Virtualization.framework VM Limit

[brianmichel]

Currently, the Virtualization framework encodes a strict limit of 2 virtual machines running at once. This error is thrown when a 3 machine is attempted to boot, https://developer.apple.com/documentation/virtualization/vzerror/code/virtualmachinelimitexceeded.

Is the containerization framework subject to this limit as well since the framework is effectively booting virtual machines as well?

I'm thinking about the world where people will be running macOS virtual machines and containers on the same host and how confusing it might be to get this kind of error when you're just running a container.

Howdy @brianmichel, the 2 VM limit is a system wide macOS guest restriction only so would not apply here as much where we're running Linux guests.

Oh interesting, so this limitation comes from the macOS kernel itself or something like that when it's booted by the system hypervisor?

The 2 VM limit for macOS guests corresponds to the end-user license agreement

I'm going to close this, but if this project does impede on using another Virtualization.framework project (I hope not 😅) please re-open!
