UnverifiedVM-level isolation (such as Firecracker microVM) provides the strongest isolation guarantees but introduces higher startup and communication overhead.77% similarUnverifiedMicroVMs leverage hardware virtualization capabilities (such as KVM, Hyper-V, and macOS's Hypervisor framework) to provide an independent virtual kernel for each workload.77% similarUnverifiedAgent sandboxes are typically based on lightweight virtual machine (microVM) technology, such as Firecracker or Cloud Hypervisor, providing complete kernel isolation at the hardware virtualization level.76% similarUnverifiedKVM performs full virtualization at the hardware level; each VM has an independent kernel space, supports nested virtualization, and provides stronger security isolation.75% similarUnverifiedFirecracker can start a microVM with an independent kernel in milliseconds, preventing malicious code from escaping while avoiding the heavy startup overhead of traditional virtual machines.73% similar
