VMs do not finish booting on first node in two node RDO icehouse installation

I've installed a standard RDO (icehouse) allinone setup. After that I've added additional compute node.

I had the following issue: https://ask.openstack.org/en/question/30090/network-is-slow-on-compute-node-of-two-node-icehouse-neutron-ovsvlan-centos-65-fedora-20-cluster/ (https://ask.openstack.org/en/question...) ; which was resolved as suggested in the link. BUT, for some reason I cannot now launch VMs on the first node (which is the all in one).

I don't remember any configuration changed, but it seems that VMs launching on the first node have an issue with networking or metadata (they can't reach 169.254.169.254), also, for example, the images do get IPs and network seems to work in them, but they don't get ssh keys injected.

Any tips and suggestions are welcome.

Update:

Just checked the following:

  1. Starting a VM (cirros) on the second node happens fast, DHCP request is handled once and fast, metadata contacted fine.
  2. Starting a VM (cirros) on the first node (where controller and network are running) is happening slowly, DHCP request handled twice, metadata is not reached.

So I imagine the issue is network-related config on the first node. But what can it be?

Thanks.

I would suggest you install both nodes at a single run of packstack, rather then add compute node to AIO node. View for instance

Disable checksums offloading on Compute cannot affect Controller. But second packstack run to add Compute Node seems not to change properly AIO host configuration.

I've tried to rerun the install with the answerfile over the existing installation. It took few times to configure the answerfile properly to have it run without errors.

It didn't help. The problem is still the same.

I believe you need two boxes with fresh OS install done.

Just did fresh install with answerfile. Finished without problems. Now the problem is on both nodes.
