Embodiment Construction
[0078] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0079] figure 1 A flow chart of a method for starting a physical host provided by an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:
[0080] 101. The management node communicating with the physical host starts the physical host through PXE, and enters the first system of the physical host;
[0081] Specifically, PXE (preboot execute environment, pre-boot execution environment) is the latest technology developed by Intel Corporation, including server and client. In this embodiment, the client is a physical host, and the server is a management node. Through PXE In the startup mode, the management node can download the image from the remote server through the ...

The invention relates to booting methods and systems of a physical host. One of the methods comprises the following steps: booting the physical host by a management node in communication connection with the physical host through a PXE (preboot execute environment); exporting a virtual-host mirror image file, which is pre-stored in a memory, by a block-device server to form a first block device; remotely accessing the physical host by the management node, and controlling the physical host to establish communication connection with the first block device; and copying data, which are of the firstblock device and contain the virtual-host mirror image file, to a hard disk of the physical host by the management node, carrying out adaptation modification, and booting the physical host. The method has the advantages that: 1, a cloud-platform user can boot the physical host simply by using the virtual-host mirror image file without the need for preparing two sets of image libraries for the physical host and a virtual host, storage space is saved, and use and maintenance are also facilitated; and 2, each of a booting mirror image and a virtual-host mirror image can be dynamically configuredin deployment.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to a method and system for starting a physical host. Background technique [0002] With the popularization and development of cloud computing technology, more and more applications and services run on virtual hosts created based on virtual host image files. Users can create new virtual host image files for these virtual hosts according to the needs of deployment and maintenance. Virtual hosts can meet the needs of a large part of applications. However, some applications, such as database services, high-performance computing clusters, etc., need to run on physical hosts for performance reasons; , security and other requirements, but also run on the physical host. However, physical hosts and virtual hosts have completely different implementation mechanisms, and they also have relatively large differences in hardware configuration, system configuration, and network configuration. ...
