluster
+----+---------+-------------------+-----------------------------+------------------------------------------------------+
| Id | Name | Availability Zone | Hosts | Metadata
|
+----+---------+-------------------+-----------------------------+------------------------------------------------------+
| 2 | gluster | nova | [u'zhaoqin-RHEL-GPFS-tmp1'] | {u'gluster':
u'true', u'availability_zone': u'nova'} |
+----+---------+-------------------+-----------------------------+------------------------------------------------------+
3. create two falvors
[root@zhaoqin-RHEL-GPFS-tmp chaochin]# nova flavor-show gpfs
+----------------------------+--------------------+
| Property | Value |
+----------------------------+--------------------+
| name | gpfs |
| ram | 64 |
| OS-FLV-DISABLED:disabled | False |
| vcpus | 1 |
| extra_specs | {u'gpfs': u'true'} |
| swap | |
| os-flavor-access:is_public | True |
| rxtx_factor | 1.0 |
| OS-FLV-EXT-DATA:ephemeral | 0 |
| disk | 1 |
| id | 10 |
+----------------------------+--------------------+
[root@zhaoqin-RHEL-GPFS-tmp chaochin]# nova flavor-show gluster
+----------------------------+-----------------------+
| Property | Value |
+----------------------------+-----------------------+
| name | gluster |
| ram | 64 |
| OS-FLV-DISABLED:disabled | False |
| vcpus | 1 |
| extra_specs | {u'gluster': u'true'} |
| swap | |
| os-flavor-access:is_public | True |
| rxtx_factor | 1.0 |
| OS-FLV-EXT-DATA:ephemeral | 0 |
| disk | 1 |
| id | 11 |
+----------------------------+-----------------------+
4. VM can be scheduled to the host group specified by the flavor
[root@zhaoqin-RHEL-GPFS-tmp chaochin]# nova boot --image dcc42858-f4f8
-45ef-b2ba-33a66c806afc --flavor gluster gluster-vm
[root@zhaoqin-RHEL-GPFS-tmp chaochin]# nova boot --image dcc42858-f4f8
-45ef-b2ba-33a66c806afc --flavor gpfs gpfs-vm
[root@zhaoqin-RHEL-GPFS-tmp nova]# nova show gluster-vm | grep hostname
| OS-EXT-SRV-ATTR:hypervisor_hostname | zhaoqin-RHEL-GPFS-tmp1
|
[root@zhaoqin-RHEL-GPFS-tmp nova]# nova show gpfs-vm | grep hostname
| OS-EXT-SRV-ATTR:hypervisor_hostname | zhaoqin-RHEL-GPFS-tmp

Title:
Nova boot fail and raise NoValidHost when use specific aggregate
Status in OpenStack Compute (Nova):
Invalid
Bug description:
1. Set the nova.conf
scheduler_default_filters=AggregateInstanceExtraSpecsFilter,AvailabilityZoneFilter,RamFilter,ComputeFilter
and restart compute, scheduler service
2. Create an aggregate and add a host to it with metadata test_meta=1
3. Modify exist flavor to add the same key:value test_meta=1
4. Boot an instance with this specific flavor and came across
| fault | {u'message': u'NV-67B7376 No valid
host was found. ', u'code': 500, u'details': u' File
"/usr/lib/python2.6/site-packages/nova/scheduler/filter_scheduler.py", line
107, in schedule_run_instance |
