If you're on Fedora host, we have packages you can use in a copr repo:
https://copr.fedorainfracloud.org/coprs/g/virtmaint-sig/sev-snp-coconut/

Usage docs are in the web landing page. VM creation isn't covered but it
was something like:

wget
https://download.fedoraproject.org/pub/fedora/linux/releases/38/Cloud/x86_64/images/Fedora-Cloud-Base-38-1.6.x86_64.qcow2
sudo virt-install --boot uefi --os-variant fedora-38 --cloud-init --disk
Fedora-Cloud-Base-38-1.6.x86_64.qcow2
(inside VM: login, dnf update, enable the copr, install kernel-snp-upm)

And then follow copr instructions. Once you've got a guest booting,
start swapping out packaged components for locally built versions as
needed, like passing `coconut.sh -svsm /path/to/your/coconut.bin`
