Kernelized-QEMU: A Study of System-Level Virtual Layer in Linux Kernel

摘要

In this paper, we propose a way to implement the cross-platform system-level virtual layer in Linux kernel to achieve a higher performance, because, the virtual layer can be supported directly by the operating system and can directly interact with the real hardware without the performance cost of virtual device and user-space. As an example, QEMU is embedded into the Linux kernel. The tests show that the performance of kernelized-QEMU is better than QEMU.
