Memory Exhaustion (OOM) running Windows 11 VM on 8GB Apple Silicon (M1)

### Description

I am experiencing OOM issues when attempting to run a Windows 11 ARM64 VM on a MacBook Air M1 with 8GB ram. The virtualisation process consumes all available system memory, leading to a macOS "out of application memory" warning, forcing the process to be killed or suspended.

The Windows 11 VM should run reasonably well without exhausting host memory. According to [Microsoft's official Windows 11 minimum hardware requirements](https://learn.microsoft.com/en-us/windows/whats-new/windows-11-requirements), the OS requires only 4 GB of RAM and 2 cores.

### Environment
- Host OS: macOS Tahoe 26.5.1
- Host Hardware: MacBook Air M1, 8GB RAM
- Guest OS: Windows 11 ARM64
- Hypervisor/Emulator: QEMU (qemu-system-aarch64)

Reproduce the Windows 11 ARM64 VM on the stated 8GB Apple Silicon setup, starting with the qemu-system-aarch64 command shown in the log and its -m 3072 setting. Compare host memory use during startup and determine a measurable memory-safety expectation; done means the VM no longer exhausts host memory under the reported conditions, with the relevant evidence or affected entry point documented.
