To be clear, I'm not suggesting that the "default defaults" be changed, I would just like to change the default on my personal system. It sounds like you're saying that libvirt expects virt-manager to override these settings (if it wants to), but virt-manager doesn't provide any way to do so, since it just uses the defaults from libvirt/ QEMU.
