This needs to be split up better into multiple patches - there are many
examples of how to do that. Just see how patches were done the last time
someone added a new transport type. Typically the docs/schemas,
src/conf, src/util, xml2xml tests would go in one patch while the
src/qemu, xml2argv patches in a second patch. Each patch would be
compile-able and testable.
As pointed out before, you're still not completely following the
contributor guidelines w/r/t commit message. Furthermore, when you
"update" your patch and post a followup version, you should make a "v2"
or "v3" or "v4" in your header and then either in the cover letter or
after the '---' describe what changed since the previous patch.
The first patch would also need to update docs/formatdomain.html.in and
the commit message should also describe the new XML being added - there
are many examples.

Furthermore, if it must be kept here, then since the <attribute>
sequence is repeated 3 times, may as well make a definition for it and
then use it everywhere rather than cut-copy-paste in each place.

This is the <hostdev> <source>, but I don't believe that it's actually
tested as there's no XML that I see... I also didn't check to see
whether you parsed and formatted both <disk> and <hostdev> in domain_conf...

The virStorageNetHostTransportTypeToString should be used and not "iser"
directly.
This and the Parse makes no sense when compared to the 3 possible
options. That is, it's possible to have "tcp", "rdma", and "iser", but
you only care about "iser".

This doesn't make sense - the error message doesn't match the if
conditions. Check your usage of && to considering what the other
options are and what's being checked here.

Consider using a local @transport... I didn't check if src->hosts could
be NULL here...

<sigh>
At least you attempted the parse code - it's largely forgotten.

Why do both <source> and <host> get the transport='iser'?
Since patches weren't well formed, I didn't dig in too deep into
checking what you've done vs. how it should be done.
Does "auth" really have any bearing here? That is, is it really
necessary to supply both two tests where one only adds auth that has
nothing to do with iser transport?
