[Openstack] API endpoint naming in Keystone

2018-04-03 Thread Andrew Bogott 
I just now upgraded my test install (nova, keystone and glance) from 
Liberty to Mitaka.  Immediately after the upgrade, every compute query 
in the openstack client or Horizon started returned a 404.


I resolved this problem by changing all of my nova endpoints in Keystone 
that looked like this:


   http://labtestnet2001.codfw.wmnet:8774/v2/$(tenant_id)s

so that they now look like this:

   http://labtestnet2001.codfw.wmnet:8774/v2

I can't find any online documentation to support this change. Every 
how-to guide includes the $(tenant_id)s component of the endpoint for 
nova, although other services (e.g. glance) seem not to recommend it.  
Can anyone help me understand what's going on here?  Are the docs just 
out of date, or do I have some subtle breakage in my install that this 
is revealing?


Thanks!

-Andrew

[Openstack] [neutron] Integration SDN controller

2018-04-03 Thread Matheus Wagner 
Hi colleagues,

I want to do the Neutron integration (liberation version) with an SDN Ryu
controller. But so far I have not found much that could help me how to do
this. Anyone here already made this integration? Do you know how to
proceed? Please help me :)

[Openstack] [neutron] Advice on replacing (non-openstack) existing IPv6 setup

2018-04-03 Thread Erik Huelsmann 
Hi,

I'm seeking some advice on replacing a libvirt/manual setup with an
openstack/VM based one. Most of the work has been done and seems to work,
however, the existing setup has working IPv6 on the host as well as the
guests -- something that I have failed to achieve so far with the OpenStack
replacement.

My situation is a single host with a /64 subnet assigned. The guests and
the host have been assigned an IP from the available /64 subnet. All
traffic from the host and the guests needs to be routed upstream through
fe80::1.

Everything works as long as I don't set up any IPv6 at all. But when I set
up the external interface (enp4s0) with an IPv6 address (no matter which
one), the linux bridge receives "File exists" errors from RTNETLINK.

Can anyone point me to configuration examples or installation documentation
for the case I'm trying to configure? (Note that I have looked at this
page: https://docs.openstack.org/mitaka/networking-guide/config-ipv6.html
but the fact that it talks a lot about prefix delegation makes it very
confusing, tbh...)

Thanks in advance for any advice you can provide!

[Openstack] [HEAT] order in attributes list

2018-04-03 Thread Volodymyr Litovka 

Hi colleagues,

I have the following HOT configuration of a port:

  n1-wan:
    type: OS::Neutron::Port
    properties:
  fixed_ips:
    - { subnet: e-subnet1, ip_address: 51.x.x.x }
    - { subnet: e-subnet2, ip_address: 25.x.x.x }

when I try to extract these values in template using {get_attr}, then, 
regardless of fixed_ips' order in port definition (either "subnet1, 
subnet2" or "subnet2, subnet1"), the value of { get_attr: [n1-wan, 
fixed_ips] } always give the following result:


output_value:
   - ip_address: 25.x.x.x
      subnet_id: ...
   - ip_address: 51.x.x.x
 subnet_id: ...

and, thus, { get_attr: [n1-wan, fixed_ips, 1, ip_address ] } gives me 
51.x.x.x value.


So, the question is - how the list of fixed_ips is ordered? Is there way 
to know for sure index of entry I'm interested in?


Thank you.
