Summary
TencentCloud open-sourced CubeSandbox, a secure sandbox service for AI agents built on RustVMM and KVM that boots in under 60ms with less than 5MB memory overhead per instance. It provides hardware-level isolation via dedicated guest OS kernels, supports E2B SDK compatibility for zero-code migration, and includes features like a credential vault, egress control, and a Copy-on-Write snapshot engine for event-level rollbacks. Benchmarks show sub-150ms P99 cold start times under 50 concurrent creations, enabling thousands of agents per node.
