QEMU has options to configure the size of the L2 and refcount caches for the qcow2 format. However, choosing the right sizes for a particular disk image is not a straightforward operation since the ratio between the cache size and the allocated disk space is not obvious and depends on the size of the cluster and the refcount entries. This document attempts to give an overview of both caches and how to configure their sizes.
