UnverifiedgVisor implements a complete Linux kernel interface (called Sentry) in user space, so that system calls within the container do not directly reach the host kernel.65% similarUnverifiedgVisor intercepts system calls through a user-space kernel, while Firecracker provides micro-VM-level strong isolation based on KVM; both seek a balance between security and startup speed and are suitable for Agent services sensitive to cold-start latency.64% similarUnverifiedSandbox environments (such as gVisor and Firecracker) introduce additional CPU overhead for security isolation, and each concurrent Agent instance needs to maintain an independent execution context.61% similarUnverifiedgVisor 和 Firecracker 是轻量级虚拟机技术，在容器与宿主内核之间加一层隔离；seccomp 可以白名单方式限制进程执行的内核调用58% similarUnverifiedOnce the system is live, Nova monitors service quality around the clock and proactively proposes improvement plans for human approval (human-in-the-loop design)58% similar
