+       <description>
+         NVDIMM is new type of memory introduced into QEMU 2.6. The idea is
+         that we have a Non-Volatile memory module that keeps the data
+         persistent across domain reboots and offers much faster data accesses
+         without causing VMEXITs. However, due to a bug in QEMU, this feature
+         is not enabled for QEMUs older than 2.9.0.

lowercase non-volatile

I don't see what this has to do with VMEXITs, but other than that, ACK.
