+If you encounter the following error: "before (last 100 chars):
+'-path=/dev/hugepages,share=on: unable to map backing store for
+hugepages: Cannot allocate memory\r\n\r\n" with the PVP deployment
+scenario, check the amount of hugepages on your system:
+
+.. code:: bash
+
+ cat /proc/meminfo | grep HugePages

+By default the vswitchd is launched with 1Gb of memory, to change
+this, modify --socket-mem parameter in conf/02_vswitch.conf to allocate
+an appropriate amount of memory:
+
+.. code:: bash
+
+ VSWITCHD_DPDK_ARGS = ['-c', '0x4', '-n', '4', '--socket-mem 1024,0']
