Nehal J. Wani reported on IRC a rather interesting build failure: In file included from util/virnetdevbridge.c:53:0: /usr/include/linux/in6.h:30:8: error: redefinition of 'struct in6_addr' struct in6_addr { ^ I traced it to the fact that he ran 'git pull; make check' across commit e62e0094. What happened is that the configure changes result in a new variable that was set to be defined on his system, but config.h was not regenerated to contain the value of that variable. Running 'make' instead of 'make check' cleaned up the problem. A bit more investigation, and I see that in Makefile.am, automake sticks rules that rebuild config.h as part of 'make all', and that we also had a dependency 'check-local: all'; BUT the rule for check-local is run only at the point when the top-level directory is visited. Automake documents that SUBDIRS should contain an explicit '.' at the point the top-level should be visited (defaulting to last, if it doesn't appear). Sure enough, with this patch, 'make check' now does the top-level 'all' rules, which regenerates 'config.h' BEFORE compiling any code that might depend on changed content of that file. * Makefile.am (SUBDIRS): Put '.' first, not last.

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed. Daniel Veillard <veillard@redhat.com>
Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
