+  * Remove NVDIMM auto-alignment for pSeries Guests

+    NVDIMM support for pSeries guests. The idea was to relieve the user

+    size the guest is using. To promote consistency between domain XML
+    and the guest, unaligned NVDIMM sizes for pSeries guests will now be
+    forbid and no size auto-alignment will be made. Instead, libvirt will

s/forbid/forbidden/

+    suggest an aligned round up size for the user.
