This patch series introduces the support for new s390x 'loadparm'
feature. The 'loadparm' can be used to select the boot entry to
boot from, for a boot device.
Here is a link to the QEMU patches:
https://lists.nongnu.org/archive/html/qemu-devel/2017-05/msg00192.html
ChangeLog
---------
v2 -> v3:
- Updated news.xml and formatdomain.html.in with a more architectural
description of loadparm (patch 1)
v1 -> v2:
- Rebased the patch series on the latest master, commit
2f69dd3 virfiletest: include linux/falloc.h
Thanks

Perhaps just add a sample here to show where the XML gets added.

New subject: [libvirt] [PATCH v3 2/3] qemu : Add loadparm to qemu command line string
Introduce a new QEMU capability for loadparm and if the capability is
supported by QEMU then append the loadparm value to "-machine" string
of qemu command line.

I was wondering why there weren't any changes to the tests/
qemucapabilitiesdata/*s390*.xml files... Until I realized this is a
really new feature for qemu... As in post 2.9 and there is no 2.10
*.replies and *.xml file yet created...
The *.xml files add the <flag name=...> entries for whatever qemu
versions the machine loadparm=xxx flag can be found in order to define
the flag to create the .args. But you have .args in v3, which is
confusing (it's late too).
See commit '6b5c6314' for a recently added capability for kernel-irqchip
which modified a number of tests/qemucapabilitiesdata/* output .xml files.
There's also "tests/qemucapsprobe /path/to/binary >caps.replies" which
is what's used to generate those .replies files (those could be added as
part of this or the xml2xml commit).
Sometimes the patch order choice is have patch 1 have all the necessary
flag stuff done, patch 2 the xml/rng/docs, patch 3 the qemu, and patch 4
the news.xml.

Is this required to be the first parameter to -machine? If not then
perhaps it'd be better to place it at the end after the irqchip stuff.
Also, you could move the CapsGet into here so you can keep the void
designation for the called function.
Was there ever thought to adding loadparm to the machine XML? What's the

okay
Was there ever thought to adding loadparm to the machine XML?
What's the
reasoning to not have it there. If it's only valid for bootindex=1,
then it's far easier to check if the machine XML has it defined rather
than perusing the disk/network lists (which could be lengthy) only to
fine none. If the concern is some other arch allowing a different
bootindex to have loadparm, then the simple decision there is to have a
"loadparm_bootindex=#" value that would match the disk bootindex=# value.
I am not sure what you mean here? By machine xml do you mean <os> xml?

Sorry I was too lazy to go make the cross reference near the end of the
day/review. Guess I was thinking more <os> related though...
I see in <os> there's a <boot> subelement which has a relationship with
the <boot> subelement for <devices>...[<interface>|<disk>]...
I think I was just trying to make sure that adding <loadparm> to
<devices> would make sense "in the long run" and what other
implementations were considered and not taken because of some drawback.
Given the description I've read and the implementation that searches
either disk or network lists looking for bootIndex = 1, I wonder if the
<os> <boot dev='xxx' > should be modified instead. Was that
considered
- what were the drawbacks? Can bootparm conceptually be added/used for
a non boot disk?
I'm not requesting one way or another - I'd just like to be sure the
question is answered before perhaps someone else asks it now or much
later when this isn't so fresh in your mind.

Yes, the <os> has <boot> subelement, but it can be tricky to specify the
order of the boot device.
I think I was just trying to make sure that adding <loadparm>
to
<devices> would make sense "in the long run" and what other
implementations were considered and not taken because of some drawback.
The per device boot subelement was added to simplify the boot device
order. That's why I thought it made more sense to add it to the per
device boot element. Also from a user's perspective it's easier to
specify the loadparm when specifying the boot order.
Given the description I've read and the implementation that
searches
either disk or network lists looking for bootIndex = 1, I wonder if the
<os> <boot dev='xxx' > should be modified instead. Was that
