C5 does not support nested virtualization but i3.metal allows using virtualization technology without nested virtualization.

Both i3.metal and c5 use the same underlying Nitro technology.

Wait, so even the "bare metal" i3.metal sits under a hypervisor? It would seem inaccurate to call it "bare metal" in that case.

No, Nitro refers to the whole technology stack as well as the hypervisor. *.metal instances utilize most of the Nitro technology stack, but not the Nitro hypervisor.
