To Check VM Status

stack@mitakagnocchi:~/devstack$ nova list
+--------------------------------------+-------+--------+------------+-------------+--------------------------------------------------------+
| ID                                   | Name  | Status | Task State | Power State | Networks                                               |

+--------------------------------------+-------+--------+------------+-------------+--------------------------------------------------------+

Adding Floating IP

Get a floating IP first.


stack@mitakagnocchi:~/devstack$ nova floating-ip-create
+--------------------------------------+--------------+-----------+----------+--------+
| Id                                   | IP           | Server Id | Fixed IP | Pool   |

+--------------------------------------+--------------+-----------+----------+--------+

Associate a floating ip.

stack@mitakagnocchi:~/devstack$ nova add-floating-ip --fixed-address 10.0.0.4 lala1 172.16.235.5

To Check floating IP

stack@mitakagnocchi:~/devstack$ nova list

Release Security Group

Check Rules of Default Security Group.

stack@mitakagnocchi:~/devstack$ nova secgroup-list-rules default
+-------------+-----------+---------+----------+--------------+
| IP Protocol | From Port | To Port | IP Range | Source Group |
+-------------+-----------+---------+----------+--------------+

+-------------+-----------+---------+----------+--------------+

Free ICMP.

stack@mitakagnocchi:~/devstack$ nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range  | Source Group |

+-------------+-----------+---------+-----------+--------------+

Free TCP

stack@mitakagnocchi:~/devstack$ nova secgroup-add-rule default tcp 1 65535 0.0.0.0/0
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range  | Source Group |

+-------------+-----------+---------+-----------+--------------+

Connect to VM via Floating IP

Now we can login to VM

stack@mitakagnocchi:~/devstack$ rm ../.ssh/known_hosts
stack@mitakagnocchi:~/devstack$ ssh cirros@172.16.235.5
The authenticity of host '172.16.235.5 (172.16.235.5)' can't be established.
RSA key fingerprint is 7f:ac:8d:c0:48:12:fb:57:68:9d:ec:10:02:55:fb:ce.
Are you sure you want to continue connecting (yes/no)? yes

Furthermore

To Internet

Modify Nameserver, you then can go to internet.
