Previous patch of this series proposed a fix to virDirCreate, so that parent process reports an error if child process failed its task. However our logic still permits the child to exit with negative errno followed by a check of the status on the parent side using WEXITSTATUS which, being POSIX compliant, takes the lower 8 bits of the exit code and returns is to the caller. However, by taking 8 bits from a negative exit code (two's complement) the status value we read and append to stream is '2^8 - abs(original exit code)' which doesn't quite reflect the real cause when compared to the meaning of errno values.
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.
