KVM may not be the most paravirtualized feature-rich hypervisor out there but it still implements a lot. There are 'native' KVM features as well as Hyper-V, Xen and even Vmware emulation built-in. While the implementation bits usually live in KVM itself, userspace VMMs are still need to get involved. Despite the fact that enabling a single feature may be as easy as flipping a single bit, the 'when to flip' decision may be challenging. Upstream, developers are trying their best to deliver new features to as many users as possible but different users' needs, setups, 'legacy' requirements and ease of configuring should be taken into account. The talk will use QEMU as an example VMM. Several 'Native' KVM and Hyper-V emulation features will be looked at from 'enablement' perspective: who could benefit from it, what are the software/hardware requirements, how does the feature blend with other features, namely: with live migration.
