Avi Kivity (Hebrew: אבי קויתי) is a software engineer who created the Kernel-based Virtual Machine (KVM) hypervisor underlying many production clouds.[1][2] Following his work on KVM, Kivity developed the Seastar framework and the ScyllaDB database.[2][3] He co-founded the company ScyllaDB with Dor Laor; Kivity is CTO and an active project contributor.[2]

Career
Kivity began the development of KVM at Qumranet in 2006.[4] After Red Hat acquired Qumranet in 2008, Kivity joined Red Hat and continued as the lead developer and maintainer of KVM.[4][5]
After leaving Red Hat in 2012, Kivity co-founded a company called Cloudius Systems with Dor Laor.[2] Cloudius developed the OSv operating system for the cloud.[6] While at Cloudius, Kivity created the Seastar framework, an open-source (Apache 2.0 licensed) C++ framework for I/O intensive asynchronous computing.[2] Seastar later became the foundation for high performance distributed systems such as ScyllaDB, Redpanda, and Ceph.[7]
In mid-2014, Cloudius Systems was renamed to ScyllaDB, after its main product which is used for high-throughput database workloads that require low latencies. (Forbes) Kivity serves as the company's chief technology officer and contributes to the source code development of ScyllaDB as well as Seastar.[8]
