[libvirt] [PATCH][libvirt-sandbox] configure: Require higher version of glib
by Michal Privoznik
Since commit cfd4460b we must require glib-2.32.0 at least
because we are using g_value_set_schar which was introduced
in that release.

[libvirt] [PATCH 1/5] S390: Override QEMU_CAPS_NO_ACPI for s390x
by Viktor Mihajlovski
Starting a KVM guest on s390 fails immediately. This is because
"qemu --help" reports -no-acpi even for the s390(x) architecture but
-no-acpi isn't supported there.
Workaround is to remove QEMU_CAPS_NO_ACPI from the capability set
after the version/capability extraction.

[libvirt] [PATCH] Add support for shared sanlock leases
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
A sanlock lease can be marked as shared (rather
than exclusive) using SANLK_RES_SHARED flag. This
adds support for that flag and ensures that in auto
disk mode, any shared disks use shared leases. This
also makes any read-only disks be completely
ignored.
These changes remove the need for the option
ignore_readonly_and_shared_disks
so that is removed

[libvirt] [PATCH] winsock2.h must always be included before windows.h
by Daniel P. Berrange
From: "Daniel P. Berrange" <berrange(a)redhat.com>
Some GNULIB headers (eg unistd.h) will often need to include
winsock2.h for various symbols. There is a rule that winsock2.h
must be included before windows.h. This means that any file
which does
#ifdef WIN32
#include <windows.h>
#endif
#include <unistd.h>
is potentially broken. A simple rule is that /all/ includes of
windows.h must be matched with a preceeding include of winsock2.h
regardless of whether unistd.h is used currently

KVM is an industry leading open source hypervisor that provides an ideal
platform for datacenter virtualization, virtual desktop infrastructure,
and cloud computing. Once again, it's time to bring together the
community of developers and users that define the KVM ecosystem for
our annual technical conference. We will discuss the current state of
affairs and plan for the future of KVM, its surrounding infrastructure,
and management tools. We are also excited to announce the oVirt Workshop
will run in parallel with the KVM Forum, bringing in a community focused
on enterprise datacenter virtualization management built on KVM. So mark
your calendar and join us in advancing KVM.
Once again we are colocated with The Linux Foundation's LinuxCon,
Based on feedback from last year, this time it's LinuxCon Europe!
Conference: November 7 - 9, 2012
