Exception handling method, apparatus and system in virtual operating environment

The present application relates to the technical field of industrial Internet operating systems, and particularly, to an exception handling method, apparatus and system in a virtual operating environment, which are used for solving the problem that Guest OS that is operated in a virtual environment has poor robustness. The exception handling method in a virtual operating environment provided in the embodiment of the present invention comprises: monitoring an exception that is generated by Guest OS operated on a virtual machine; and if it is determined according to acquired context information of the exception that the exception is generated due to an out-of-limit operation performed by Guest OS on a kernel code whose operation permission is limited in the virtual machine, rejecting the out-of-limit operation performed on the kernel code by Guest OS, wherein, for a key kernel code in the virtual machine, the operation permission of Guest OS for the kernel code can be extended, that is, one more layer of securi
