The short answer is yes.
I have put together an ansible role to build cloud init based qcow 
images and does the most basic of configs based on the vars passed to 
the role.

you need to create an ISO with 2 files: "meta-data" and "user-data"

then run something like the folowing command to create the ISO.
         genisoimage -output myvmconfig.iso -volid cidata -joliet -r 
cloudinit_src_dir/

Then you create and start your VM with the ISO attached.
On the first reboot of the VM you could remove the ISO so long as 
cloud-init is not going to run again.

My work was done using ansible and the standard virsh commands so your 
build process will be different
