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.

This eliminates the warning message reported in: https://bugzilla.redhat.com/show_bug.cgi?id=624447 It was caused by a failure to open an image file that is not accessible by root (the uid libvirtd is running as) because it's on a root-squash NFS share, owned by a different user, with permissions of 660 (or maybe 600). The solution is to use virFileOpenAs() rather than open(). The codepath that generates the error is during qemuSetupDiskCGroup(), but the actual open() is in a lower-level generic function called from many places (virDomainDiskDefForeachPath), so some other pieces of the code were touched just to add dummy (or possibly useful) uid and gid arguments. Eliminating this warning message has the nice side effect that the requested operation may even succeed (which in this case isn't necessary, but shouldn't hurt anything either). |

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.
