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=1233003 Commit id 'fdda3760' only managed a symptom where it was possible to create a file in a pool without libvirt's knowledge, so it was reverted. The real fix is to have all the createVol API's which actually create a volume (disk, logical, zfs) and the buildVol API's which handle the real creation of some volume file (fs, rbd, sheepdog) manage deleting any volume which they create when there is some sort of error in processing the volume. This way the onus isn't left up to the storage_driver to determine whether the buildVol failure was due to some failure as a result of adjustments made to the volume after creation such as getting sizes, changing ownership, changing volume protections, etc. or simple a failure in creation. Without needing to consider that the volume has to be removed, the buildVol failure path only needs to remove the volume from the pool. This way if a creation failed due to duplicate name, libvirt wouldn't remove a volume that it didn't create in the pool target. |

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.
