[libvirt] [PATCH 1/2] util: introduce virDirRead wrapper for readdir
by Natanael Copa
Introduce a wrapper for readdir. This helps us make sure that we always
set errno before calling readdir and it will make sure errors are
properly logged.

Re: [libvirt] libvirt Hyper-v 2012 r2 fix
by vikhyath reddy
Bringing the discussion back online...
Okay so figured out what was going on (to see what the actual error was,
please read the latest email in the conversation). Classes in
hyperv/hyperv_wmi_generator.input
a) Msvm_MemorySettingData
b) Msvm_ProcessorSettingData
c) Msvm_VirtualSystemSettingData
Have been upgraded to the definitions found at the new v2 doc
http://msdn.microsoft.com/en-us/library/hh850176(v=vs.85).aspx,
I put in this note at the beginning of the
hyperv/hyperv_wmi_generator.input file.
With these changes and a few other minor ones, I can confirm that the
functionality mimics the hyperv 2008 version. That is, we get the same
functionality (supported vs non-supported drivers).
However, this might also mean the end of support of Hyper-V 2008 if it is
just a replace of the existing classes. What do you guys think? Should we
continue to support 2008 (~6 years old) OR is it OK to assume that Hyperv-V
2012 will be the default standard moving forward.
Thanks,
Vik.

[libvirt] [PATCHv2 0/9] RelaxNG improvements for virStorageSource
by Eric Blake
changes since v1:
ack'd patch pushed
new patches 2-4 are a better rewrite of old patch 3/6
new patches 8 and 9
patch 9 is incomplete - I know where I want to be headed, but
changing 400+ tests is taking a while. I tried:
$ git grep -l '<driver.*type=' tests/*data/ | \
xargs sed '
/<driver .*type=\(\(.\)[a-zA-Z0-9]*\2\)/ h;
/<source /{
x;
s/<driver.*type=\(\(.\)[a-zA-Z0-9]*\2\).*>/<format type=\1>/;
G;
}'
as a way to automate the majority of the tedium, with some limited
success (it has false positives in the lxc <filesystem> elements,
when we really only want to affect <disk> elements>), but have not
completed the efforts. I'm posting the patches now, in the hopes
that 1-8 can be approved, and 9 picked up by someone else if I'm
unresponsive for a while (I'll be offline for much of this week due
to the birth of my fourth child).
Eric Blake (9):
conf: better <disk> interleaving in schema
conf: move storage formats to common RNG file
conf: restrict external snapshots to backing store formats
conf: set up for per-grammar overrides in schemas
conf: split <disk> schema into more pieces
conf: move storage source details to common RNG file
conf: move <auth> and <encryption> to disk source
conf: fix omission of <driver> in domain dumpxml
RFC: conf: introduce <format> as synonym of <driver type=...>

[libvirt] Fwd: Start contributing with Libvirt (Finding a mentor or helpful tips)
by Julio Faracco
Hi everybody!
I sent an e-mail to Daniel asking about contributing to the libvirt
community for free.
So, I copied the e-mail to the libvirt mailing list as Daniel suggested me.
If anyone can help me I'd be pleased.
Thanks very much!

Subject: Start contributing with Libvirt (Finding a mentor or helpful tips)
To: dan(a)berrange.com
Hi Daniel.
My name is Julio and I sent this e-mail because I would like to contribute
with libvirt. Moreover, I follow the libvirt mailing list for a long time
and have read the ideas page of libvirt, qemu and KVM of Google Summer of
Code program. I thought the ideas very interesting but I didn't have time
to propose my ideais or submit a patch. But I don't know a good way to
start doing that.
I want to contribute with libvirt for free (not like GSoC who pays a
paycheck for it). I think that contributing with a project like libvirt
enhances some of my programming skills. Today I work with Linux
distribution management and not with programing itself. However, I'm
finding some troubles to start. For example:
- Can I fix a random open bug?
- How to understand which bug can be easier to solve?
- How to follow the conversation of the mailing list? Sometimes I feel so
lost.
I was looking for a mentor (if you know someone who could help me) or a
person who can help me to follow the right way to start it.
Thanks very much.

[libvirt] [PATCH v2] virsh: Separate 'create'/'modify' message for secret-define
by Li Yang
The current message of secret-define always be:
Secret 09a9736f-eedb-449c-9983-80d0ab67393f created
even you just modify the secret, perhaps this may puzzle uses. Now
this patch make the modify action output message like this:
Secret f2d1bafc-ac58-4a47-93e4-47723686fef5 modified

Oh, yes, you are right, I didn't notice that. I will try another way to cover this situation.
If I cannot find an easy way to solve this problem, I think we'd better leave it at that,
Modify "created" to "defined" seems not enough useful for uses...
After all, secret-undefine command's output is "Secret *** deleted", it's correspond
to secret-define command's output "Secret *** created".
