Open Stack

Assuming that you are running juno, the starting/booting of vm's has been moved from the scheduler to conductor.  This move has resulted in any error booting a vm returning a no valid host found error.  This was a regressions that I understand should be working on getting fixed.

That said your errors regarding vif plugging are most likely the reason why you can't boot a vm.  Can you provide the output for your public network?  Assuming that the public network is configured as shared *AND* you have ml2 plugin configured on your compute nodes to be able to connect to that network (IE bridge mappings and the like) neutron will happily plug your vm into the "public network" where  normally your L3 routers are taking ip's.  I assume that physnet2 is your private network and physnet1 is suppose to be the public network?

What do the vif plugging errors say?

Subject: Re: [Openstack-operators] [Neutron][Nova] No Valid Host when booting new VM with Public IP

What I'm trying to do is force OpenStack to do something it normally doesn't do for the sake of learning and experimentation. I.e. bind a public network to a VM so it can be accessed outside the cloud when floating IP's are normally required. I know there are namespace issues at play which may prevent this from working, just trying to scope the boundaries of what I can and cannot do really.

Hi Adam

For external network you should use floating ips to access externally to your instances if I understood correctly.

Got a strange error and I'm really hoping to get some help with it since it has be scratching my head.

When I create a VM within Horizon and select the PRIVATE network, it boots up great.
When I attempt to create a VM within Horizon and include the PUBLIC network (either by itself or with the private network), it fails with a "No valid host found" error.

I looked at the nova-api and the nova-scheduler logs on the controller and the most I've found are errors/warnings binding VIF's but I'm not 100% certain it's the root cause although I believe it's related.

I didn't find any WARNINGS or ERRORS in the compute or network node.

Setup:

  *   1 physical host running 4 KVM domains/guests
     *   1x Controller
     *   1x Networ
     *   1x Volume
     *   1x Compute

Controller Node:
nova.conf (http://pastebin.com/q3e9cntH)

  *   neutron.conf (http://pastebin.com/ukEVzBbN)
  *   ml2_conf.ini (http://pastebin.com/w10jBGZC)
  *   nova-api.log (http://pastebin.com/My99Mg2z)
  *   nova-scheduler (http://pastebin.com/Nb75Z6yH)
  *   neutron-server.log (http://pastebin.com/EQVQPVDF)

Network Node:

  *   l3_agent.ini (http://pastebin.com/DBaD1F5x)
  *   neutron.conf (http://pastebin.com/Bb3qkNi7)
  *   ml2_conf.ini (http://pastebin.com/xEC1Bs9L)

Compute Node:

  *   nova.conf (http://pastebin.com/K6SiE9Pw)
  *   nova-compute.conf (http://pastebin.com/9Mz30b4v)
  *   neutron.conf (http://pastebin.com/Le4wYRr4)
  *   ml2_conf.ini (http://pastebin.com/nnyhC8mV)

Back-end:
Physical switch

Any thoughts on what could be causing this?
