Re: [libvirt-users] Make discard='unmap' the default?

allowing a better choice.
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.
