摘要： Provided is a failover method for a cluster system for realizing smooth failover of the guest OS's, even when there are many guest OS's, while reducing consumption of computer resources of a server. Smooth failover is realized by preventing competition during failover even when the number of guest OS's is increased. In a cluster configuration in which a slave/master cluster program is operated in a guest OS/host OS, the master cluster program (510) collects and transmits heartbeats of the slave cluster program, thereby realizing failure monitoring through the certain amount of heartbeats without depending on the number of guest OS's. Further, when the master cluster program monitors failures of the slave cluster program of its own computer to find a normal operation of the guest OS, the amount of communication through heartbeats is reduced by eliminating the necessity of communication to a standby system slave cluster program.

摘要： Even when a large number of guest OSs exist, a failover method meeting high availability needed by the guest OSs is provided for the each guest OS. In the event of a physical or logical change of a system, or change of operation states, a smooth failover method can be realized by preventing the consumption of resource amounts due to excessive failover methods, and the occurrence of systemdown due to an inadequate failover method. In a server virtualization environment, in a cluster configuration having a failover method due to hot standby and cold standby, by selecting a failover method meeting high availability requirements specifying performance during failover of applications on the guest OSs, a suitable cluster configuration is realized. Failure monitoring is realized by quantitative heartbeat.

摘要： A method is provided which eliminates redundancy from the shadow PT operation performed by the virtual machine monitor (VMM) when the guest operating system running on a virtual machine updates a guest page table (PT) address. The VMM associates a plurality of shadow PTs with guest PTs and allocates their relation in memory. When it detects the update of a guest PT address, the VMM searches for a shadow PT corresponding to the updated guest PT. If the associated shadow PT exists, the VMM omits rewriting the shadow PT and registers the address of the shadow PT with the central processing unit (CPU). If the associated shadow PT does not exist, the VMM allocates a memory, creates a shadow PT, registers an address of the created shadow PT with the CPU, and records a relationship between the updated guest PT and the generated shadow PT.

摘要： The program attains compatibility of suppression of an overhead accompanying page exception handling in the case of operating a program whose amount of memory use is large on a virtual machine and suppression of the overhead accompanying page exception handling in the case of operating a first OS that has a function of making another OS run on a virtual machine. A VMM creates a shadow PT (Page Table) for prohibiting reading-writing of privileged memory that requires emulation of reading/writing by using a RSV-bit, and registers the shadow PT and the second PT that a second OS operating on the first OS has in an x86 compatible CPU equipped with page exception detecting function using two PT's. When a page exception occurs, the VMM refers to cause code of the page exception and, when a P field of the cause code is 0, determines immediately that emulation is unnecessary.
