To compile the IVSHMEM library,\n-    one has to either use one of the provided IVSHMEM targets\n-    (for example, x86_64-ivshmem-linuxapp-gcc),\n-    or set CONFIG_RTE_LIBRTE_IVSHMEM to \"y\" in the build configuration.\n-\n-*   Set up hugepage memory on the virtual machine.\n-\n-    The guest applications run as regular DPDK (primary) processes and thus need their own hugepage memory set up inside the VM.\n-    The process is identical to the one described in the *DPDK Getting Started Guide*.\n-\n-Best Practices for Writing IVSHMEM Applications\n------------------------------------------------\n-\n-When considering the use of IVSHMEM for sharing memory, security implications need to be carefully evaluated.\n-IVSHMEM is not suitable for untrusted guests, as IVSHMEM is essentially a window into the host process memory.\n-This also has implications for the multiple VM scenarios.\n-While the IVSHMEM library tries to share as little memory as possible,\n-it is quite probable that data designated for one VM might also be present in an IVSMHMEM device designated for another VM.\n-Consequently, any shared memory corruption will affect both host and all VMs sharing that particular memory.\n-\n-IVSHMEM applications essentially behave like multi-process applications,\n-so it is important to implement access serialization to data and thread safety.\n-DPDK ring structures are already thread-safe, however,\n-any custom data structures that the user might need would have to be thread-safe also.\n-\n-Similar to regular DPDK multi-process applications,\n-it is not recommended to use function pointers as functions might have different memory addresses in different processes.\n-\n-It is best to avoid freeing the rte_mbuf structure on a different machine from where it was allocated,\n-that is, if the mbuf was allocated on the host, the host should free it.\n-Consequently, any packet transmission and reception should also happen on the same machine (whether virtual or physical).\n-Failing to do so may lead to data corruption in the mempool cache.\n-\n-Despite the IVSHMEM mechanism being zero-copy and having good performance,\n-it is still desirable to do processing in batches and follow other procedures described in\n-:ref:`Performance Optimization <Performance_Optimization>`.\n-\n-Best Practices for Running IVSHMEM Applications\n------------------------------------------------\n-\n-For performance reasons,\n-it is best to pin host processes and QEMU processes to different cores so that they do not interfere with each other.\n-If NUMA support is enabled, it is also desirable to keep host process' hugepage memory and QEMU process on the same NUMA node.\n-\n-For the best performance across all NUMA nodes, each QEMU core should be pinned to host CPU core on the appropriate NUMA node.\n-QEMU's virtual NUMA nodes should also be set up to correspond to physical NUMA nodes.\n-More on how to set up DPDK and QEMU NUMA support can be found in *DPDK Getting Started Guide* and\n-`QEMU documentation <http://qemu.weilnetz.de/qemu-doc.html>`_ respectively.\n-A script called cpu_layout.py is provided with the DPDK package (in the tools directory)\n-that can be used to identify which CPU cores correspond to which NUMA node.\n-\n-The QEMU IVSHMEM command line creation should be considered the last step before starting the virtual machine.\n-Currently, there is no hot plug support for QEMU IVSHMEM devices,\n-so one cannot add additional memory to an IVSHMEM device once it has been created.\n-Therefore, the correct sequence to run an IVSHMEM application is to run host application first,\n-obtain the command lines for each IVSHMEM device and then run all QEMU instances with guest applications afterwards.\n-\n-It is important to note that once QEMU is started, it holds on to the hugepages it uses for IVSHMEM devices.\n-As a result, if the user wishes to shut down or restart the IVSHMEM host application,\n-it is not enough to simply shut the application down.\n-The virtual machine must also be shut down (if not, it will hold onto outdated host data).\ndiff --git a/doc/guides/prog_guide/source_org.rst b/doc/guides/prog_guide/source_org.rst\nindex 0c06d47..d9c140f 100644\n--- a/doc/guides/prog_guide/source_org.rst\n+++ b/doc/guides/prog_guide/source_org.rst\n@@ -70,7 +70,6 @@ The lib directory contains::\n     +-- librte_ether        #
