+    Adding two parameters to manage vPMEM [0] configuration parameters.
+    `NovaPMEMMappings` parameter set Nova's configuration option
+    `pmem_namespaces` that reflects mappings between vPMEM
+    and physical PMEM namespaces. `NovaPMEMNamespaces` creates
+    and manages physical backend PMEM namespaces which win
+    be used as backend for vPMEM.
+    `NovaPMEMMappings` example: 6GB:ns0|ns1|ns2,LARGE:ns3
+    will expose namespaces ns0, ns1, ns2 using label `6GB`
+    and namespace ns3 using label `LARGE`.
+    `NovaPMEMNamespaces` example: 100G:ns0|14096M:ns1
+    will create two namespaces: ns0 - size 100G, ns1 - size 14096M.
