Iv. Nova-compute Step 17: After receiving the request from Nova-compute, use resource tracker to declare the occupation of resources required for creating the Virtual Machine. Step 18: Call the neutron API to configure the network. The virtual machine is in the networking state. It should be noted that although this step is to configure the network, it is mainly to prepare the data structure, and the real device is not created. When creating a virtual machine, we specify the private network to w

) Client Authentication is provided by the get method of the rest interface and is usedV1.0As the path. In addition, there are two headers that must provide:X-auth-userAndX-auth-KeyAnd their values are the user name and API access key respectively. Each rest request accessing the openstack Object Storage System must contain a specific header in the HTTP header:X-auth-tokenThe value of this header is the user's access authentication token. The clie

Create an RHEL7 system image for OpenStack Create the RHEL7 system image used by OpenStack, set the image, and install XRDP for remote access. 1. Install the RHEL7.2 client in KVM; 2. Set the NIC to dhcp and onboot = yes so that the virtual machine can automatically obtain the IP address; Vim/etc/sysconfig/network-scripts/ifcfg-eth0 Make sure you can connect to the Internet. 3.

This article describes the process of installing Mitaka Nova in Ubuntu 16.04 under a single point Step 1:root identity into MySQL, create two databases CREATE DATABASE Nova_api; CREATE DATABASE Nova; Step 2: Still in the database, create a Nova user and give permissions, the following command to set a consistent Nova_dbpass value, and then quit MySQL GRANT all privileges on nova_api.* to ' nova ' @ ' localhost ' identified by ' nova_dbpass '; GRANT all privileges the nova_api.* to ' Nova ' @ ' p

OpenStack has become the first choice for many cloud computing vendors to build a private cloud. Many academic institutions also use OpenStack to build a small-scale test environment for students' experiments. Here we will share the process of using OpenStack Virtual Machine to build the Hadoop2.2.0 environment. 1. Prepare the VM Environment

I have recently read about Openstack and have been trying to install it. However, I have referenced a lot of information, which is not satisfactory. Since CentOS has been used for Linux, most Openstack installation is required on Ubuntu. I don't know why. I don't like Ubuntu. Maybe I think it's too fancy, and I always want to update something.

BKJIA exclusive Article] OpenStack is a set of platform software used to manage virtual machines. Instead of a single software, it integrates many components for collaboration. Simply put, for example, there are ten servers. In the case of VMware, we install esx or esxi on each server, and then install a vcenter, in the vcenter management interface, you can add the esx of ten servers to the vcenter by adding domain names or ip addresses. Similarly, Re

Original article: http://www.hengtianyun.com/download-show-id-79.html The resize (upgrade) function of openstack allows us to change the number of CPU cores, memory, and disk size of the Virtual Machine. Of course, the virtual machine can only be upgraded up and cannot be downgraded down. By analyzing the source code, we found that the resize process is actually a cold migration process, and the resize multi-transmits a flavor parameter. The following
