Problems solved by technology

The first method can only be used to create a Power AIX virtual machine, but cannot create a Power Linux virtual machine, and it takes a long time to create a virtual machine
Although the second method can overcome the limitation of the operating system and reduce the time to create a virtual machine, this method has relatively high environmental conditions for software and hardware, especially the need for IBM TPC services and IBM shared storage, which greatly increases the cost

Embodiment Construction

[0018] The specific implementation manners of the present invention will be described in further detail below with reference to the accompanying drawings. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects of the embodiments. It may be apparent, however, to one skilled in the art that one or more aspects of the various embodiments may be practiced with a lesser degree of these specific details. The following description is therefore not to be seen as limiting, but rather the scope of protection is defined by the appended claims.

[0019] The present invention uses a principle similar to IBM SCS-Based to create a Power Linux virtual machine. The virtual disk used by the virtual server in the PowerVM system is actually a logical volume under the VIOS server. The present invention prepares a logical volume installed with Power Linux in advance, modifies a specific...

Abstract

The invention discloses a method for creating a Power virtual server based on storage and copying. The method comprises the following steps of (1) creating the initial virtual server through a System Director, and installing a Power Linux system; (2) modifying a configuration file of the initial virtual server, and deleting the personalized configuration and the information related with the equipment; (3) deleting the initial virtual server through the System Director, but remaining a logic volume corresponding to the initial virtual server in a VIOS (visual internet operating system), and using the logic volume as a template of the new virtual server; (4) copying the logic volume; (5) obtaining the ID (identify) of the copied logic volume; (6) according to the obtained ID of the logic volume, creating the new virtual server; (7) starting the new virtual server, and updating the network configuration.

Description

technical field [0001] The invention relates to PowerVM virtualization technology, and in particular to a method for creating a Power virtual server based on storage duplication. Background technique [0002] PowerVM is a virtualization platform from IBM. PowerVM can maximize the use of server resources, and a Power server can be divided into multiple physical virtual machines. [0003] In a PowerVM environment, there are two methods of creating virtual servers (aka virtual machines). One method is based on the NIM server. NIM (Network Installation Manager) is a service supported on AIX for centralized installation and maintenance of a large number of machines. This method first installs and configures the NIM server, which manages a virtual machine image template library, and installs Or restore a pre-made PowerVM partition. Another method is based on Storage Copy Services (SCS) provided by IBM. This SCS-Based method uses VIOS (Visual IO Server) as the image control node...
