摘要： A system and method for providing dynamic device virtualization is herein disclosed. According to one embodiment, the computer-implemented method includes providing a hypervisor and one or more guest virtual machines (VMs). Each guest VM is disposed to run a guest user process and the hypervisor is split into a device hypervisor and a compute hypervisor. The computer-implemented method further includes providing an interface between the device hypervisor and the compute hypervisor. The compute hypervisor manages an efficient use of CPU and memory of a host and the device hypervisor manages a device connected to the host by exploiting hardware acceleration of the device.

摘要： A system and method for providing dynamic information virtualization (DIV) is disclosed. According to one embodiment, a device includes a dynamic optimization manager (DOM), a process and memory manager (PMM), a memory, and a host device driver. The device starts virtual functions after booting to allow a virtual machine (VM) running a guest operating system to identify the virtual functions and load virtual drivers of the virtual functions. The PMM allocates a unified cache from the memory to facilitate coherent access to information from storage and network resources by the VM. The host device driver enables a guess process in the VM to access the information stored in the unified cache in a secure and isolated manner.
