Qemu config file -cpu host option

[Dmitrii Bundin]

QEMU version 6.1.0 

I have a QEMU configuration file qemu.cfg containing the following section:

[accel]
accel = "kvm"

So to run qemu I use the command

qemu-system-x86_64 -readconfig qemu.cfg -cpu host ubuntu.img

Is there a way to put -cpu host into the config file as well? I tried 

[accel]
accel = "kvm"
cpu = "host"

But got the following error:

qemu-system-x86_64:qemu.cfg:15: Property 'kvm-accel.cpu' not found
