摘要： A virtual machine system that restricts use of confidential information only to the case where an authentication has resulted in success. The virtual machine system includes first virtual machine, second virtual machine, and hypervisor. The first virtual machine includes: storage unit storing confidential information; and authentication unit configured to perform authentication and notify the hypervisor of result of the authentication. The second virtual machine uses virtual device that is virtualized storage device. When having received authentication result indicating authentication success from the authentication unit, the hypervisor enables the second virtual machine to access, as substance of the virtual device, storage area storing the confidential information, and when not having received the authentication result indicating the authentication success from the authentication unit, the hypervisor disables the second virtual machine from accessing the storage area storing the confidential information.

摘要： When a process judging unit 109 judges that a target process is a protected process 101, a key judging unit 111 judges whether a target key that is a key generated by a key generating unit 108 is a first key or a second key. When the key judging unit 111 judges that the target key is the first key, a VM communication managing unit 112 notifies the target process of a memory ID of a protected memory region 121 corresponding to the first key. When the process judging unit 109 judges that the target process is an unprotected process, a key transforming unit 110 transforms the target key from the first key to the second key based on the key transformation rule. An HV communication managing unit 105 notifies the target process of a memory ID of an unprotected memory region 122 corresponding to the second key.

摘要： The present invention relates to a virtual machine system that includes a plurality of processors and executes a plurality of virtual machines in parallel with use of the plurality of processors. An aim thereof is to suppress power consumption without sacrificing the performance of the virtual machine system. When there are at least two processors that do not have any virtual machines allocated thereto, one of the at least two processors is supplied with power so as to be placed in a standby state, and a remaining one or more of the at least two processors are not supplied with power.

摘要： An access monitoring section (11) obtains access information including an address conforming to an address stored in a monitoring address setting section (10) from an access signal output from a CPU (1) to a peripheral device (3). An access judging section (13) compares the access information received from the access monitoring section (11) and the last access information stored in an access storing section (12), and stores the obtained access information in the access storing section (12) and requests the transmission of an exception generation notification to an exception generating section (14) when the received access information is different from the last access information while excluding the last access information stored in the access storing section (12) from access information to be compared when the received access information is the same as the last access information. By this construction, throughput can be reduced at the time of emulation and the peripheral device can be efficiently emulated.

摘要： The interrupt level storing unit (16) stores one or more interrupt levels indicating the priority of a generated interrupt and stores the interrupt level having the highest priority among the stored interrupt levels as a second interrupt mask level. The second interrupt type determination unit (13) sets an interrupt level corresponding to the interrupt type of a newly generated interrupt. The priority determination unit (14) notifies the interrupt to the virtual machine control unit (20) when the interrupt level of the newly generated interrupt is higher than the stored second interrupt mask level. As a result, the priority of the virtual machine can be determined according to the task priority and the switching of virtual machines can be adequately controlled even if the virtual machines cannot notify the task priority.
