Hello! > Can you explain what this setting actually does? Of course. It allows to choose GIC version used by ARM 'virt' machine. By default it's 2, but you can now set it to 3. Actually, initially i proposed another machine type, like 'virt-v3', IMHO this would be more logical because this is kind of different architecture. But Peter Maydell disagreed and insisted on option. So we have an option. > When would apps like virt-manager want to enable it? When choosing 'virt' machine type for ARM architecture.
