You gave me an idea, so I went:

(yes, I had a qemu hanging around in my history. It is qemu-kvm, so it
might be a close cousin). Looking at the opens, I see one potential
config:

   openat(AT_FDCWD, "/etc/qemu/qemu.conf", O_RDONLY) = -1 ENOENT (No such file or directory)

It's a system config, but might be a start 🙂

No manpage for qemu.conf, alas.

@Franco: perhaps you could try a similar trick?

This was what I wanted to do, but without documentation about what the qemu.conf file should contain it is not possible to accomplish that.

Does anybody know the purpose of "/etc/qemu/qemu.conf"?
I have a file /etc/libvirt/qemu.conf on my system and it is very thoroughly commented, so self-documenting to some extent. It appears to have been installed by libvirt-daemon-driver-qemu so part of the libvirt/qemu family. But (on Debian 12) I find no /etc/qemu/qemu.conf.
