Yes, exactly. All of KVM, HAXM and the OSX Hypervisor.Framework are basically providing APIs to user applications that encapsulate the CPU's virtualization capability so that you can use it to implement VMs without needing kernel privilege. They differ in how high a level of abstraction they provide (eg KVM does a lot more for you in the kernel, H.f punts to userspace for everything), but the principle is the same.
