Kernel as Hypervisor: Andrea Arcangeli

You’re now with Qumranet which is the company behind
KVM. Can you briefly tell me about the design of KVM and how that
differs from previous virtualization approaches such as Xen and
VMware?

“I really like this approach because when you start doing really
advanced virtualizations features like swapping the guest memory
and swapping different parts of the address space you start using
the same algorithms that the normal Linux kernel is using for
swapping normal processes and this avoids duplication of
algorithms, and when the kernel is optimized to do better swapping
the virtual machine gets the same benefits…”
