[libvirt] [PATCH 0/2] RFC: New libssh transport
by Pino Toscano
Hi,
this series introduces a new libssh transport in libvirt, based on the
libssh C library. This library supports what libssh2 does, and more:
- easier API for known_hosts handling (there's a ticket upstream to
request extensions for it, but what is implemented now works well)
- potential GSSAPI authentication (not enabled yet because of a libssh
bug [1]
- easier API for ssh-agent support
TODO:
- implement the keyboard-interactive authentication method
- more testing than my own
The implementation for the new transport is based on the libssh2 one,
hence it shares origin and style.
[1] https://red.libssh.org/issues/242
Thanks,

Well, I have to admin that this^^ is a fair argument because there are 3
different spots where the function can fail, not that the caller could not
check result for NULL but the fact that a function touched caller's argument
and then failed would be just weird. So, yeah, good point.

Exactly, if a caller wanted to just compare 2 values - old and new one - they
would use a temporary variable, that would IMHO be expected correct behaviour.
Anyway, it's irrelevant now that I agree with your point above.

Yeah, since the patch is going to be relatively beefy, this change will blend
in fairly easily, so go ahead, ACK.
Erik
NOTE: I've recently switched to mutt and it's still quite new, so I forgot to
hit 'g' for group reply, therefore most of this conversation 'officially' never
happened, so CC'ng libvir-list at least for the last bit, I suppose the whole
'thread' is going to look odd, sigh....

[libvirt] [PATCH 0/4] vbox: address thread-safety issues.
by Dawid Zamirski
This patch series solves (at least in my testing) vbox driver
thread-safety issues that were also outlined on libvirt-users ML [1]
and I was affected with. Those patches try to follow the suggestions
made Matthias' [2] in that thread as close as possible. Here's where
my patch differs from that suggesions:
* vboxGlobalData - still needs to keep reference to ISession and
IVirutalBox session because it's apparently not possible to have
multiple instances created/destroyed safely with pfnComInitialize
and pfnComUninitalize calls on per-connection basis.
* as such vboxPrivate (the new struct introduced here) also has
references to ISession and IVirutalBox (which are just referenes to
the ones from the global) mainly to immitate ISession instance
per-connection. Apparently newer VBOX SDKs introduced
pfnClinetInitialize that can allegedly create multiple ISessions and
we might want to take advantage of that in the future hopefully
without making additional changes allover the driver code that this
patch did.
The gist of the change is in patch 3 and it also contains more
in-depth explanation on how the issue is being resolved. Also, please
note that patch 4 should be squashed into 3 as it was kept separate
only for code-review purposes and 3rd patch won't compile without 4
applied on top.

[2] https://www.redhat.com/archives/libvirt-users/2012-April/msg00125.htmlgq
Dawid Zamirski (4):
vbox: add vboxPrivate struct.
vbox: replace vboxGlobalData with vboxPrivate.
vbox: change API (un)initialization logic.
vbox: update rest of the code to for prior changes.

[libvirt] [PATCH] virLogDefineOutputs: Fix build without syslog.h
by Michal Privoznik
Not every system out there has syslog, that's why we check for it
in our configure script. However, in 640b58abdf while fixing
another issue, some variables and functions are called that are
defined only when syslog.h is present. But these function
calls/variables were not guarded by #ifdef-s.

[libvirt] libvirt API / balloon last-update
by Marko Myllynen
Hi,
I see that recently the last-update field has been added to the balloon
statistics, this is how it looks like from Python:
[(<libvirt.virDomain object at 0x7fb45b7faa50>, {'balloon.rss': 960048L,
'balloon.swap_in': 0L, 'balloon.usable': 1676424L, 'balloon.unused':
1376188L, 'balloon.major_fault': 816L, 'balloon.swap_out': 0L,
'balloon.current': 2097152L, 'balloon.maximum': 2097152L,
'balloon.available': 2048364L, 'balloon.minor_fault': 460160L,
'balloon.last-update': 1476213030L})]
As you can see, there's an inconsistency as all the other members use
underscore (_), not dash (-). This actually matters with the PCP plugin
since PCP metric names can contain _ but not -.
Now that last-update is part of the API in 2.3 I guess it's too late to
change this but it would nice if in the future the member names could be
kept consistent and underscore used for new members, as it has been so far.
Thanks,
