Virtual machine management system and method thereof

A management system and method for a virtual machine, in particular, a management system and a method for managing a virtual machine by a management pool.

The use of virtual machines (VMs) with high availability features can effectively reduce the risk of abnormal interruptions to prevent data loss and reduce the loss of data caused by abnormal interruptions.

Due to different business backgrounds, usage scenarios and user scales, etc., the users and levels are different, including server virtualization or desktop virtualization. For desktop virtualization, Microsoft introduced Both Hyper-v Cluster and VMWare's VMontion can achieve high availability of virtual machines. The main key factors are software environment, user personalized software requirements, user personal data size, shared storage device usage, etc.

According to the degree of similarity of the internal software environment of the enterprise, the virtual machine architecture can be divided into independent VHD and differential VHD. The software is similar to each other. The virtual machine image can be organized into a basic image part and a differential image part, usually in order to make The virtual machine has a highly available feature that puts the base image part on the network shared storage device (IP/SAN). The differential image part is configured to roam through the application, and the folder redirection technology puts the user data on the network share. Storage device above.

Create a virtual machine on the main server, and put the virtual machine base image file on the network shared storage device, and configure the user data to roam to the network shared storage device, then join the Hyper-V Cluster for management, when Hyper-V When a host in the cluster is damaged, the virtual machine on the host will automatically Migrate to other hosts in the cluster and restore them on other hosts, because the user data is stored on the network shared storage device, so the user data is not lost, and the virtual machine image files are stored in the network shared storage. On the device, the host just stores the link file and points to the image file, so it is easy to migrate and restore on other hosts.

The above solution is more applicable when the enterprise software environment is relatively complex, and the user's personal data is highly valued or emphasized (such as the office environment or the software development environment), but in some environments, the user data can be relatively simple. It is very small, even allowing the user to delete the security policy after the virtual machine is restarted, and does not allow the user to install or customize the software. In this case, the professional vendor's clustering solution can also satisfy the virtual machine high availability. The characteristics, but not lightweight enough, while purchasing and maintaining expensive shared storage devices will undoubtedly greatly increase the cost of the overall solution.
