The OpenStack Kilo version, the 11th version of OpenStack, an open source project, was officially released in April 2015. Now is the time to look at what has changed in this version of neutron and what new key features have been introduced.1. Expand the Neutron development community (scaling the Neutron development community)To better scale the Neutron development community, we have done two main things in

Security groups in OpenStack implement communication between trusted virtual machines, and the same security policy is used for virtual machines that bind to the same security group. The security group is scoped to the virtual machine and more specifically to the port on the virtual machine than to the network. The security group in OpenStack is based on iptables implementation, and because the current open

Keystone Certification Process User uses credentials (Username/password) to Keystone authentication and obtains a temporary token and Generic catalog (global catalog), and temporary tokens are stored in the keystone-client (cache UUID locally) and Keystone-backend. User uses this temporary Token to send to Keystone and obtains a tenants list that the user can
Test classification in OpenStack
Test categories in OpenStack can be divided into the following types:1) unit test (small test/unit tests)
Unit tests are stored in the code library of each component. For example, unit tests of nova are stored in the nova/tests directory.
Unit Tests are mainly aimed at testing the source code and testing the code at the function level.

Chinese garbled characters in OpenStack Databases
The SQL connection of openstack must be configured with UTF-8 to avoid Chinese garbled characters.
SQL _connection = mysql: // nova: xxx @ qa-mysql1: 3306/nova? Charset = 'utf-8'
However, if UTF-8 is not set before, the database cannot be cleared at will. to update a field in the openstack database, you cannot dir

To get a better understanding, let's start with the type of cloud computing. Depending on the type of service provided, cloud computing has the following three landing methods:1. Iaas (infrastructure as a service) from which users can request hardware or virtual hardware, including bare metal or virtual machines, and then install the operating system or other applications on top.2, PaaS (Platform-as-a-service), the user can apply to a installation of the operating system and support the applicat
