x86 Hypervisors and Emulators: Architecture, Features, and Performance
A comparison of x86 hypervisors (KVM, Hyper-V, Xen, VMware ESXi) and emulators (QEMU, Bochs), covering their architectures, features, and performance. Hypervisors leverage hardware virtualization for near-native performance, while emulators prioritize compatibility via software CPU translation at a speed cost. The article also covers live migration, snapshots, and GPU passthrough.
