MEANS OF FUNCTIONAL VIRTUALIZATION FOR LOCKING THE TEAM FUNCTION OF THE MULTIFUNCTIONAL TEAM OF THE VIRTUAL PROCESS

摘要

1. A method implemented in a computer for blocking certain functions for execution by a command from being executed by a logical processor executing a virtual machine, the method comprises: setting (1251) the value of command blocking (1008) for a virtual machine; reading (1252) of a command (1101) by the specified logical processor for execution by a logical processor, the command containing the operation code and determining the function code (1102) from the set of function codes, the function code being used to select the function to be executed by the command, is supported by one or more physical processors; determining (1253) the value of the blocking instructions of the virtual machine; depending on the value of the blocking instructions allowing (1007, 1255) the execution of a command having a function code, the execution of a read command by a logical processor; and depending on the value of the command block that does not allow (1006, 1256) the execution of a command having a function code, the blocking of the execution of a read command and the raising of a program exception event. The method according to claim 1, further comprising: a command blocking value (1008), which was determined for the virtual machine to block the execution of functions for execution by the command, the specified setting of the command blocking value depending on the inclusion of the virtual machine for using the physical processor; installation (1351) a different command lock value defined for another virtual machine running on a different logical processor, the specified setting of a different command lock value depending on the inclusion another virtual machine to use a physical processor;
