The Trapdoor in Your CPU: How Hypervisors Actually Work
Episode 4664
Published 2 days, 21 hours ago
Description
Ever wonder what actually happens when a virtual machine runs? This episode breaks down the hypervisor layer: the hardware trapdoor in your CPU, KVM's split personality, the VMCS data structure, and why virtio beats emulation. Then we contrast it with Docker's fundamentally different isolation model — and why the security trade-offs matter more than the marketing.
