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.

Note: Big Sur guests are not supported. Because Apple has changed the anatomy of the installer application, AutoDMG most likely won't be able to create a never-booted DMG for Big Sur. And since that is a dependency for vfuse, we are currently out of luck.

Note: Version 3.0 requires python3. If you wish to continue using vfuse with Apple's system python2, you should use the vfuse 2.2.6 release. However, at some point in the not-too-distant future, Apple is going to remove python completely from macOS, and you'll need to roll your own python3 to be able to use vfuse.

Options for installing python3: 1. Install the pkg downloaded directly from python.org. 2. Install Apple's CL Tools (either by downloading the pkg from Apple's developer site, or by invoking the shim at

/usr/bin/python3
). 3. Build your own copy of python (E.g. Greg Neagle's relocatable python tools). You'll need to ensure that this custom python is the default python in your
$PATH
.

Requirements

  • VMware Fusion 11.5.1 Professional or above
  • OS X 10.15+
  • Python 3+
  • A never-booted image created with AutoDMG.
  • (optional) Packer 1.1.1 (or above) for building a vagrant box.
  • (optional) qemu-img

             [--snapshot] [--snapshot-name SNAPSHOT_NAME] [-c CHECKSUM]
             [--list-templates] [--list-cache] [--clear-cache]

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.
