| 摘要 |
The invention relates to a method for assisting the identification of incidents on a virtual machine (VM1) hosted by a host system (10), the virtual machine comprising an operating system (OS1) communicating with a hypervisor (101) of said host system, said hypervisor interfacing between the operating system and hardware resources of the host system, said method comprising the following steps implemented by the hypervisor: - receiving (E3), from the operating system, at least one machine instruction corresponding to an interruption of the operating system, said interruption being consecutive to an event occurring on the virtual machine, - executing (E4) of the instruction by the hypervisor using the hardware resources of the host system and transmitting (E5), to the operating system, a stream of data comprising the result of the execution of the interruption, characterised in that the data stream is duplicated (E5) in a second stream, said second stream being transmitted to the operating system of a second virtual machine (VM1') after a delay with respect of the transmission of the stream to the operating system of the virtual machine, the second virtual machine being distinct from the virtual machine, an incident occurring on the virtual machine only occurring on the second machine after the delay. |
