What is C ++/CLI? C ++, of course, refers to the C ++ language invented by Bjarne Stroustrup In the BELL lab. It implements a static object model with optimized speed and size during runtime, however, in addition to heap allocation, it does not support dynamic program modification. It allows infinite access to the underlying device, but it is almost impossible to operate the activity type while the program is running, and cannot operate the underlying
Virtual Machine creation Process:According to the official flow chart, I personally divide the creation steps of the OpenStack cloud host into four phases:1. Keystone Verification Phase2. Nova Service component Exchange3. OpenStack Other Service Exchange4. Perform the creationFirst Stage: Keystone verification

Creating a cloud host in OpenStack first has to be mirrored, while the Glance module provides mirroring service capabilities, including: Image discovery, retrieval, and storage, including: Glance-api and glance-registery two services, respectively, responsible for mirrored storage and
What is OpenStack?
OpenStack provides open source software to build public and private clouds. OpenStack is a community, project, and open source software that helps enterprises run virtual computing or storage cloud. The OpenStackd open-source project is maintained by the community, including OpenStack computing (code
Nova is a compute service that can start a virtual machine instance. These services can be configured on a separate node or on the same node. Most services run on the controller node and run the virtual machine service on a dedicated compute node. This time, we deploy the compute to the control node.4.1 Install Compute Controller services (Installation Compute service)4.1.1 installation of compute required Packages# yum Install Openstack-nova-api

You can set the maximum and minimum values based on the number of network nodes. If you deploy four network nodes but set the maximum value to 2, only two L3 agents will be used for HA routing (one is master and the other is slave ).
Min is used to check the robustness (sanity): If you have two network nodes, one of them is broken, any new route will fail during this time, because you need to start at least min L3 agent to establish ha routing.
