 The `tag` needs to be consistent with what has been provided through the
 Cloud Hypervisor command line, which happens to be `myfs` in this example.
 
-The `-o dax` option must be removed in case the shared cache region is not
-enabled from the VMM.
+## DAX feature
 
-The filesystem should be mounted with `dax` by default as it bypasses the guest
-page cache, reducing the footprint on host memory. When running multiple virtual
-machines on the same host, this will let the host deal with page cache, which
-will increase the density of virtual machines which can be launched.
-
-When the filesystem is not mounted with the `dax` option, the guest page cache
-is used, which can result in better performance for the guest's workload at the
-cost of increasing the footprint on host memory.
+Given the DAX feature is not stable yet from a daemon standpoint, it is not
+available in Cloud Hypervisor.
