VIRTUAL MACHINE CONTROL DEVICE FOR CONTROLLING A CLOUD COMPUTING SERVER SYSTEM IN A VIRTUALIZATION BASED CLOUD COMPUTING SERVER SYSTEM AND A METHOD THEREOF

摘要

PURPOSE: A VM(Virtual Machine) control device and a method thereof are provided to prevent damage to the consistency of a file system in a VM when a problem is generated between a hypervisor and a storage unit.;CONSTITUTION: A monitoring unit(150) continuously monitors the availability of virtual storage units by using a storage interface(140) which provides an interface which connects the virtual storage units assigned to VMs(170). A control unit(160) detects the virtual storage unit which is unable to provide a service from the VMs according to a monitoring result. The control unit temporarily stops a process which does not return computing resources used in the VM corresponding to the detected virtual storage unit.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Storage; (120) Hypervisor; (140) Storage interface; (150) Monitoring unit; (160) Control unit
