[Bug 2012391] [NEW] FQDN inside guest VM is not the same as dns_assignment on network port

 

Public bug reported:

Hi,

Here is what we're trying to achieve :
- create a tenant associated to a provider network (vlan based, no FIP)
- create a dns zone associated to this tenant with Designate (basically, <tenant>.<basedomain>)
- create instances within this tenant which will have recordsets created automatically in the DNS zone in the form <instance>.<tenant>.<basedomain>
- the FQDN inside the VM instance should be what is set in the DNS zone associated to the tenant (so <instance>.<tenant>.<basedomain>)

We're running Charmed Openstack on the yoga/stable channel on Ubuntu 20.04.
We're also using OVN.

Basically, everything that I explained is working and you'll see in the example below that even the instance's network port has the good dns_assignment attribute value with a fqdn in the form <instance>.<tenant>.<basedomain> *but* inside the guest instance, there is no way to get the proper FQDN, neither from "hostname/hostnamectl" nor from the Openstack metadata.
We're always getting the <instance>.<basedomain> formed FQDN.
We don't even see any reference to it inside the metadata, the closest we get is the project_id but not the name.


Here are all the informations I could gathered to describe our issue :

Title:
  FQDN inside guest VM is not the same as dns_assignment on network port

Status in neutron:
  New

Bug description:
  Hi,

  Here is what we're trying to achieve :
  - create a tenant associated to a provider network (vlan based, no FIP)
  - create a dns zone associated to this tenant with Designate (basically, <tenant>.<basedomain>)
  - create instances within this tenant which will have recordsets created automatically in the DNS zone in the form <instance>.<tenant>.<basedomain>
  - the FQDN inside the VM instance should be what is set in the DNS zone associated to the tenant (so <instance>.<tenant>.<basedomain>)

  We're running Charmed Openstack on the yoga/stable channel on Ubuntu 20.04.
  We're also using OVN.

  Basically, everything that I explained is working and you'll see in the example below that even the instance's network port has the good dns_assignment attribute value with a fqdn in the form <instance>.<tenant>.<basedomain> *but* inside the guest instance, there is no way to get the proper FQDN, neither from "hostname/hostnamectl" nor from the Openstack metadata.
  We're always getting the <instance>.<basedomain> formed FQDN.
  We don't even see any reference to it inside the metadata, the closest we get is the project_id but not the name.

  
  Here are all the informations I could gathered to describe our issue :
