KVM Address Space Isolation
Explore KVM Address Space Isolation in this comprehensive conference talk by Alexandre Chartre from Oracle. Dive into the intricacies of ASI, including its intuition, overview, applications, and lifecycle. Learn about KVM ASI usage, page-table filling techniques for statically and dynamically allocated buffers, and page table switching. Examine the interactions between ASI and interrupts, exceptions, page faults, and context switches. Understand the synchronization challenges across CPU threads, including scenarios with siblings running and not running ASI. Compare the KPTI model of control and data privilege with the ASI model of data privilege. Discover the process of partitioning global and local data, and review initial results from Aerospike YCSB benchmarks. Conclude with an overview of the current status and future prospects of KVM Address Space Isolation.
