Abstract
Some embodiments concern a kernel bus system for building at least one virtual machine monitor. The kernel bus system can include: (a) a hyperbus; (b) user space components; (c) guest space components configured to interact with the user space components via the hyperbus; (d) VMM components having frontend devices configure to perform I/O operations with the hardware devices of the host computer using a zero-copy method or non-pass-thru method; (e) para-virtualization components having (1) a virtual interrupt module configured to use processor instructions to swap the processors of the host computer between a kernel space and a guest space; and (2) a virtual I/O driver configured to enable synchronous I/O signaling, asynchronous I/O signaling and payload delivery, and pass-through delivery independent an QEMU emulation; and (f) KVM components. Other embodiments are disclosed.
