Currently, the hook function in virFileOperation is extremely limited: it must be async-signal-safe, and cannot modify any memory in the parent process. It is much handier to return a valid fd and operate on it in the parent than to deal with hook restrictions. * src/util/util.h (VIR_FILE_OP_RETURN_FD): New flag. * src/util/util.c (virFileOperationNoFork, virFileOperation): Honor new flag.
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.
