Writing a hypervisor from scratch
Seiya Nuta, Vercel Inc.

Hands-on tutorial covering fundamental concepts and practical implementation techniques for hypervisor development.

Abstract: Hardware-assisted virtualization technologies like Intel VT and AMD SVM have long been viewed solely as mechanisms for running virtual machines. This talk challenges the preconception - it's actually a hardware-assisted try-catch mechanism, where the hypervisor effectively behaves as a "catch" block for VM exits. Through this metaphor, we will revisit virtualization from scratch, explore recent virtualization-based applications, rethink what hardware-assisted virtualization is, and brainstorm what we could invent in the near future.
