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.

By probing for qemu machine types, we increased the time of a GetCapabilities call from 100us to a whopping 60ms. This patch takes the approach of only probing for machine types when the mtime of the emulator binary changed since the last time the capabilities were generated. * src/capabilities.h: cache the emulator binary mtime * src/qemu_conf.c: add qemudGetOldMachines() to copy the machine types from the old caps struct if the mtime for the binary hasn't changed * src/qemu_conf.h, src/qemu_driver.c: pass the old caps pointer to qemudCapsInit() |

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.
