So, the error you're facing is not because the autoinst.xml file is
not recognised. It happens because the installation source is not
passed.

virt-install 1.5.0, which is the version present on CentOS 7.5,
doesn't seem to know the proper kernel URL argument to be passed to
different distros. So far it worked because it uses "method=URL",
which is what both CentOS 7 / Fedora (the ones we care about) use and
Ubuntu / Debian are special with regard to this.

OpenSUSE, though, requires "install=URL" to be passed. As it doesn't
happen, the installation asks for a specific installation source.

Okay, the way to go, IMHO, is patching lcitool to:
- Have a kernel-url-argument as part of the distro definition;
- Mount the extra-args based on that;

Mind that "method=" will always be appended but as long as we provide
the "install=" to the kernel command line, we're fine.

I'll cook some patches in the afternoon and post them.

An important question ... can't we have / use a CentOS 8 machine?
Would be lovely to not have to work those issues around on lcitool.

Best Regards,
