For creating a snapshot using virsh command only supports the format qcow2, you cannot create a snapshot for the VM's that has qemu image format as raw. You need to create a qemu image format as qcow2 before the installation of VM by using below command

qemu-img create -f qcow2 /var/lib/libvirt/images/desktop.qcow2 20G
