The OpenStack Mirroring Service (glance) allows users to discover, register, and recover virtual machine images. Glance provides the rest API to query the metadata of virtual machine images and to obtain mirroring. With glance, virtual machine images can be stored on a variety of storage, such as simple file storage or object storage (such as the Swift Project in OpenStack).One, the

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 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;
