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.

In order to choose whether to use O_DIRECT when saving a domain image to a file, we need a new flag. But virDomainSave was implemented before our policy of all new APIs having a flag argument. Likewise for virDomainRestore when restoring from a file. The new flag name is chosen as CACHE_BYPASS so as not to preclude a future solution that uses posix_fadvise once the Linux kernel has a smarter implementation of that interface. * include/libvirt/libvirt.h.in (virDomainCreateFlags) (virDomainCoreDumpFlags): Add a flag. (virDomainSaveFlags, virDomainRestoreFlags): New prototypes. * src/libvirt.c (virDomainSaveFlags, virDomainRestoreFlags): New API. * src/libvirt_public.syms: Export them. * src/driver.h (virDrvDomainSaveFlags, virDrvDomainRestoreFlags): New driver callbacks. |

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.
