and other less-relevant information.

our guidance of how to send patches I've pointed you to:

Both hunks above don't really move the validation anywhere. It just
moves one condition to different file which in fact decreases
readability of the code.
Additionally virDomainStorageNetHostSocketValidate returns 0 or -1 but
you don't check it explicitly, which further obscures the code.
This part of the patch doesn't make much sense.

While this bit technically doesn't really move the validation out of the
parser [1] this is an acceptable change.
[1] moving the validation out of the parser means that the error is not
raised from the parser altogether.

The only caller passes graphicsType via:

Since it's the only use of 'graphicsType' in the caller move that bit
here and remove the argument.

Both hunks above don't really move the validation anywhere. It just

Just for the record: I highly suggest you take a look how XML parsing is
done. The virDomainDefParseNode() looks like a good start.
Long story short, XML parsing is done in three steps:
1) the actual parsing, when virDomainDef (or any other definition struct
for other objects, like virNetwork, virNodeDev, etc.) is filled with
data from given XML document,
2) PostParse - when missing information is filled in (e.g. MAC addresses
are filled to vNICs), and finally
3) Validate - when the whole definition struct is checked for errors
(e.g. there are no devices with duplicitous alias).
Now, we have a lot of old code which combined these three steps into one
and we are working slowly to get rid of it, but hopefully now you see
why this hunk in particual isn't step in the right direction.
