[libvirt] [PATCH] ESX: Fix memory leak in list handling functions.
by Matthias Bolte
If an error occurs between the allocation of an item and appending it
to the list, the item leaks. Free such orphaned items in error cases.

[libvirt] [PATCH 0/4] Support for SPICE graphics
by Daniel P. Berrange
This series of patches adds minimal support for SPICE graphics
which is newly introduced in RHEL-5.4's fork of KVM. Since this
is not yet merged in upstream QEMU/KVM, I'm not proposing to merge
all these patches. The two XML schema patches are straightforward
to merge.
The two implementation ones are RHEL5 specific and I want to
avoid declaring them supported until we have a sign of what the
upstream merge will look like, since previous attempst to support
KVM args prior to QEMU acceptance have been very painful long
term.

[libvirt] [PATCH] libvirt-devel should only require libvirt-client
by Mark McLoughlin
There's a long known issue where if you install libvirt in a guest,
the default virtual network will conflict with the default virtual
network in the host.
That's one of the reasons we have the libvirt-client RPM - it allows
you to install the client library without having the host side
installed.
Rich Jones points out that if you install libvirt-devel in a guest,
then you get libvirtd installed and the network conflict:
https://bugzilla.redhat.com/531200
libvirt-devel should only require libvirt-client - e.g. nothing in
the devel package pertains to anything in the libvirt RPM. The Fedora
packaging guidelines say:
https://fedoraproject.org/wiki/Packaging/Guidelines#Devel_Packages
Devel packages must require the base package using a fully versioned
dependency ...
But for all intents and purposes, libvirt-client is our base RPM.
* libvirt.spec.in: make libvirt-devel require libvirt-client

[libvirt] [PATCH 0/4] test: Support virStorageFindPoolSources
by Cole Robinson
The following series refactors the storage pool parsing code to better
facilitate FindPoolSources (both for the test driver, and future pool backend
implementations). The last patch implements a FindPoolSources for the test
driver, with hardcoded results for test:///default.
Thanks,
Cole
Cole Robinson (4):
storage: Break out pool source parsing to a separate function.
storage: Break out function to add pool source to a SourceList.
storage: Add ParseSourceString function for use with FindPoolSources.
test: Support virStorageFindPoolSources
