+ASLR feature causes core dump
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Core dump may occur when we start secondary processes on the vf port.
+Mainstream Linux distributions have the ASLR feature enabled by default,
+and the text segment of the process's memory space is randomized.
+The secondary process calls the function address shared by the primary
+process, resulting in a core dump.
+
+   .. Note::
+
+	  Support for ASLR features varies by distribution. Redhat and
+	  Centos series distributions work fine. Ubuntu distributions
+	  will core dump, other Linux distributions are unknown.
