[PATCH 0/6] Coverity cleanups
by John Ferlan
A recent Coverity version update discovered some existing issues (and some
benign cases). This patch set cleans them all up.

How LIBVIRT-CIM actually works
by Bouabid Mohamed Amine
Hello,
I am a CIM developer and i am interested in LIBVIRT-CIM as a foundation for
a futur work, so i have some questions about its design:
How the VMs' life cycle methods are mapped with libvirt API? i mean the
methods of the class CIM_VirtualSystemManagementService (DefineSystem,
DestroySystem, ModifyResourceSettings, ModifySystemSettings,
RemoveResourceSettings)
What is the relation between the command wirsh and its XML description
with the classes CIM_VirtualSystemSettingData,
CIM_ResourceAllocationSettingData ?
Is the libvirt-cim provider invoking the virsh command ?
Thanks in advance

libvirt-cim compil errors
by Bouabid Mohamed Amine
Hello,
I have compile errors when installing libvirt-cim from sources on UBUNTU
13.10 (amd-64 platform)
I am using openpegasus as cimom, and i installed libcmpiutil successfully
Bellow are the errors i get after make command (i followed instructions on
the website http://wiki.libvirt.org/page/Libvirt-cim_setup)
.....

the following commands do not working:

$ hg clone http://libvirt.org/hg/libvirt-cim/
the server says :

[PATCH] spec: Fix docs/*.html packaging issue
by John Ferlan
Using a more recent rpmbuild on f20, I found that the 'make rpm' was failing:
Installed (but unpackaged) file(s) found:
/usr/share/doc/libvirt-cim-0.6.3/html/architecture.html
/usr/share/doc/libvirt-cim-0.6.3/html/downloads.html
/usr/share/doc/libvirt-cim-0.6.3/html/index.html

/usr/share/doc/libvirt-cim-0.6.3/html/platforms.html
/usr/share/doc/libvirt-cim-0.6.3/html/schema.html
make: *** [rpm] Error 1
After a bit of research - I found the following page that describes a
workaround to add "%define _unpackaged_files_terminate_build 0" to the
spec file:
http://www.oldrpm.org/hintskinks/unpackaged/
However, figuring that wasn't a great solution - I found a libvirt change
that provided a way to work around what was being seen, see:
http://www.redhat.com/archives/libvir-list/2013-November/msg00441.html
It seems as though having that %doc doc/*.html is not proper any more.
With this change I can once again build RPM packages

[PATCH] VSMS: fv_vssd_to_domain() resolve Coverity error
by John Ferlan
Coverity discovered that the free(domain->os_info.fv.arch) and then
usage later on during get_default_machine() and get_default_emulator()
calls could result in using free()'d memory.
If the 'cu_get_str_prop() failed or capsinfo == NULL, then the fv.arch
wouldn't necessarily be strdup()'d.
Passing a NULL os_info.fv_arch into the get*() API's is fine since
they'll call findDomainInfo() which can handle a NULL arch value.
Also added an initialization of val just to be safe. I don't think it's
necessary though.
---
NOTE:
I found this during a Coverity run applying the endianness patches. For
some reason Coverity "woke up" and saw this even though it hasn't found
this issue in a couple months of runs since the changes to this module
were made. See commit id '117dabb9'.
