> I downloaded the qemu image from
> https://ftp.gnu.org/gnu/guix/guix-system-vm-image-1.0.1.x86_64-linux.xz.
> It had a valid signature.
>
> After booting the machine with qemu 3.1 (I'm on debian-amber):
> `qemu-system-x86_64    -net user -net nic,model=virtio    -enable-kvm -m
> 512    -device virtio-blk,drive=myhd    -drive
> if=none,file=./guix-system-vm-image-1.0.1.x86_64-linux,id=myhd`
>

-m 512 looks a bit low.

Could you check if the disk is full? The image is small should be resized
