vfuse

This script takes a never-booted DMG and converts it to a VMware Fusion VM.

The germ of this idea came about, as all good ideas, and germs, do: while drinking beer. Specifically, I was tossing back drinks and tossing around ideas with Gilbert Wilson, and he mentioned that he uses the VMware CLI tools to convert DMGs to VMDKs based on a blog post he'd read. Intrigued, I asked Gil to email me the specifics. After seeing how potentially cool this was, I wrapped it up in this here terribly illegible, queasingly unpythonic script.

Requirements

• VMware Fusion 11.x Professional or above
• OS X 10.14+
• A never-booted image created with AutoDMG.
• (optional) Packer 1.1.1 (or above) for building a vagrant box.
• (optional) qemu-img

Creating a VM

Running vfuse does not necessarily require sudo rights, but if you don't want to be prompted in the GUI for an admin password, run it with sudo. (Escalated privileges is required to run the vmware-vdiskmanager binary, which vfuse uses.)

The only required argument is -i aka --input. Run thusly, it will create a vm called macos-vm.vmwarevm in the current working directory:

/usr/local/vfuse/bin/vfuse -i /path/to/dmg

See the wiki for more on how to use vfuse.

Caveats

vfuse is meant to be used with never-booted disk images created with AutoDMG. Using vfuse with a dmg created with Disk Utility is not something that has been tested, so you're on your own there. Likely, it's even more of a longshot with APFS.
