VerifiedContainers share the host machine's kernel rather than simulating complete hardware, so startup speed can reach the millisecond level, with resource overhead far lower than traditional virtual machines.79% similarUnverified即时存档将整个虚拟机的完整状态（包括CPU寄存器、内存内容、GPU状态等）序列化为文件，其格式完全由模拟器定义，同一游戏在不同模拟器中的即时存档互不兼容79% similarUnverifiedVirtual machines rely on a hypervisor to emulate a complete computer, with the guest having its own kernel, forming a stronger security boundary than containers against the host, but with significantly higher memory and startup overhead.78% similarUnverifiedVirtualization technology achieves near-native performance by allowing guest code to execute directly on the physical CPU, whereas an emulator reproduces the target device at the register level without relying on equivalent functionality of the host hardware.78% similarVerifiedThe essential difference between container technology and virtual machines is that containers share the host machine's operating system kernel and achieve isolation and resource limiting through Linux's Namespace and Cgroup mechanisms.77% similar
