MOS7, MU3, with reduced footprint, virt role install requires LMA nodes

[ZHI BING WANG]

with virt role, I want to define LMA in KVM. So, there is no LMA nodes defined during virt deployment. However, the /etc/fuel/plugins/lma_collector-0.8/puppet/manifests/base.pp still want to find the nodes used for LMA at that time.

2016-07-14 03:31:25 +0000 Puppet (err): $es_nodes[0] is :undef, not a hash or array at /etc/fuel/plugins/lma_collector-0.8/puppet/manifests/base.pp:65 on node node-9.domain.tld

This could be an issue on LMA side, which does not consider the virt role.

To reproduce:

The physical hosts used like this:
1. Fuel
2. a Compute
3. 3 virt hosts

Install Fuel 7, MU 3
Enable reduced footprint
https://docs.mirantis.com/openstack/fuel/fuel-7.0/operations.html#using-the-reduced-footprint-feature

Create an environment, and install LMA 0.8.1, for example:

id | name | version | package_version
---|-----------------------------|---------|----------------
1 | influxdb_grafana | 0.8.1 | 3.0.0
2 | backup | 1.1.0 | 2.0.0
3 | contrail | 3.0.0 | 3.0.0
4 | elasticsearch_kibana | 0.8.1 | 3.0.0
5 | ldap | 1.0.0 | 3.0.0
6 | lma_collector | 0.8.1 | 3.0.0
7 | lma_infrastructure_alerting | 0.8.1 | 3.0.0
8 | openldap | 1.2.0 | 3.0.0
9 | standalone-ceph | 1.0.2 | 3.0.0

create 16 KVM for all the control plane roles.

setup KVMs on virt host like this:
fuel2 node create-vms-conf 9 --conf '{"id":1,"mem":40,"cpu":8}' '{"id":2,"mem":20,"cpu":4}' '{"id":3,"mem":20,"cpu":4}' '{"id":4,"mem":8,"cpu":4}' '{"id":6,"mem":8,"cpu":4}'

Then spawn:
fuel2 env spawn-vms 2 --debug

Then, the virt host deployment will fail with the above error.
