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.

Previously, gnulib required timeval's tv_sec to be the same size as time_t. But now, it requires only that tv_sec be big enough to hold a time_t. This patch was needed for Emacs. Without the patch, gnulib replaced struct timeval on OpenBSD, and this messed up utimens.c, and Emacs wouldn't build. Alternatively, gnulib could substitute its own struct timeval for the system's, wrapping every struct timeval-using function (gettimeofday, futimesat, futimes, lutimes, etc. That'd be more work, though. And it would introduce some performance issues with gettimeofday, which is supposed to be fast. I've been trying to get away from using struct timeval, and to use the higher-resolution struct timespec instead, so messing with these obsolescent interfaces has been lower priority for me. But if someone wants to take the more-ambitious approach that'd be fine, I expect. For this particular case, though, how about if we avoid the problem entirely? libvirt doesn't need to use struct timeval here at all. It makes libvirt smaller and probably faster, and it ports to OpenBSD without messing with gnulib. |

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.
