This was easy because I’d installed QEMU earlier on my system via Homebrew, so it was easy to convert the VMDK (the VMware disk image) to a RAW image image:

> qemu-img convert -f vmdk puredarwinxmas.vmdk pd.raw

This captures the contents of the VMware image into a raw image in some (unbeknownst to me) format. You can then write this to an ISO file:

> dd if=pd.raw of=pd.iso

That’s it. You can then mount this ISO, put it up for download, or whatever. This shouldn’t be limited to PureDarwin, and should work for most VMware disk images as long as it is stored as a VMDK file.
