https://bugzilla.redhat.com/show_bug.cgi?id=1233129 The virStoragePoolObjSourceFindDuplicate logic used by PoolCreateXML and PoolDefineXML avoids comparing the new definition against "other" pool types. This can cause unexpected corruption if two different pool source types used the same source device path. For example, a 'disk' pool using source type device=/dev/sdc could be unwittingly overwritten by using /dev/sdc for a 'logical' pool which also uses the source device path. So rather than blindly ignoring those checks when def->type != pool->def->type - have the pool->def->type switch logic handle the check for which def->type's should be checked.
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.
