         If set, the speculation controls are managed by the host. This is intended
         for guests which do not set the speculation controls themselves.
+        Note! This has not yet been implemented beyond leaving everything to the host OS.

+      <desc>
+        If set and the host is affected by CVE-2018-3646, flushes the level 1 data
+        cache when the EMT is scheduled to do ring-0 guest execution.  There could
+        be a small performance penalty for certain typs of workloads.
+        For security reasons this setting will be enabled by default.

+    <const name="L1DFlushOnVMEntry"     value="12">
+      <desc>
+        If set and the host is affected by CVE-2018-3646, flushes the level 1 data
+        on every VM entry.  This setting may significantly slow down workloads
+        causing many VM exits, so it is only recommended for situation where there
+        is a real need to be paranoid.
