a related question: i was wondering about the purpose of the
KVM_MEM_LOG_DIRTY_PAGES feature that is attached to physical memory
slots. Is that used so that you can get a compact bitmap of all modified
pages within a Qemu-emulated framebuffer, resulting in a delta update,
instead of having to do the full framebuffer update every time?
