[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0038] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.
[0039] In a first aspect, an embodiment of the present application provides a virtual machine manager health management method.
[0040] Reference Figure 1 , Figure 1 This is a flowchart of the first embodiment of the virtual machine manager health management method of the present application. The virtual machine manager health management method includes:
[0041] S100, when the virtual machine manager runs the virtualization function, determining whether there is an abnormality in the running state of the virtualization function;
[0042] S200, if there is an abnormality in the running state of the virtualization function, restart the virtual machine manager; if there is no abnormality in the running state of the virtualization function, allow or control the virtual machine manager to start the secure virtual machine operation;
[0043] S300, when the secure virtual machine is started and running, determining whether there is an abnormality in the running state of the secure virtual machine;
[0044] S400: If there is an abnormality in the running state of the secure virtual machine, the secure virtual machine is restarted first, and whether to restart the virtual machine manager is determined based on whether there is an abnormality in the running state of the secure virtual machine after the restart.
[0045] In this embodiment, specifically, the judgment results of the running state of the virtualization function and the running state of the security virtual machine include the judgment results in three aspects: alive, deadline and logic. Furthermore, by running the virtualization function in the virtual machine manager to enable the running of other virtual machines, it is first judged whether the virtualization function has an abnormality, and the virtual machine manager is restarted in time when an abnormality exists, so that it can be re-run and judged, and when it does not have an abnormality, the security virtual machine is restarted to run, and at the same time, the running security virtual machine can be further detected for abnormalities, and the security virtual machine will be restarted first when it is abnormal, and it is judged whether to restart the virtual machine manager based on whether there is an abnormality in the running state of the security virtual machine after the restart.
[0046] Ultimately, it is possible to restart at different levels when different functions are running, allowing modules such as secure virtual machines and virtual machine managers to run in a secure scenario more quickly and effectively.
[0047] Further, in one embodiment, in step S400, if there is an abnormality in the running state of the secure virtual machine, the secure virtual machine is restarted first, and whether to restart the virtual machine manager is determined based on whether there is an abnormality in the running state of the secure virtual machine after the restart, specifically including the following steps:
[0048] S410. If the running state of the secure virtual machine is abnormal, update the number of consecutive abnormalities of the secure virtual machine recorded;
[0049] S420, determining whether the number of consecutive abnormalities is greater than one;
[0050] S430, restarting the secure virtual machine when the number of consecutive exceptions is no more than one;
[0051] S440: When the number of consecutive exceptions is greater than one, restart the virtual machine manager and reset the number of consecutive exceptions.
[0052] Specifically, when an abnormality is detected after the security virtual machine is started and run, it will be judged whether the abnormality is detected after the last startup to determine whether the abnormality exists for two consecutive times when the security virtual machine is started and run. If not, the security virtual machine will be restarted first to reset the possible occasional conditions of the security virtual machine itself, so as to restore the operation of the security virtual machine as soon as possible. If the abnormality exists for two consecutive times when the security virtual machine is started and run, the possibility of occasional conditions of the security virtual machine is greatly reduced. At this time, the operating platform of the security virtual machine, that is, the virtual machine manager, will be further restarted to enable all related programs to be restarted as a whole, so as to maximize the security of the next operation of the virtual machine manager and the security virtual machine.
[0053] After restarting the virtual machine manager, if the secure virtual machine is running and anomalies are still detected, different advanced practices can be adopted in different embodiments, such as outputting an alarm signal to remind technicians of equipment failure, locking the operation of the virtual machine manager or the secure virtual machine, etc. This application does not limit this.
[0054] Furthermore, in one embodiment, the process of determining whether there is an abnormality in the running state of the virtualization function and the process of detecting whether there is an abnormality in the running state of the secure virtual machine are both implemented by a first detection module built into the virtual machine manager.
[0055] In this embodiment, a first detection module arranged in the virtual machine manager is utilized to realize response preparation at the first time the virtual machine manager is started, and the running status of the virtual machine manager can be detected at the first time after the virtual machine manager runs its virtualization function and the virtual machine manager runs the security virtualizer, thereby ensuring that the virtualization function of the virtual machine manager and the security virtualizer that the first detection module is responsible for can run smoothly in a secure environment.
[0056] Since the first detection module is needed to ensure that the virtual machine manager and the secure virtual machine run in a secure environment, it is critical that the first detection module functions normally. Therefore, further, in one embodiment, the step S100, when the virtual machine manager runs the virtualization function, before determining whether the running state of the virtualization function is abnormal, includes the following steps:
[0057] S010, after the virtual machine manager is started, determining whether there is an abnormality in the running state of the first detection module;
[0058] S020: If the running state of the first detection module is abnormal, restart the virtual machine manager or restart the running system of the virtual machine manager.
[0059] Specifically, in this embodiment, a second detection module provided outside the operating system of the virtual machine manager determines whether the operating state of the first detection module is abnormal. The second detection module independent of the virtual machine manager is used to detect the first detection module, so that the second detection module is not affected by the abnormality of the virtual machine manager and its operating system, which may cause the second detection module to be unable to detect the first detection module.
[0060] Such a setting ensures that the relevant technical personnel can be informed in time when the first detection module fails through the second detection module, thereby avoiding the operation of the virtual machine manager and the secure virtual machine when the first detection module fails, further improving the security of the method of the present application when in use.
[0061] Further, in some embodiments, the step S020, if the running state of the first detection module is abnormal, restarting the virtual machine manager or restarting the running system of the virtual machine manager, includes the following steps:
[0062] S021. If the number of consecutive abnormalities in the running state of the first detection module is one, restart the virtual machine manager; if the number of consecutive abnormalities in the running state of the first detection module exceeds one, restart the running system of the virtual machine manager.
[0063] Such an arrangement enables different restart strategies to be adopted when facing different consecutive abnormal times of the first detection module. Specifically, when the operation abnormality of the first detection module occurs only once, the device can be restarted in a small range, that is, the virtual machine manager running the first detection module can be restarted, so as to restore the normal operation of the first detection module as soon as possible or determine the fault degree of the first detection module; when the first detection module has two operation abnormalities, it means that the first restart of the virtual machine manager did not play a recovery role, the fault of the first detection module is more serious or the fault did not occur in the first detection module, and therefore, further restart and recovery is performed on the operating system running the virtual machine manager; finally, through the two-level restart strategy, it is possible to more effectively deal with the abnormal situations of different first-level detection modules and provide a more appropriate restart recovery method.
[0064] Furthermore, in this embodiment, the operating system of the virtual machine manager is specifically a SOC system of a car, and the second detection module is arranged in the MCU system.
[0065] Specifically, for the SOC system, since it can only run a single virtual machine, when it is necessary to run multiple virtual machine related functions on the SOC system, it is necessary to run a virtual machine manager on it, and use the virtualization function of the virtual machine manager to run multiple virtual machines, including virtual machines related to automobile functional safety, that is, safety virtual machines, and non-functional safety related virtual machines. Therefore, in order to ensure the normal functional safety of the automobile, it is necessary to ensure the normal function of the virtualization function of the virtual machine manager, the safety virtual machine being run, and the first detection module according to the above method. As for the second detection module set on the MCU system, since it only needs to monitor the first detection module, the execution content is relatively simpler, so it is very compatible with the MCU for application scenarios with lower power consumption, simpler functions, and lower costs, which is helpful for program software settings and related costs, and the MCU also has high stability, which can ensure good detection accuracy of the first detection module, and provides a good foundation for the use of the first detection module.
[0066] In a second aspect, an embodiment of the present application also provides a virtual machine manager health management device.

[0069] A control module is configured to restart the virtual machine manager if there is an abnormality in the running state of the virtualization function; allow or control the virtual machine manager to start the operation of the secure virtual machine if there is no abnormality in the running state of the virtualization function; and if there is an abnormality in the running state of the secure virtual machine, restart the secure virtual machine first, and determine whether to restart the virtual machine manager based on whether there is an abnormality in the running state of the secure virtual machine after the restart.
[0070] Furthermore, in one embodiment, the virtual machine manager health management device further includes a new module for:
[0071] The second detection module is configured to, when the virtual machine manager runs the virtualization function, before determining whether the running state of the virtualization function is abnormal, perform the following steps:
