As a user of Docker Toolbox, I am asked if I want to import the images/containers from my Toolbox default machine during the initial install/setup of Docker for Windows (Hyper-V), or post-install via Settings > Reset > Reset to Toolbox default machine content…
Expected behavior
Docker Toolbox default machine images and containers are migrated to Docker for Windows
Actual behavior
Error occurs immediately (<1 second) after starting the import. No images or containers are migrated.
Information
Error notification says: "Failed to to migrate volume: <path to default/disk.vmdk>"

It looks like the path argument being passed to qemu-img.exe isn’t quoted and the space in the disk.vmdk path is causing it to be treated as multiple arguments instead of just one.
Steps to reproduce the behavior
- Create a user whose home directory contains a space (e.g. “John Doe”)
- Install Docker Toolbox
- Upgrade to Docker for Windows
- Attempt to migrate the Docker Toolbox content into Docker for Windows
