Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less). Outside of EC2, many other providers are deploying on KVM. At my employer we sometimes use SR-IOV for direct network interface access, and NVMe for direct disk access.
