🐛 Bug Fixes

macOS MicroVM Support - Fixed container execution in pure MicroVM mode on macOS

This release fixes a critical issue where containers couldn't execute in MicroVM mode on macOS. The fix implements proper rootfs mounting in the guest init process, enabling native MicroVM execution without Docker or Podman.

✨ Key Improvements

• ✅ Rootfs Mounting: Guest init now detects and mounts /dev/root virtiofs device
• ✅ Filesystem Pivot: Implemented proper pivot_root using chroot/chdir
• ✅ Library Discovery: Set DYLD_LIBRARY_PATH for libkrunfw on macOS
• ✅ Enhanced Debugging: Added filesystem diagnostics for troubleshooting
• ✅ Simplified Build: Streamlined OCI build RUN handler for macOS

🔧 Technical Details

Changes:

• guest/init: Added /dev/root virtiofs detection and mounting logic
• guest/init: Implemented pivot_root to switch to container rootfs
• runtime/vmm: Set DYLD_LIBRARY_PATH for libkrunfw discovery
• runtime/oci: Simplified macOS RUN handler

Workflow:

1. Detect /dev/root virtiofs device
2. Mount to /mnt/newroot
3. Move essential mounts (/proc, /sys, /dev)
4. Pivot to new root using chroot/chdir
5. Continue with normal container execution

🧪 Tested Platforms

• Platform: macOS (Apple Silicon)
• Runtime: libkrun (native virtiofs)
• Images: alpine:latest, ubuntu:24.04

📦 Installation

# Using Homebrew (recommended)
brew install a3s-lab/tap/a3s-box

# Or download binary from releases

🚀 Usage

# Run container in pure MicroVM mode (no Docker/Podman needed)
a3s-box run alpine:latest -- echo "Hello from MicroVM"
