These patches add a --enable-malloc-stats configure options, which will make qemu trace its memory allocations. A new monitor command dump-malloc-stats lets the user dump them to a file.
Using statistics with KVM depends on the patch I posted recently to use qemu_free consistently. However, there is no regression without the configure flag.
