Guest machine execution control system for virtual machine system.
摘要
<p>Mask data (5) in a PSW are latched and sent from a host to a guest are subjected to a logical AND operation with latched data (4) taken from an intervention request field of a state descriptor (13) of the guest machine. The resultant logical product (6) is used for setting the PSW of the guest machine and activating an interception to the host. The overhead of an execution controller (3) managing the state transition between guest-host machines is reduced.</p>
