KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.
We use KVM as our Type-1 hypervisor and the Cloud Hypervisor as our VMM. Needless to say, Ubicloud wouldn't have been possible without mature open source solutions for cloud virtualization.
