Features including no-network execution, CPU/RAM limits, guest-enforced timeouts, storage quotas, read-only input mounts, writable output mounts, and --unprivileged mode all worked as intended, with cold starts at 0.6–1.5 seconds and warm executions around 50 ms. Claude Fable 5, tasked with running the tests inside Claude Code for web, hit a nested-virtualization wall (no /dev/kvm) and creatively pivoted to GitHub Actions runners which expose /dev/kvm. Why: If you are building AI agent pipelines or SaaS features that execute user-provided code, smolvm offers a hardware-isolated alternative to Docker-based sandboxes with sub-second cold starts and 50 ms warm executions — worth evaluating against your current container approach, especially if you need strong isolation guarantees that shared-kernel containers do not provide. sandboxing code-execution ai-agents vm-isolation developer-tools
