Hi Adam, Thank you very much for your support. The explanation was very clear. From the printed information, it seems to be running fine. I have one more question: Can Fiasco be used as a hypervisor? From the example of l4re_VM-multi, it seems to have the ability to run multiple operating systems on a single platform, and in L4Re, only Fiasco runs in EL2 privilege level. I'm not sure if I understand this correctly, so I wanted to confirm with you. If it cannot be used as a hypervisor, what functionality does it lack that a hypervisor would typically have?
