[libvirt] [RFC PATCHv2 0/5] Smartcard support
by Eric Blake
Posting now, even though the patch series is not quite polished
(still lacking a final test), in order to start the review
cycle.
Eric Blake (5):
domain_conf: split source data out from ChrDef
qemu: move monitor device out of domain_conf common code
smartcard: add XML support for <smartcard> device
smartcard: add domain conf support
WIP: smartcard: turn on qemu support

[libvirt] [PATCH v2] qemu: Warning prompt if invalid dump image format specified
by Osier Yang
"getCompressionType" trys to throw error when invalid dump image
format is specified, or the compression program for the specified
image format is not available, but at the same time, it returns
enum qemud_save_formats, as a result, upper function will think
it was successful, and disgard to check the error.
Change "qemuReportError" into "VIR_WARN" instead to let the user
known what happened.
v1 patch is here:
http://www.redhat.com/archives/libvir-list/2011-January/msg00715.html
As it reverted b6f13bb7002da76db15242e1d996e8a6222a754, and it was
intentionally to chose the behavior of falling back to raw if the
compression type is invalid, so simply use "VIR_WARN" to fix the
problem.

[libvirt] Domain callback, the new way
by arnaud.champion＠devatom.fr
?Hi,
I'm working on c# bindings, on domain callback. I have successfully binded the old way to manage callbacks via the old virConnectDomainEventRegister function. Now I'm trying to work with the new API contract with virConnectDomainEventRegisterAny... I'm looking for a sample (in C for exemple) to see how using these functions, can anyone can explain me how this work ?
Regards,
Arnaud

[libvirt] [PATCH 1/1] Do not use virtio-serial port 0 for generic ports
by David Allan
Per the discussion in:
https://bugzilla.redhat.com/show_bug.cgi?id=670394
The port numbering should start from 1, not 0. We assign maxport + 1,
so start maxport at 0.

[libvirt] [PATCH] Imprint all logs with version + package build information
by Daniel P. Berrange
The logging functions are enhanced so that immediately prior to
the first log message being printed to any output channel, the
libvirt package version will be printed.
eg
$ LIBVIRT_DEBUG=1 virsh
18:13:28.013: 17536: info : libvirt version: 0.8.7
18:13:28.013: 17536: debug : virInitialize:361 : register drivers
...
The 'configure' script gains a '--with-package-string' argument
to allow distros to append a custom string with package specific
data.
The RPM specfile is modified so that it appends the RPM version,
the build host, the build date and the packager name.
eg
$ LIBVIRT_DEBUG=1 virsh
18:14:52.086: 17551: info : libvirt version: 0.8.7, package: 1.fc13 (Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10)
18:14:52.086: 17551: debug : virInitialize:361 : register drivers
Thus when distro packagers receive bug reports they can clearly
see what version was in use, even if the bug reporter mistakenly
or intentionally lies about version/builds
* src/util/logging.c: Output version data prior to first log message
* libvirt.spec.in: Include RPM release, date, hostname & packager
* configure.ac: Add --with-package-string arg

[libvirt] [PATCH] Remove double close of qemu monitor
by Daniel P. Berrange
When qemuMonitorSetCapabilities() fails, there is no need to
call qemuMonitorClose(), because the caller will already see
the error code and tear down the entire VM. The extra call to
qemuMonitorClose resulted in a double-free due to it removing
a ref count prematurely.

[libvirt] beginner's project
by Eric Blake
This idea sprang from an IRC conversation, but I don't have time to do
it myself at the moment. If you're looking for a great way to help
development, it would be nice to teach
tests/testutils.c:virtTestLoadFile
how to read a file with backslash-newline pairs and flatten those into a
single line.
Then rewrite all the tests/*data/*.args files to use line continuations,
rather than being monstrous 1000-character lines.
That way, git send-email will quit griping about the inability to send
patches to those files.
