https://bugzilla.redhat.com/show_bug.cgi?id=1159180 The virStoragePoolSourceFindDuplicate only checks the incoming definition against the same type of pool as the def; however, for "scsi_host" and "fc_host" adapter pools, it's possible that either some pool "scsi_host" adapter definition is already using the scsi_hostN that the "fc_host" adapter definition wants to use or some "fc_host" pool adapter definition is using a vHBA scsi_hostN or parent scsi_hostN that an incoming "scsi_host" definition is trying to use. This patch adds the mismatched type checks and adds extraneous comments to describe what each check is determining. This patch also modifies the documentation to be describe what scsi_hostN devices a "scsi_host" source adapter should use and which to avoid. It also updates the parent definition to specifically call out that for mixed environments it's better to define which parent to use so that the duplicate pool checks can be done properly.
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.
