Virtual system control method and apparatus

A computer-readable, non-transitory storage medium storing a program for causing a computer to execute a virtual system control process, the virtual system control process comprising:

• receiving a deployment request for requesting to deploy an operational system of a specific virtual system in a physical server pool in which operational and test virtual systems can be deployed;
• first activating plural types of virtual machines necessary for said operational system of said specific virtual system in said physical server pool by using first server configuration data in configuration information for said operational system of said specific virtual system and a first virtual machine image for said operational system of said specific virtual system;
• second activating plural types of virtual machines to be added to said operational system of said specific virtual system in said physical server pool by using second server configuration data in configuration change information representing configuration information concerning difference between said operational system and a specific type of said test system to be tested immediately before said operational system works and a second virtual machine image for the virtual machine relating to said difference, said plural types of virtual machines to be added to said operational system play additional roles to roles which said plural types of virtual machines necessary for said operational system play;
• identifying a first link that is included in a network of said operational system and is not included in a network of said specific type of said test system, and a second link that is not included in said network of said operational system and is included in said network of said specific type of said test system, by using said configuration change information;
• setting said first link to be deleted from said operational system and said second link to be added to said operational system;
• carrying out a specific test for said specific type of said test system to said specific virtual system;
• upon detecting that there is no problem in said specific test, stopping the activated virtual machines according to said second server configuration data included in said configuration change information, and returning said physical servers relating to the stopped virtual machines to said physical server pool;
• and
• setting said second link to be deleted from said specific type of said test system and said first link to be added to said specific type of said test system.

A virtual system control apparatus, comprising:

• a configuration information storage device to store configuration information for an operational system of a virtual system;
• a first virtual machine image storage device to store first virtual machine images for said operational system of said virtual system;
• a configuration change information storage device to store configuration change information that represents configuration information concerning difference between said operational system of said virtual system and plural types of test systems;
• a second virtual machine image storage device to store second virtual machine images for virtual machines relating to said difference;
• and
• a controller, and
• wherein said controller activates plural types of virtual machines necessary for an operational system of a specific virtual system in a physical server pool in which said operational and test virtual systems can be deployed, by using first server configuration data in said configuration information identified from said configuration information storage device for said operational system of said specific virtual system and said first virtual machine image identified from said first virtual machine image storage device for said operational system of said specific virtual system,
• said controller activates plural types of virtual machines to be added to said operational system of said specific virtual system in said physical server pool by using second server configuration data in said configuration change information that represents the configuration information concerning difference between said operational system and a specific type of said test system to be tested immediately before said operational system works and is identified from said configuration change information storage device, and said second virtual machine image identified from said second virtual machine image storage device for the virtual machine relating to said difference between said operational system and said specific type of said test system, said plural types of virtual machines to be added to said operational system play additional roles to roles which said plural types of virtual machines necessary for said operational system play,
• said controller identifies a first link that is included in a network of said operational system and is not included in a network of said specific type of said test system, and a second link that is not included in said network of said operational system and is included in said network of said specific type of said test system, by using said configuration change information;
• said controller sets said first link to be deleted from said operational system and said second link to be added to said operational system;
• said controller carries out a specific test for said specific type of said test system to said specific virtual system,
• upon detecting that there is no problem in said specific test, said controller stops the activated virtual machines according to said second server configuration data included in the identified configuration change information, and returns said physical servers relating to the stopped virtual machines to said physical server pool, and
• said controller sets said second link to be deleted from said specific type of said test system and said first link to be added to said specific type of said test system.
