Guest:客户机系统,包括CPU(vCPU)、内存、驱动(Console、网卡、I/O 设备驱动等),被 KVM 置于一种受限制的 CPU 模式下运行。 KVM:运行在内核空间,提供CPU 和内存的虚级化,以及客户机的 I/O 拦截。Guest 的 I/O 被 KVM 拦截后,交给 QEMU 处理。 QEMU:修改过的为 KVM 虚机使用的 QEMU 代码,运行在用户空...

它需要支持虚拟化扩展的 CPU。 它是完全开源的。官网。 本文介绍的是基于 X86 CPU 的 KVM。 1.1 KVM 架构 KVM 是基于虚拟化扩展(Intel VT 或者 AMD-V)的 X86 硬件的开源的 Linux 原生的全虚拟化解决方案。KVM 中,虚拟机被实现为常规的 Linux 进程,由标准 Linux 调度程序进行调度;虚机的每个虚拟 CPU 被实...
