Sorry, something went wrong.
Fix targeted gvproxy kill to use tracked PID from runtime state instead of pkill, gate diagnostic dump behind OPENSHELL_VM_DIAG env var, stream SHA-256 hashing to avoid buffering entire files, clarify operator precedence in env var validation, replace hand-rolled JSON parser with serde_json, deduplicate required_runtime_lib_name(), and add openshell-vm to AGENTS.md architecture table.

- Gate krun_add_net_unixgram FFI type, struct field, and VmContext method behind #[cfg(target_os = "macos")] to eliminate dead_code warnings on Linux - Add krun_add_net_unixstream FFI binding and add_net_unixstream VmContext method for Linux SOCK_STREAM networking via gvproxy QEMU listener - Switch gvproxy launch flags: -listen-qemu (Linux) vs -listen-vfkit (macOS) - Add recover_stale_kine_db: removes corrupt or bootstrap-locked SQLite kine database before boot so k3s always starts with a clean schema - Drop version segment from rootfs and runtime cache paths to avoid stale directories accumulating across upgrades - Improve build-libkrun.sh: two-phase kernel config merge using merge_config.sh and auto-detect LIBCLANG_PATH for clang-sys on Debian/Ubuntu - Ensure libkrunfw.so.5 soname file is present alongside versioned artifact - Add bundle-vm-runtime.sh task and vm:bundle-runtime mise target - Pin AGENT_SANDBOX_IMAGE to updated digest - Add pyelftools dev dependency
…ed template Each gateway instance now gets its own rootfs extracted directly from the embedded tarball, eliminating the shared template rootfs that all instances previously cloned from. The default (unnamed) gateway is now treated as a named instance with name "default", removing all Option-based branching. - Replace ensure_rootfs_extracted() with extract_rootfs_to(dest) in embedded.rs - Rewrite ensure_named_rootfs() to extract instead of clone - Remove clone_rootfs() and DEFAULT_GATEWAY_NAME - Default --name CLI arg to "default", simplifying all call sites - Remove dead default_rootfs_dir() from paths.rs

Summary
Adds the
openshell-vmcrate — a new microVM runtime that uses libkrun to boot lightweight VMs with hardware isolation. On macOS ARM64 it leverages Apple's Hypervisor.framework; on Linux it uses KVM. This provides a single-binary alternative to the Docker/k3s-based gateway deployment.Changes
