<p>A memory retaining unit (106) of a virtual machine handling system (10) retains a memory image (IMG) of a first computer (100). An update recording unit (203) records update information (UD) that indicates a partial area of a memory image (IMG1), which is updated when a virtual machine executing unit (202) of a second computer (200) makes the transferred virtual machine (VM) executed. A returning section (160), upon receiving an undo request, makes partial data (PD) indicated by the update information (UD) transmitted from the second computer (200) to the first computer (100). A virtual machine executing unit (102) of the first computer (100) makes the virtual machine (VM) continue processing, using the memory image (IMG) retained at the memory retaining unit (106), and the partial data (PD) received from the second computer (200).</p> |
