qemuでboot2dockerを起動。割と普通に動いた。VT-Xを使ってるかどうかを要検証
```bash
λ 'C:\Program Files\qemu\qemu-img.exe' create -f qcow2 harddisk.qcow2 32G
λ "C:\Program Files\qemu\qemu-system-x86_64w.exe" -m 4G -cdrom boot2docker.iso -name boot2docker -drive file=harddisk.qcow2,media=d isk,cache=writeback  -smp 2 -netdev user,id=user.0 -device e1000,netdev=user.0
```
