10 Years of Xen and Beyond
summary
Xen claims production scale use (AWS, Rackspace) and supports PV, HVM, PVH/PVHVM modes plus an ARM port with ~17,000 lines of arch‑specific code. Management surfaces include the XenAPI/XenServer stacks and an ISO appliance; a community survey of ~5,000 ranks robustness, performance, scalability, security top. The project prototypes disaggregation (device‑driver VMs, smaller TCB) and measures a driver‑domain restart at 275 ms restart, showing the approach works for isolation, live migration and usability tradeoffs.
