Description

A method for automatically upgrading virtual hardware and software of a virtual machine

technical field

The invention relates to the technical field of server virtualization, and specifically provides a method for automatically upgrading virtual hardware and software of a virtual machine.

Background technique

With the continuous development and progress of social economy, the use of computers is becoming more and more extensive. In order to realize functions such as operating speed and storage of multiple computers on one computer, a virtual machine emerges as the times require. Virtualization is a method that essentially refers to the allocation of resources from a logical rather than a physical perspective, and is a method of viewing different physical resources from a single logical perspective. Virtualization is a resource allocation technology from a logical point of view, and it is a logical abstraction of physical reality. For example, currently there is only one computer, but through virtualization technology, it seems to users that there are multiple computers, and each computer has its own physical resources such as CPU, memory, and hard disk. For users, virtualization technology separates software from hardware. Users do not need to consider the specific hardware implementation in the background, but only need to run their own systems and software on the virtual layer environment. The physical platform in the background is independent.

When engaging in the testing of server virtualization products, we will test and verify certain functions from the perspective of users. There are also many virtualization manufacturers such as VMware, Citrix, and Microsoft. Each product has its own product characteristics, but the most basic functions can be realized, but the implementation methods are different. Every time they release a new version, they will consider the maintenance and upgrade of the old version. After all, at different time stages, different users are using their different versions of the product. For example, an old user has used VMware's EXSI5.0 for two years, and found that VMware recently released EXSI7.0. The old user not only wants to update the virtualization platform software, but also wants to update the virtual machine he uses. For example, after installing a batch of virtual machines created based on templates before Windows 7, and now want to upgrade to Windows 10 or to another system version, generally we will upgrade the virtual host and management node used by the user. If the version of the virtual machine is old, you can Then recreate the installation. However, the user has been using this virtual machine for a long time, and various application software have been installed on it. It will take a lot of time to recreate the virtual machine and then install various application software. Therefore, if the version of the host and management nodes can be upgraded, let The virtual machine automatically recognizes the template of the new version, and automatically completes the upgrade of the new version of the virtual machine, so that the user does not need to reinstall the virtual software, thereby saving a lot of time.

Contents of the invention

The technical task of the present invention is to solve the above-mentioned existing problems, and provide a simple operation that enables the virtual machine to automatically scan new versions of hardware and software, so that the virtual machine user can complete the version upgrade and the latest application of the virtual machine according to the scanned prompts. A method for automatically upgrading virtual hardware and software of a virtual machine for synchronizing software data.

The applicable application scenarios of the method are as follows:

(1) The hardware information on the server node where the virtual machine is located has changed, or the virtual machine has been migrated to another host node, and the hardware information of the target host is inconsistent with the hardware information of the original host;

(2) The hardware and software information of the host where the virtual machine is located has not been updated, and the template on which the virtual machine is based has changed, such as several new application software installed;

(3) The version of the server on which the virtual machine runs has been upgraded to a higher version, and the version of the operating system it supports is also upgraded accordingly.

To achieve the above object, the present invention provides the following technical solutions:

A method for automatically upgrading virtual hardware and software of a virtual machine,

(1) Upgrading virtual hardware: Integrate the driver tool software into the shared directory on the server node of the virtualization platform, integrate the drivers of various hardware devices in the driver tool software, and set a regular scan of the new hardware version and scan path for the virtual machine. Automatically give user prompts when a new version of hardware is found;

(2) Upgrading the virtual software: store the new version of the virtual machine operating system and the new template of the virtual machine on the shared storage on the server node of the virtualization platform, and set a regular scan for the new software version and scanning path for the virtual machine. When a new version is found Automatically give user prompts when using the software.

As preferably, when upgrading the virtual hardware, when the hardware on the underlying host node where the virtual machine is located changes, the virtual machine running on the host automatically recognizes the new hardware device and automatically gives a user prompt during regular scanning; when the virtual machine migrates to other hosts On the node, the virtual machine automatically recognizes the hardware device of the new node and automatically gives the user a prompt when scanning regularly.

For the scenario (1) to upgrade the virtual machine hardware: install driver tool software on the virtual machine in advance, such as tool software similar to vmtools. When the hardware information on the server node where the machine is located changes, or the virtual machine is migrated to another host node, the regular scan set by the virtual machine can automatically identify the new hardware device, and give the user a prompt, and the user decides whether to update it. If the user chooses No, the original version of the hardware resources will continue to be used. If there are compatibility and performance loss problems, the user can also give suggestions; if the user chooses to upgrade, the new version of the hardware package can be loaded for the upgrade operation. After the upgrade is completed Restart the virtual machine to synchronize the data on the new version to the virtual machine.

As a preference, when upgrading the virtual software, the new template made by the virtual machine is stored in the shared storage in the form of a file, and the new template and the original template are placed in the same directory. When the template is produced by the same virtual machine, a prompt is automatically given to the user.

For the (2) scenario of upgrading the virtual machine template: the virtual machine created based on the basic image, the basic image can be understood as a template, the template itself is made by the virtual machine, and the original virtual machine that made the template is installed with the new application again The created template is stored under the branch of the original template, so that the virtual machine can recognize the new template when scanning regularly, and automatically give the user a prompt. It is also up to the user to decide whether to update. The process is the same as the scenario (1).

As a preference, when upgrading the virtual software, the pre-installed version of the new version of the operating system is placed on the network file system mounted on the host node. When the virtual machine regularly scans and automatically recognizes the new version of the operating system, a user prompt is automatically given.

For scenario (3) to upgrade the operating system version: put the kernel and installation package of the new version of the upgraded operating system on the PXE server or in the local storage of the virtualization platform server, so that the virtual machine can identify the new version of the operating system when scanning regularly. A user prompt is given after the version, and the user also decides whether to update, the process is the same as scenario (1).

Compared with the prior art, the present invention has the following prominent beneficial effects: the virtual machine can automatically scan new versions of hardware and software through the method, and the virtual machine user can complete the version upgrade and the latest application of the virtual machine according to the scanned prompts. The synchronization of software data breaks the original idea of only needing to upgrade the underlying drivers, which can save the maintenance and operation time of administrators and improve work efficiency.
