VScaler: Get HPCoD working with Kolla

• Change/Set some Neutron settings ==

[root@mitaka-head ~] cat /etc/kolla/config/neutron/ml2_conf.ini 
[securitygroup]
firewall_driver = neutron.agent.firewall.NoopFirewallDriver

[agent]
prevent_arp_spoofing = False

[root@mitaka-head ~] kolla-ansible -i vScaler/deploy/multinode reconfigure

• Set the MTU on the Head node VM to 1450. This can be done, either by:
  • Adding the command in the head-init.sh script, which gets executed by cloud-init, during boot time
  • Manually making the change in the head node and then grabbing a new snapshot of the VM

• The head node needs to be pointing to the public heat endpoint, otherwise it can't send the signal to start the compute node provisioning.
  • I did this by setting the internal endpoint to be the same as the public one.
