Abstract
Interrupts enable computers to multitask, respond
to external devices, and efficiently execute critical operations.
Virtualization requires the host to intercept and mediate hardware
access requests from virtual machines to isolate and manage
virtualized resources effectively. However, such host interposition
introduces a certain level of overhead for handling interrupts.
This writeup aims to examine three papers focusing on efficient
interrupt handling for I/O devices in x86 virtualized environments
and discuss their tradeoffs.
