Could you build this?
No Building a microVM hypervisor runtime on Apple Silicon that snapshots, restores, and forks full running Linux machines in tens of milliseconds requires low-level systems programming and hypervisor expertise.
What it would actually take: Requires deep integration with Apple's Hypervisor.framework or Virtualization.framework in Rust, C, or Swift. The hard part is implementing millisecond-level memory-state snapshotting, copy-on-write page table handling, and stateful VM forking without crashing the guest Linux kernel. It necessitates specialized systems engineering knowledge of ARM64 virtualization, MMU paging, and virtio device emulation.
