Currently we try to chown any directory passed to virDirCreate, even if the user didn't request any explicit owner/group via the pool/vol XML. This causes issues with qemu:///session: try to build a pool of a root owned directory like /tmp, and it fails trying to chown the directory to the session user. Instead it should just leave things as they are, unless the user requests changing permissions via the pool XML. Similarly this is annoying if creating a storage pool via system libvirtd of an existing directory in user $HOME, it's now owned by root. The virDirCreate function is pretty convoluted, since it needs to fork off in certain specific cases. Try to document that, to make it clear where exactly we are changing behavior.
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.
