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.
While reviewing how storage driver used ObjListPtr's for reference in some recent secret driver patches to use the same mechanism, I came across an instance where the wrong API was called for error paths after successfully allocating the storage pool pointer and inserting into the driver pool list. The path is after virStoragePoolObjAssignDef succeeds - the 'def' passed in is assigned to pool->def (or newDef) so it shouldn't be the only thing deleted. The pool is now part of driver->pools.objs, so it would need to be removed (as happens in the storagePoolCreateXML error paths). Rather than calling virStoragePoolDefFree to free the def which is now assigned to the pool, call virStoragePoolObjRemove to ensure the pool element is removed from the driver list and that anything stored in pool is properly handled by virStoragePoolObjFree including the call to virStoragePoolDefFree for the pool->{def|newDef} element. |

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.
