Hello this is the third report regarding my project. As usual, quick
summary first. From my last report I have progressed much little than I
would like but, as stated previously also, I'm finishing semester
and between exams and projects it takes almost all my time. However, I'm
free of academic duties next week and I'll double the speed on the project.
What was done so far
--------------------
- Started working on the modifications to the Eucalyptus code, as
expected.
- I've almost complete the code for the Libvirt's XML Domain
definition. I've abstracted the wrapper in order to support a broader
number of arches. Previously it was tailored for supporting x86/amd64
based machines. The idea is to have a list of supported arches and
generate the XML file according that. For ARM some parameters and
elements are different than for the others. This would allow for
people to support another architectures, given they are well supported
by KVM-Qemu.
- Started working on changes to util/data.c to make sure the correct
parameters are being passed to the XML generator and to libvirt kvm
calls.
- Define and start to setup the testing / demo environment. Basically
involves having one machine to run KVM as hypervisor so the Eucalyptus
handler uses it to run ARM kvm-qemu images.
- Over this weekend I'll be publising the code changes on my
website. Steffen suggested to create some docs regarding the progress
too. I'll do that once I feel I'm on track again for my current
pending work, that's coding.
What I'll be working over the next two weeks
--------------------------------------------
- My primary goal is to catch up on the work pace and finish the neccesary
code for Eucalyptus to support ARM images. This means to finish
modifications to:
- node/handlers_kvm.c - handling nc creation. Little changes are need
here from what I've indentified already.
- util/data.{c,h} - handling instance creation. This is the part where
most of the work shall be done. I've started to work here already.
- Test the code I've complete already and send the patches to the teams
involved. To date I'm still working on a local environment, because no
usable patches have been generated already, just little pieces here
and there.
- Since this is a sort of gluing project, that is code here and there
and make it work together. I'm in the process of finding a machine to
be able to test parts of it once they are complete. I'm still
contacting people to get such machine, in anycase I gues I can manage
to get one myself. I can't use my current machine since it involves
reinstalling and working at the OS level.
- For the project's "demo" I'll use both machines, one as the front-end
and the kvm one for NCs (nodes). That's the goal.
What is required after that
---------------------------
- I'd like to release a package that includes my changes, so it can be
installed either from official packages or my own packages, this
involves:
- Updating the packaging bits to the pkg-Eucalyptus repo.
- Talking to upstream about it.
- Write the reference Steffen suggested.
I believe that I can finish the first part in one week, because of the
work I've done in the past weeks to understand the Eucalyptus code. I'm
also will be talking more to the Eucalyptus team and also to the
maintainers about such changes.
I guess that's all for now.
Best regards,
Rudy
