Valgrind, for one, can easily provide information on allocations by calling function - both for leak checking (the "memcheck" tool) and heap usage profiling (the "massif" tool). There's apparently even a simple way to slip it under an existing QEMU VM from libvirt; there is a recipe for that in this presentation: https://www.linux-kvm.org/images/d/d2/03x07-Valgrind.pdf Regards Matthew Francis _______________________________________________ Spice-devel mailing list Spice-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/spice-devel
