Embodiment Construction
[0046] In order to make the above objects, features and beneficial effects of the present application more clearly understood, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0047]The following first briefly describes the existing hypervisor interrupt response process.
[0048] In the prior art, the pass-through in the hypervisor is to read the configuration file in .cfg format, find the VM corresponding to the interrupt number, and then call the hypercall of the hypervisor by the VM to configure the GIC and start the corresponding VM. The interrupt number corresponding to each VM in the configuration file is static and cannot be dynamically adjusted. If an interrupt corresponding to a VM wants to be used by other VMs, it must be handled by virtualization.
[0049] like figure 1 Shown is a schematic diagram of the existing Hypervisor-based interrupt response process. When the physical peri...
