Building Vanilla Image

First, start Parallels 16 for Desktop and create a big-sur-vanilla VM by just creating it from a recovery partition in the UI.

Use VM's UI to change some settings:

1. Disable Lock Screen. Preferences -> Lock Screen -> disable "Require Password" after 5.
2. Disable Screen Saver.
3. Enable Auto-Login. Users & Groups -> Login Options -> Automatic login -> admin.
4. Allow SSH. Sharing -> Remote Login
5. Open Safari. Preferences -> Advanced -> Show Developer menu. Develop -> Allow Remote Automation.
6. Run sudo visudo in Terminal, find %admin ALL=(ALL) ALL add admin ALL=(ALL) NOPASSWD: ALL to allow sudo without a password.
7. optional Disable SIP by getting into Recovery Mode, Utilities -> Terminal and run csrutil disable.

Shutdown macOS.

Also change some VM settings:

1. Security -> Isolate VM from Mac.
2. Change any other settings.

Building Base Image

packer build -only=parallels templates/base.json

If you are getting prlctl error: Failed to register the VM: "big-sur-vanilla" is already registered. error, run:

prlctl unregister big-sur-vanilla

Building Xcode Images

To build an Xcode image (don't forget to setup DEVPORTAL_EMAIL and DEVPORTAL_PASSWORD since they are required by xcodes):

packer build -only=parallels \
  -var xcode_version="12.5" \
  -var devportal_email="$DEVPORTAL_EMAIL" \
  -var devportal_password="$DEVPORTAL_PASSWORD" \
  templates/xcode.json
