MOS 7.0 MU1 kvm+vmware environment fails to deploy with custom hostname for node

[Ihor Stehantsev]

Problem:
nova-compute service configuration file does not get configured by puppet
manifests. Nailgun provides incorrect value in target node field, when
user changes hostname of a compute-vmware node on the Nodes tab.

Expected result:
cluster deploys without errors.

Actual result:
manifests do not configure nova-compute properly, after that vcenter_hooks.py
script is not able to add hypervisors (vSphere clusters in this case) to
availability zone.

Steps to reproduce:
1. Create cluster with vCenter
2. Add 1 controller
3. Add 1 compute-vmware node
4. Configure nova-compute (VCDriver) service on the VMware tab to use that
   node (set "Target node")
5. Switch to the Nodes tab
6. Rename hostname of compute-vmware node (click gear icon cogwheel)
7. Change "Hostname" (click pencil icon) parameter in popup window

Reproducable: 100%

Hi, thank you for your report, but please provide diagnostic snapshot from the failed environment if it is possible.

[Ihor Stehantsev (istegantsev)]

I can not provide a snapshot, as far as it happened on a customer env, and I do not have access to it.

[Andrian Noga (anoga)]

Colleagues,

to fix this bug, we need to get a snapshot.

[Alexander Arzhanov (aarzhanov)]

Possible causes:
1. MOS 7.0 GA OpenStack integration requires a vCenter service account with the following minimum permissions (see point about "VMware vCenter service account"):
http://docs.openstack.org/kilo/config-reference/content/vmware.html
Please check your vCenter account permissions. Most likely, you are missing, at least, "Register extension" permissions.
2. Double check data on VMware tab (vCenter host, vCenter username, vCenter password, vSphere cluster,etc)
3. Check network connectivity to vCenter. Can you ping vCenter IP or vCenter dns name from compute-vmware node?

I raise the Importance to High, because it's customer-found bug and it is very important for Wells Fargo.

    Fix manifest behaviour on hostname change

    Manifest relies on fact that 'target_node' value that is provided by
    Nailgun will always match pattern 'node-[0-9]', but backend provides
    hostname that can be changed by user.
