If this reminds you of a commit message from around a year ago, it's41c2aa729fand yes, we're dealing with "the same thing" again. Orf309db1f4dand it's similar. There is a logic in place that if there is no real need for memory-backend-file, qemuBuildMemoryBackendStr() returns 0. However that wasn't the case with hugepage backing. The reason for that was that we abused the 'pagesize' variable for storing that information, but we should rather have a separate one that specifies whether we really need the new object for hugepage backing. And that variable should be set only if this particular NUMA cell needs special treatment WRT hugepages.

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.
