Support for additional advanced/developer options?

[jorgschulze73]

I was wondering if there's any plans to support additional developer-friendly options such as booting with a custom rom? (useful to load custom kexts inside the VM or to boot iPhone VMs)

It should be just a matter of invoking the private method _setROMURL on the VZMacOSBootLoader object.

I think it could be integrated like this:

• During VM creation, VirtualBuddy can copy the correct AVPBooter.vmapple2.bin from the host to the VM's storage
• When VM is launched, it will use that local AVPBooter.vmapple2.bin via _setROMURL

This way a developer could perform the required patches locally, without having to mess with SSV, APFS snapshots and so on.

Thank you!

Most of the advanced options enabled by those SPI methods require private entitlements which can't be had by a regular customer app like VirtualBuddy.

You can build your own tool or custom build of the app with those private entitlements if you want to, but to run them you'd have to completely disable all code signing security on the host Mac, which I don't advise doing.
