Lorelei - Enable QEMU to Leverage Native Shared Libraries

Learn how to extend QEMU's translation flow to enable hybrid execution by leveraging native shared libraries in this 28-minute conference talk from KVM Forum. Discover the innovative approach that allows QEMU to transfer control flow from emulated executable files to native dynamic libraries of the same version, executing expected procedures and correctly returning control. Explore the technical implementation details of this hybrid-execution scheme that demonstrates significant performance improvements, achieving several to tens of times faster QEMU emulation in common applications and notable FPS improvements in GUI applications. Understand the methodology behind enabling QEMU to call native shared library functions directly rather than emulating them, and examine the test data and benchmarking results that validate this performance optimization technique for virtualization environments.
