Patent attributes
Disclosed herein is hardware for easing the process of changing the execution mode of a virtual machine and its associated resources. By adopting the hardware, it is possible to trigger a change in the execution mode in an automatic way, without software intervention, and without interfering with the execution of other virtual machines. In addition, in case an error has occurred for a virtual machine and it is detected, the hardware can be used to disable the resources associated with that virtual machine and generate notification of the completion this operation to other hardware, which will complete the reset of the virtual machine. By adopting the hardware, the execution mode change is simplified and offers configurability and flexibility for a system running multiple virtual machines.
