VBox 3c: VirtualBox context in the integration test harness #276

Parent

#269

What to build

The integration test harness runs against VirtualBox: a VirtualBox context restores the snapshot, starts the VM headless, creates the driver for the selected access method, and powers off on teardown. First ground-truth test: reads match the core dump.

Acceptance criteria

• Harness runs with the VirtualBox driver and MachineDebugger method selected
• Read-correctness test: every RAM page read while paused is byte-identical to the dumpvmcore core file
• Same test passes on a guest configured with more than 4 GiB of RAM, and the max physical address exceeds 4 GiB
• The context is parameterised by access method so VBoxVMI can reuse it
