Term interpretation:

VOI (Virtual OS Infrastructure), virtual operating system architecture.

The VOI is a framework for centralized storage and distributed operation, has no any hardware virtualization layer, and is similar to a working mode of 'diskless workstation era', and the mode is to store system data at a server end and run a desktop on a client terminal. After the client terminal is started, the operating system and the application are loaded to the local cache from the server side, and the normal use can be realized.

Example 1

As shown in fig. 1, the present embodiment provides a method for implementing a mirror operation based on a VOI, including:

The present embodiment is described in detail below:

1. firstly, a network guiding system is manufactured, and a client downloads and operates under network guiding.

The size of the network guidance system is reduced as much as possible in order to shorten the network guidance time.

(1) Manufactured in the centOS7 system, the install package virt-p2v-maker was commanded using yum.

(2) Making a Kickstart document

The Kickstart is an installation mode in a red cap release, and describes various parameters and installed software of the Linux system in a configuration file mode.

Executing virt-p2v-make-kickstart command generates p2v.ks file.

(3) Production of LiveCD

Based on the p2v.ks file, executing the livecd-creator command generates a livecd-p2v.iso file.

(4) And (5) manually cutting the ISO file generated in the last step, and reducing the size of the file.

The method comprises the following steps: and (3) mounting an ISO file, decompressing a squarhfs file system in the ISO file, deleting unnecessary software packages, helping documents and the like according to the requirement, and then reproducing the ISO file.

The network guiding system is stored on the server as a complete operating system in the form of an image file, and the image file is only hundreds of megabytes in size and corresponds to the ISO file. After the terminal is started, the guiding equipment can be selected, and if the local hard disk is selected for guiding, an operating system installed on the local hard disk is started. If the network guidance is selected, the packaged network guidance system is temporarily downloaded from the server through the network, and the downloaded operating system is guided, and the operating system is integrally loaded into the memory to run.

2. And writing a VOI management interface in the network guidance system, and starting up and running when the client network is guided.

The host-p 2v.iso is provided with a VOI management interface running when being started, and is used for converting an operating system in a hard disk to generate an image file in qcow2 or raw format.

The VOI management interface of the VOI management interface is single in function and crude in interface. The invention writes the VOI management interface of the user, and replaces the self-contained interface in the ISO according to the cutting steps.

The whole is divided into a left part and a right part, the left side panel displays the local system information of the terminal, and the right side panel displays the template information of the server.

The overall flow includes image upload, template download and client-side boot local system image.

Mirror image uploading: and installing a Windows10 system in the terminal, installing an agent program, and shutting down. And starting up to select network guidance, and selecting uploading mirror images on the left side panel of the VOI management interface.

Downloading a template: the server creates a template based on the uploaded system image, defines template attributes (e.g. whether to restore) and client network guidance, and clicks the download template on the right panel of the VOI management interface.

The client directs the local system image: and after the client downloads the template, shutting down. And starting up to select a local hard disk to guide the downloaded local system mirror image.

The VOI management interface program is stored in the image file as a part of the network guidance system, and stored in the server in advance. When the terminal selects network guiding, the network guiding mirror image is downloaded, and the downloaded operation system is guided, at the moment, the VOI management interface program automatically operates.

3. Key point in mirror image uploading process

The Virt-p2v is an open source migration tool of Red Hat, which is used for converting an operating system of a physical machine into a virtual machine image and only supports two image formats of qcow2 and raw.

The client side guides the local system image to require the system image file to be in a VHD format, and if the virt-p2v result qcow2/raw file is converted into the VHD format, the whole time consumption of image uploading is greatly prolonged.

The invention backs up and reforms the qemu-img program called when the server executes p2v operation, and directly adjusts the qemu-img program to a VHD format during mirror image conversion, thereby achieving one-step operation.

4. Client-side boot local system image

The invention utilizes open source engineering Ventoy boot image files. And writing a custom starting menu, customizing the file name of the guiding menu, directly displaying the custom starting menu when the hard disk is guided, and selecting and guiding a specific system mirror image.

5. Key point of realizing template restoration

When the server creates the template, three snapshots are created for the system image template by using open source engineering vhd-uteil-cover, which are respectively named as A, B, C, wherein A is taken as a basic snapshot and is kept unchanged.

After the snapshot B is booted, an agent program in the Windows system copies the basic snapshot to cover the C, and rewrites the boot record to use the C boot.

After the snapshot C is booted, an agent program in the Windows system copies the basic snapshot overlay B, and rewrites the boot record to use the boot B.

Thus, the two snapshots are switched back and forth, and the purpose of system mirror image restoration is realized.

6. Agent profile

The agent program is installed in the Windows10 system and automatically executed as a system service boot.

Before the system image is produced, an agent program needs to be installed first, a Windows registry is set, and VHDs are forbidden to automatically expand.

When the client guides the local system mirror image, the client can not automatically expand to the maximum capacity of the client, and the hard disk space is saved.

In addition, the Windows sleep needs to be turned off, otherwise the p2v procedure fails.

After the client guides the local system mirror image, the agent program in the client cooperates to realize the system restoration.

In the VOI scene, the client can download a plurality of template images, and select one of the template images to start according to the requirement, so as to operate different application environments.

Such as: the template image 1 is preloaded with video editing software, and after the template image 1 is started, the user obtains an operating system containing the video editing software.

Such as: if the 3D design software is preloaded into the template image 2, after the template image 2 is started, the user obtains an operating system containing the 3D design software.

In the VOI scene, the system operates as a conventional operating system, directly operates on a physical machine, and can be operated conventionally, such as daily office work, surfing the Internet, sending and receiving mails, playing video music and the like.

In the VOI scene, an operating system is installed in a terminal, required application programs are preloaded, then a template is manufactured based on the existing operating system of the terminal, and the template is uploaded to a server.

And the other terminals download the template according to the requirement and then perform local operation to obtain the operation environment identical to the template terminal.

The VOI is suitable for, but not limited to, the education industry, different subjects make different templates, and teaching management is facilitated.

The present invention supports selecting a boot from a set of VHD images; the original ecology of the operating system kernel or the component in the image file is maintained without modification; template mirroring based on existing operating systems is supported.
