Bug 1130192

So, looking at the yaml, I see several spots where both vlxan and gee are listed, these look to me to be the most relevant:

key: ovs_tunnel_types
        role: HA Controller
        puppetclass: quickstack::pacemaker::neutron
        value: ! '["vxlan","gre"]'

and

key: ovs_tunnel_types
        role: Compute (Neutron)
        puppetclass: quickstack::neutron::compute
        value: ! '["vxlan","gre"]'

I see the segmentation param is already set to 'vxlan', so I suspect staypuft just needs to update how they are populating the above two fields, moving there so they can loo at it.

neutron shall not create any tunnels unless there are VXLAN or GRE networks tenant networks.


Leonid, did you create any tenant networks with gre?

That's allowed with the current configuration (mixed GRE & VXLAN). But the tunnels should only come up in it's flavours if you create specific GRE or VXLAN segmentation networks for tenants.

If that's not the case,

One fix could be limiting to only "gre" or only "vxlan" on all the configuratioms when we chose one.

Fresh install, no tenants created yet :

It was a fresh install. no tenants were created.

Leonid,

Do you happen to have any puppet logs from the node available? Is this still reproducible? Limiting ovs_tunnel_types to just the tenant network type chosen by the user may help this, but it may not be sufficient, depending on exactly why the extra tunnel is being created.

PR is: https://github.com/theforeman/staypuft/pull/305

This limits ovs_tunnel_types to the selected tenant type.
