vm虚拟机系统设置的内存会占用主机内存。
vm虚拟机虚拟化的定义:
虚拟计算机系统被称为“虚拟机”(VM):紧密隔离的软件容器,内部装有操作系统和应用程序。每个独立的VM都是完全独立的。将多个VM放在一台计算机上,可使多个操作系统和应用程序仅在一个物理服务器或“主机”上运行。
软件薄层将虚拟机与主机分离,并根据需要将计算资源动态分配给每个虚拟机。
根据你的需求,虚拟机会获取计算机资源。这里的资源包含内存资源。
但是vm虚拟机的资源分配是动态的,所以当你不使用时,不会占用你的内存资源。
扩展资料:
Virtual Machines Explained(虚拟化定义):
A virtual computer system is known as a “virtual machine” (VM): a tightly isolated software container with an operating system and application inside. Each self-contained VM is completely independent. Putting multiple VMs on a single computer enables several operating systems and applications to run on just one physical server, or “host.”
A thin layer of software called a “hypervisor” decouples the virtual machines from the host and dynamically allocates computing resources to each virtual machine as needed.
