Virtual 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.

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% similarVerifiedContainers share the host machine's kernel, while virtual machines emulate complete hardware.78% similarUnverifiedVirtual machines simulate a complete computing environment at the hardware level through a Hypervisor, and there have historically been multiple virtual machine escape vulnerabilities (such as the Venom vulnerability).78% similarUnverifiedMicroVMs leverage hardware virtualization capabilities (such as KVM, Hyper-V, and macOS's Hypervisor framework) to provide an independent virtual kernel for each workload.75% similar
