All UNIX operating systems support a system of virtual memory (VM).
所有unix操作系统都支持某种虚拟内存(VM)系统。
Such as when the VM executes code in kernel mode; then VMWare has to carefully translate the memory mapping and permissions in order to simulate the VM's virtual CPU correctly.
比如，当VM以内核模式执行代码时；为了正确地仿真VM的虚拟cpu,VMWare必须谨慎地转换内存映射和权限。
Tmpfs also makes use of the disk swap space for storage, and of the virtual memory (VM) subsystem when requesting pages for storing files.
tmpfs还使用磁盘交换空间来存储，并且当为存储文件而请求页面时，使用虚拟内存(VM)子系统。
Virtio has also been used in High-Performance Computing (HPC) research to develop inter-virtual machine (VM) communications through Shared memory passing.
virtio还应用在High - PerformanceComputing (HPC)研究中，以开发出通过共享内存传递的inter -virtual machine (VM)通信。
