Initialize Vagrant setup
#./vagrant_parallel_provision.sh initialize

* This command will provision a dhcp server and a separate vboxnet adapter.
* This command will provision "httpproxy1" server, that contains dhcp and proxy server.
* Before running the next command , ensure puppet has completed the provision of httpproxy server.

16)
Fix for Connection timeout:

httpproxy1: SSH address: 127.0.0.1:2222
httpproxy1: SSH username: vagrant
httpproxy1: SSH auth method: private key
httpproxy1: Warning: Connection timeout. Retrying...
httpproxy1: Warning: Connection timeout. Retrying...

* Check "/etc/resolv.conf" for correct "nameserver" entry.

17)
#bash vagrant_parallel_provision.sh up >> vagrant.log 2>&1 &

* The above commands , creates a new token for consul.The token and the "vboxnet" for your cluster can be found in the "vagrant_keys".

18)
In order to recreate the  vagrant environment:
#bash vagrant_parallel_provision.sh reset >> vagrant.log 2>&1 &
This will reprovision the entire setup in a new network and a new consul token.    

19)
In order to reprovision the environment by making changes in puppet-mycloud code;
#bash vagrant_parallel_provision.sh provision >> vagrant.log 2>&1 &

20)
In order to destroy the entire system
#bash vagrant_parallel_provision.sh destroy>> vagrant.log 2>&1 &

21)
In order to destroy and bring up a single server in the cluster
#vagrant destroy gcp1
#source vangrant_keys
#vagrant up gcp1

22)
In order to get the status of vagrant servers:
#vagrant status

23)
In order to login to a specific server:
#vagrant ssh gcp1

24)
In order to cleanup the environment:
#bash vagrant_parallel_provision.sh cleanup

under cloud neutron dnsmasq-dhcp debugging

* Here "40:ea:a7:33:7f:0e" is the MAC address of bare-metal node to be provisioned. We have enabled network boot (PXE boot) for the interface which has MAC address "40:ea:a7:33:7f:0e". So UC will get DHCP request from that interface of bare-metal node.

* Here "10.140.15.31" is the IP allocated by dnsmasq-dhcp server running in UC to bare-metal node.

* So we should able to capture following data while running "#nova boot" from UC and confirm that UC getting dhcp request from provisioned node.

ironic how to delete node faster

1)
First set provision-state to deleted

$nova delete [vm-id]
$ironic node-set-provision-state [node-id] deleted

Example:
$ironic node-set-provision-state 2d32d1dd-5363-47d4-a5d6-dc3a1fe7f496 deleted

2)
Then delete the node
$ironic node-delete  [node-id]

* This help us to delete node faster
