PROBLEM TO BE SOLVED: To attain a virtual system-context in a number of virtual partitions by use of small hardware. SOLUTION: The partition-context control device 10 comprises a partition 11, a virtual processor 12, an IO device 13, a virtual context 14 to be referred to for determining a destination of command, which is provided for each partition, one or more cache entries 15 which retain a copy of the virtual context and a partition number the virtual context belongs to, a comparison part 16 which refers to, when a command is issued, the partition number of the command and comparing it with the partition numbers of the cache entries; and a destination determination part 17 which determines the destination of the command, when the partition number of the command is matched with the partition number of any one of the cache entries, by use of the copy of the virtual context retained by the cache entry concerned.
