step 3, entering an openstack system, creating a blank volume as a system disk of the virtual machine, and setting the starting mode of the volume to be startable, wherein the volume name is as follows: CentOS _ volume, create command as follows:
$openstack volume create\--size 8--availability-zone nova–bootabletrue CentOS_volume
step 4, closing the virtual machine power supply created in the step 2, preparing for mounting the volume, executing the following command, using the instance ID of the virtual machine, and checking the instance ID in the openstack virtual machine details:
$ openstack server stop $ instance _ ID (created instance ID)
Step 5, mounting the volume created in the step 3 on a virtual machine to be used as a system disk, then starting a power supply of the virtual machine, and executing the following commands:
$ openstack server add volume instance _ ID $ volume _ ID $ -device/dev/vdb
$ openstack server start $ instance _ ID (created instance ID)
And 6, after the virtual machine is started, entering a console, installing and configuring an operating system of the virtual machine according to use requirements, wherein detailed description is omitted, the steps of installing the operating system are not different, corresponding parameters can be configured according to the use of the template created according to needs, and software needing to be preset is installed.
And 7, after the operating system is installed, firstly closing the power supply of the virtual machine, then separating the volume mounted on the virtual machine in the step 5, and using the volume to create a template, wherein the commands of closing the power supply and unloading the volume are as follows:
$ openstack server stop $ instance _ ID (created instance ID)
$ nova volume-detail < instanceId > (instance ID) < volume ID > (volume ID)
And 8, uploading the volume separated in the step 7 into a mirror image, designating the mirror image name $ image _ name as a template for use, and executing the following commands:
$cinder upload-to-image--disk-format$disk-format$volume_id$image_name

On the other hand, the Windows system template is made slightly different. Firstly, the current openstack environment is required to be normally available in function, and nova, circular, and glance components are deployed.
Step 1, uploading the Windows mirror image to the openstack environment, taking win7 as an example, and specifying parameters such as the name of the mirror image.
Step 2, because the Windows system does not recognize the virtio disk, a virtio drive needs to be installed for the Windows virtual machine, and metadata 'hw _ set _ cd rom' needs to be added when the browser is created at this time: enter hw _ set _ cdrom and virtio mirror paths in the custom fields (virtio mirror to be put into the corresponding directories in nova _ libvirt and nova _ computer containers), for example: /home/ICS-VirtiO-0.81.iso (the mirror image is to be put under/home of nova _ libvirt and nova _ computer containers)
And 3, creating instance by using the navigator, and selecting the win7 iso image uploaded in the first step.
