Embodiment Construction
[0024] Such as figure 1 , 2 As shown, the virtual machine image format conversion tool used in the present invention is clonezilla, and the startup CD downloaded from the official clonezilla is clonezilla-live-2.1.1-25-i686-pae.iso. The specific process is as follows:
[0025] 1. Burn clonezilla-live-2.1.1-25-i686-pae.iso (32-bit system) or clonezilla-live-2.1.1-25-amd64.iso (64-bit system) into the virtual The CD-ROM drive of the physical machine mirrored by the computer, boot from the CD; select "Start_Clonezilla to use Regeneration Dragon"; select "device-image hard disk / partition";
[0026] 2. Configure the host to save the backup file, select "ssh_server uses the directory of the SSH server", and save the generated backup file to a certain directory of the host;
[0027] 3. Prepare the host machine. The host machine in this implementation case is a Linux system, and the SSH server has been installed;
[0028] 4. Enter the relevant information of the host SSH server in...

The invention relates to the technical field of cloud computing, in particular to a method for generating virtual machine images from a legacy system. According to the method, a starting disk of a virtual machine image format conversion tool is placed in CD driver equipment of a physical machine where legacy application is located, and then the physical machine is restarted; a BIOS starting item is set after the physical machine is turned on, and the CD driver equipment is started; after the CD driver equipment is started, the disk partition where the legacy application is located is selected, and a path where generated target images are stored is input; a tool reads partitioned data according to blocks, and the partitioned data are compressed and written into target image documents; image generation is successful, the physical machine of the legacy application is restarted, the virtual machine image format conversion tool is taken out of the CD driver to start the disk; the generated image document is restored to the virtualization environment for operation. The method solves the problems that the system migration of legacy application is low in image conversion success rate and low in image conversion efficiency, and a image generating tool depends on detailed operation systems, and the like, and can be used for migrating various versions of legacy application operation systems into virtualization environments.
Description
technical field [0001] The invention relates to the technical field of cloud computing, in particular to a method for generating a virtual machine image from a legacy system. Background technique [0002] Under the general trend of cloud computing development, many legacy applications need to be transferred from physical machines to run on virtual machines. This requires generating a virtual machine image from the operating system of the legacy application together with the application, and then migrating the image to the virtualization environment. The current common method is to install the required virtual machine image format conversion tool in the operating system of the legacy application, select the disk partition where the legacy application is located, use the virtual machine image format conversion tool to generate a target image file, and convert the files in the disk partition Read out one by one, compress and write to the target image file. There are many prob...
