Xen 4.7 Test Day Instructions for RC2+ : Call to action for people who added new features / functionality to Xen 4.7

Xen 4.7 Test Day Instructions for RC2+ : Call to action for people who added new features / functionality to Xen 4.7

[Lars Kurth]

Hi everyone,

I updated http://wiki.xenproject.org/wiki/Xen_Project_Test_Days and created http://wiki.xenproject.org/wiki/Xen_4.7_RC_test_instructions (note that we only have one page for all RC's now to avoid unnecessary copy and pasting).

For those who want new features to be tested, please expect to 
a) Explain what to test (a very short description of the feature)
b) Add some instructions on how to test (e.g. some command line instructions)

You can add a new headline (an example is marked with TODO) to either
- http://wiki.xenproject.org/wiki/Xen_4.7_RC_test_instructions#Specific_ARM_Test_Instructions
- http://wiki.xenproject.org/wiki/Xen_4.7_RC_test_instructions#Specific_x86_Test_Instructions
- OR http://wiki.xenproject.org/wiki/Xen_4.7_RC_test_instructions#RC_specific_things_to_test (under a specific RC heading)

I will start promoting Test Days from early next week (on the blog, but also on the mailing lists). The more specific test instructions for Xen 4.7 related features, the better the coverage will be and the more likely people are to actually test.

Best Regards
Lars

[Lars Kurth]

Hi all,

I added the following sections based on git logs to man pages. Authors are on the CC list and should review and modify (or suggest edits by replying to this thread). I added/updated/added TODO's to:

I do have some questions, to ...
- Konrad/Ross: is there any documentation for xSplice which I have missed?
- Julien: Any ARM specific stuff you want people to test?
- Doug: are there any docs / tests for KCONFIG you want to push
- George: are there any manual tests for credit 2 hard affinity, for hotplug disk backends (drbd, iscsi, &c) and soft reset for HVM guests that should be added?

For the following sections there are some TODO's - please verify and modify and once OK, remove the TODO from the wiki pages.

VCPU-PIN (Juergen Gross)
- http://wiki.xenproject.org/wiki/Xen_4.7_RC_test_instructions#-f_option_for_xl_vcpu-pin

RTDS (Meng Xu, Chong Li)
- Meng, you mention improvements to the RTDS scheduler in another thread
- Are any specific test instructions needed in http://wiki.xenproject.org/wiki/Xen_4.7_RC_test_instructions
- http://wiki.xenproject.org/wiki/Xen_4.7_RC_test_instructions#RTDS_scheduler_improvements

COLO (Wen Congyang)
- http://wiki.xenproject.org/wiki/COLO_-_Coarse_Grain_Lock_Stepping

Are there any other big items that are missing?

Lars

Hard affinity tests shouldn't be too difficult to add in.  There are
certainly tests for drbd and iscsi, but I'm not personally that
familiar with them, it would basically be, "If you use drbd or iscsi
backends, try HVM guests". :-)

Soft Reset was added in by Vitaly, I believe; I listed it because I
saw it in the git history.

George, if you are not into this already, I can do it.

One thing (for Lars). There's a section about "-f option for xl vcpu-
pin". I don't see what's its purpose and what and how one should test
this.

Perhaps Juergen has better ideas, but I think it should just be
removed.

Regards,
Dario

+1

The only test I could imagine would be to test whether the "-f" option
is accepted.


Juergen

I've added a section about the new features in Credit2:
http://wiki.xenproject.org/wiki/Xen_4.7_RC_test_instructions#Credit2_runqueue_arrangement_and_hard-affinity_support

And I've also added more info and more examples about RTDS:

General testing of Xen on the boards we are supporting.

We may also want some testing on ACPI, which will be in tech preview for 
Xen 4.7. However this is requiring platform with ACPI 6.0 (or later). If 
I remember correctly, none of the ARM64 platform we support fulfill this 
requirement. Steve, do you have any platform in mind?

Shannon, which platform have you used for the ACPI development? Was it 
the Foundation Model?

If so we would need to write down (or update) a wiki page with the 
instructions to boot Xen on the model.

Cheers,

That is already in the boilerplate, but I can make it more prominent

Good point. Stefano, how can it be tested? Is checking the date in the 
guest enough?

Yes, it is enough, provided that the guest doesn't run ntpdate (or
doesn't have access to network).

There is a wiki page[1] written by Parth. It needs to update it.

I verified the text in the wiki, added one comment "which will not
invoke the scheduler unnecessarily" for the event-driven model.

I removed the TODO in the RTDS section in the wiki.
Please let me know if I need to do something else.

Thank you very much!

I've updated http://wiki.xen.org/wiki/XSplice

to have better layout and data. I will have a sub-section on how to test it.

Not at this time. Unless someone has an idea for what they'd like to see
and I'll go off and do it.

This is not specifically related to test-day/test-instructions, but as
far as I can tell:
 1) there's no wiki page saying that we have Kconfig and how to use it,
 2) we haven't blogged about it.

I'd say we should do both, but I guess 2 depends on how much we really
want this possibility of changing the default configuration to be
advertised. As I think the answer is "not much", we may better don't
blog.

But at least 1, I think it should be there.

As a matter of fact, I still haven't given explicitly using Kconfig on
Xen a try yet (despite wanting to), so I'm not sure about the
content... But just something simple stating that it's there, what it
covers (Xen only vs. Xen+tools, etc), how to achieve what's been the
default so far, how to achieve something slightly different...
something like this.

Thanks and Regards,
Dario

Hi all,

I cleaned the test page page up as much as I could and have time for and incorporated your input: see http://wiki.xenproject.org/wiki/Xen_4.7_RC_test_instructions 

Obviously there are still gaps, which could be filled. I did focus on top-level features and features which have a command-line impact. 

This means, that I didn't cover features such as VT-d posted interrupts, VMX TSC Scaling, huge PV-domains, ... If you do want to get them included and they are testable (even if as simple as "boot Xen <or whatever operation is needed> on HW with <xyz> feature (or even better HW of <xyz model>) in <foo-bar> mode"), feel free to add to the page.

Best Regards
Lars
