System and method for virtual machine placement and management in cluster system

A system for placing and managing virtual machines in a cluster node system, the system comprising:

• a virtual machine placement policy manager configured to determine a placement policy of a virtual machine to be generated according to a virtual machine generation request from a user;
• a virtual machine placement manager configured to select a group in which the virtual machine is to be placed according to the determined placement policy and a purpose of generating the virtual machine;
• a global virtual machine group manager configured to manage physical machines and virtual machines operated in the group, and select a subgroup of the group in which the virtual machine is to be placed;
• and
• at least one local virtual machine group manager configured to manage physical machines and virtual machines operated in at least one subgroup of the group,
• wherein the local virtual machine group manager, which manages the selected subgroup among the at least one local virtual machine group manager, generates the virtual machine, selects a physical machine in which the virtual machine is to be placed, and places the virtual machine.
