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.

https://bugzilla.redhat.com/show_bug.cgi?id=1158034 If we're expecting to create a file somewhere and that fails for some reason during qemuOpenFileAs, then we unlink the path we're attempting to create leaving no way to determine what the "existing" privileges, protections, or labels are that caused the failure (open, change owner and group, change mode, etc.). Furthermore, if we fall into the path where we'll be opening / creating the file using VIR_FILE_OPEN_FORK, we need to first unlink/delete the file we created in the first path; otherwise, the attempt by the child process to open as some specific user:group may fail because the file was already created using nfsnobody:nfsnobody. Again, if we didn't create the file we don't want to blindly delete what already exists. Thus, a second reason for the original check to set need_unlink to false when we find the file with CREAT set, but already existing. Signed-off-by: John Ferlan <jferlan@redhat.com> |

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.
