[libvirt] [resend] fix libvirt alignment on arm platforms
by Michele Paolino
With the changes added by the latest commits (e.g.
8a29ffcf9aee45b61a0a12ee45c656cfd52333e8) related to "new events feature
v2",
we are unable to compile libvirt on ARM target (OMAP5).
The error is due to alignment:
conf/domain_event.c: In function 'virDomainEventDispatchDefaultFunc':
conf/domain_event.c:1198:30: error: cast increases required alignment of
target type [-Werror=cast-align]
conf/domain_event.c:1314:34: error: cast increases required alignment of
target type [-Werror=cast-align]
cc1: all warnings being treated as errors
Using ATTRIBUTE_PACKED we force a structure to not follow architecture and
compiler best alignments.

by Martin Kletzander
To see what changed in the kernel, see explanation in PATCH 1/3.
First two patches make proper use of VIR_DOMAIN_MEMORY_PARAM_UNLIMITED,
the third one just fixes a "typo".
Martin Kletzander (3):
cgroups: Redefine what "unlimited" means wrt memory limits
qemu: Report VIR_DOMAIN_MEMORY_PARAM_UNLIMITED properly
qemu: Fix minor inconsistency in error message

[libvirt] [PATCH] Read PCI class from sysfs class file instead of config space.
by Thadeu Lima de Souza Cascardo
When determining if a device is behind a PCI bridge, the PCI device
class is checked by reading the config space. However, there are some
devices which have the wrong class on the config space, but the class is
initialized by Linux correctly as a PCI BRIDGE. This class can be read
by the sysfs file '/sys/bus/pci/devices/xxxx:xx:xx.x/class'.
One example of such bridge is IBM PCI Bridge 1014:03b9, which is
identified as a Host Bridge when reading the config space.

[libvirt] RFC: Changing version number at start of dev cycle instead of end
by Daniel P. Berrange
Currently throughout the dev cycle we stick on the current release
number. The release number in configure.ac is only changed by DV
when he is actually cutting the release.
With the python bindings now being split out, this is causing us
problems. The python code aims to build against any libvirt version
that exists, so for example, the new network events APIs in libvirt
will be included with version 1.2.1. So the python binding does
#if LIBVIR_CHECK_VERSION(1, 2, 1)
static void
libvirt_virConnectNetworkEventFreeFunc(void *opaque)
{
PyObject *pyobj_conn = (PyObject*)opaque;
LIBVIRT_ENSURE_THREAD_STATE;
Py_DECREF(pyobj_conn);
LIBVIRT_RELEASE_THREAD_STATE;
}
...
This works fine if a python release is built against a libvirt
release. It does not work if a python git snapshot is built
against a libvirt git snapshot. This is bad because it prevents
us doing automated builds of GIT.
The solution here is fairly simple. We should increase the version
number in configure.ac at the *start* of each release cycle. This
means that libvirt-python can use the next version number and things
will 'just work'. I don't think this is a burden really - we already
encode the next version number in our source code when tagging new
APIs or driver methods. We're really just bringing autoconf's view
of the version number inline with the rest of the code.
So if no one objects, we should immediately change configure.ac to
be 1.2.1
Regards,
Daniel
