https://bugzilla.redhat.com/show_bug.cgi?id=1247987 Calculation of the extended and logical partition values for the disk pool is complex. As the bz points out an extended partition should have it's allocation initialized to 0 (zero) and keep the capacity as the size dictated by the extents read. Then for each logical partition found, adjust the allocation of the extended partition. Finally, previous logic tried to avoid recalculating things if a logical partition was deleted; however, since we now have special logic to handle the allocation of the extended partition, just make life easier by reading the partition table again - rather than doing the reverse adjustment.

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.
