is there any way to use cloud-init configs in python libvirt?
cloud-init require to create an iso, which seems that ovirt support
cloud-config: https://red.ht/2K1gBkn
But how can I do that by python libvirt?
I know I can mount iso by python libvirt to the VM, but the process of
creating iso file is the problem which if it is possible to enter the
cloud-config commands by libvirt could be better to me.

Cloud-init is out of scope of libvirt, so with libvirt, mounting the ISO is
your only option.
Outside of libvirt, I'd look at virt-install whether the cloud-init support
currently in place is sufficient for your use case. Bear in mind though that
cloud-init support in virt-install was added shortly after the 2.2.1 release
and we haven't had a new release since then, so you'd have to use virt-install
directly from git, maybe Cole can shed a bit more light on when the next
virt-install release is planned.

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
