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. View The SELinux status: /Usr

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

There are many ways to install openstack! Manual and automatic deployment; Rdo is the openstack deployment method provided by RedHat. It is very simple, and the latest version of openstack RedHat seems to be the first to appear. It is currently version I! I recorded the installation of version h this time because I used version H; Prerequisites: 1. The operating

The previous section describes the architecture of Cinder, which discusses how Cinder components work together and how they are designed.How cinder-* Sub-services work together from the volume creation processFor Cinder learning, Volume creation is a very good scene, involving each cinder-* sub-service, the following is a flowchart. The customer (which can be an OpenStack end-user or other program) sends a request to the API (CINDER-API): "Create

This note summarizes articles from other places on Microsoft Windows images for OpenStack creation, along with some fir St Hand experience. The whole process of creating Windows $ and Windows images fully usable on OpenStack instances is described there. PrerequisiteTo achieve the creation of a qcow2 Windows image for OpenStack, we need the following ISO images:

It is estimated that the initial use of OpenStack users will be more confusing. What is the initialization password for the image of OpenStack? Different image initialization passwords are not the same, here is a summary.
