Nested KVM virtualization

Operating system

Ubuntu 24.04

Description

I have this warning :

Warning: Nested KVM virtualization detected, this might cause issues running macOS!

The service start well, but then during the installation process after 1 min machine crash, mac os restart. I am unable to complete the installation.

Any idea ?

Start with the Docker Compose configuration and the startup log, especially the nested KVM warning and the macOS boot messages. Reproduce the installation failure on Ubuntu 24.04 with the shown AMD EPYC and Docker setup, then compare behavior with the project's documented virtualization requirements. Done means identifying a supported configuration or a reproducible project defect with clear diagnostic evidence.
