Hi Mauricio, What happens if instead of the node name you use the node UUID, as returned from; openstack hypervisor list ? On Wed, 3 Feb 2021, 17:46 Mauricio Tavares, <raubvogel@gmail.com> wrote:
Easy peasy question: According to https://docs.openstack.org/nova/rocky/admin/availability-zones.html, I can specify the host I want to use by following the format
--availability-zone ZONE:HOST
So, let's get the hostnames for the compute nodes.
[raub@test-hn ~(keystone_admin)]$ openstack compute service list --service nova-compute
+----+--------------+-----------------------+------+---------+-------+----------------------------+ | ID | Binary | Host | Zone | Status | State | Updated At |
+----+--------------+-----------------------+------+---------+-------+----------------------------+ | 11 | nova-compute | compute02.example.com | nova | enabled | up | 2021-02-03T17:25:53.000000 | | 12 | nova-compute | compute03.example.com | nova | enabled | up | 2021-02-03T17:25:53.000000 | | 13 | nova-compute | compute01.example.com | nova | enabled | up | 2021-02-03T17:25:52.000000 |

I want to use compute01.example.com, which I can resolve to 10.1.1.11. But, when I try to create server with (running as admin):
openstack server create \ --image default_centos_8 \ --flavor m1.small \ --key-name raubkey \ --availability-zone nova:compute01.example.com \ --nic net-id=LONG_BORING-ID \ raub-netest
I get the error message (from openstack server show raub-netest|grep fault):
'message': 'No valid host was found. No such host - host: compute01.example.com node: None '
What am I doing wrong here?
