Next Generation Interrupt Virtualization for KVM

Registered by Amit Shah on 2012-08-28

Virtualizing the x86 interrupt system is one of the most performance critical tasks a hypervisor has to
implement. For some workloads the overhead of a soft-virtualized APIC can mean a significant
performance degradation when running in a virtual machine.
This talk introduces a hardware extension to reduce this overhead. It will be explained how this
extension works and how we plan to integrate it into KVM.
