https://bugzilla.redhat.com/show_bug.cgi?id=1282288 Rather than using just open on the path, allow for the possibility that the path to be opened resides on an NFS root-squash target and was created under a different uid/gid. Without using virFileOpenAs an attempt to get the volume size data may fail if the current user doesn't have permissions to read the volume, such as would be the case if mode wasn't supplied in the volume XML and the default VIR_STORAGE_DEFAULT_VOL_PERM_MODE (e.g. 0600) was used. Under this scenario the owner/group is not root:root, thus this path run under root would fail to open/read the volume. NB: The virFileOpenAs code using OPEN_FORK will only work when the failure is not EACESS/EPERM and the path resolves to a shared file system. |

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.
