![]() So if you have libvirt, you have a high-level abstraction for multiple hypervisors (like KVM and Xen) which in turn know how to interact with various hardware implementations to actually have it act the way we want it. Then you get some higher level abstractions that allow you to use a virtualisation interface to make use of the system without having to re-invent that interface every time some new hardware gets released. ![]() Even a type-1 hypervisor like Xen would need to know a bit about the specifics of the hardware to know what features exist and how to use them. but you need a different software implementation to make use of it, even if only to use the different ISA and setup procedures.Įven within the same architecture you might need different low-level interfacing software to make use of it. ![]() Similar in functionality, different in implementation. ![]()
