KVM is the kernel technology that allows user-space virtualization. qemu is the user-space program that takes advantage of kvm; sometimes, the binary is named qemu-kvm to express the relationship. Many people treat the terms interchangeably these days. If your distro ships qemu 2.1, you already have all that features that libvirt currently can drive on top of kvm. >>> * What version of qemu/kvm will have the core capabilities and >>> which min libvirt version would be sufficient ? >> Until patches materialize, it's hard to predict the future. > Could you clarify a bit more ..

You shouldn't be worried about qemu/kvm interactions as much as qemu/libvirt interactions. Right now, there are features in qemu that have not yet been exposed in libvirt; the features will be added as soon as someone volunteers to write the patches, but given the nature of volunteer work, it is hard to predict when that will be. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
