## VM Info File
Each VM writes a metadata file at `state/vm-*/info` with the following fields:
- `vm_id`: unique identifier for the VM instance.
- `pid`: Firecracker process ID.
- `created_at`: timestamp when the VM was launched.
- `guest_ip`: IP address assigned to the guest.
- `tap`: host TAP interface name attached to the bridge.
- `api_sock`: path to the Firecracker API socket.
- `log`: path to the Firecracker log file.
- `base_loop`: loop device backing the base rootfs (if present).
- `cow_file`: copy-on-write image file (if present).
- `cow_loop`: loop device for the COW image (if present).
- `dm_name`: device-mapper name for the merged rootfs (if present).
- `dm_dev`: device-mapper device path for the merged rootfs (if present).
## Log Notes
- `PCI: Fatal: No config space access function found` and `MissingAddressRange` lines are expected with `pci=off` in `run.sh`.
- `SELinux: Could not open policy file ...` is expected in the minimal rootfs.
