52 * security updates applied
54 * `vloop-vnf-ubuntu-14.04_20160804`_
56 * Linux kernel 4.4.0 installed
57 * libnuma-dev installed
58 * security updates applied
60 * `vloop-vnf-ubuntu-14.04_20160303`_
62 * snmpd service is disabled by default to avoid error messages during VM boot
63 * security updates applied
65 * `vloop-vnf-ubuntu-14.04_20151216`_
67 * version with development tools required for build of DPDK and l2fwd
71 The test suite requires Python 3.3 and relies on a number of other
72 packages. These need to be installed for the test suite to function.
74 Installation of required packages, preparation of Python 3 virtual
75 environment and compilation of OVS, DPDK and QEMU is performed by
76 script **systems/build_base_machine.sh**. It should be executed under
77 user account, which will be used for vsperf execution.
79 **Please Note**: Password-less sudo access must be configured for given
80 user account before script is executed.
82 Execution of installation script:
87 $ ./build_base_machine.sh
89 **Please Note**: you don't need to go into any of the systems subdirectories,
90 simply run the top level **build_base_machine.sh**, your OS will be detected
93 Script **build_base_machine.sh** will install all the vsperf dependencies
94 in terms of system packages, Python 3.x and required Python modules.
95 In case of CentOS 7 or RHEL it will install Python 3.3 from an additional
96 repository provided by Software Collections (`a link`_). Installation script
97 will also use `virtualenv`_ to create a vsperf virtual environment, which is
98 isolated from the default Python environment. This environment will reside in a
99 directory called **vsperfenv** in $HOME.
101 **Please Note**: For RHEL 7.3 Enterprise and CentOS 7.3 OVS Vanilla is not
102 built from upstream source due to kernel incompatibilities. Please see the
103 instructions in the vswitchperf_design document for details on configuring
104 OVS Vanilla for binary package usage.
106 You will need to activate the virtual environment every time you start a
107 new shell session. Its activation is specific to your OS:
114 $ scl enable python33 bash
116 $ source bin/activate
124 $ source bin/activate
130 $ source bin/activate
133 Check what type of shell you are using
140 See what scripts are available in $HOME/vsperfenv/bin
145 activate activate.csh activate.fish activate_this.py
147 source the appropriate script
151 $ source bin/activate.csh
153 Working Behind a Proxy
154 ======================
156 If you're behind a proxy, you'll likely want to configure this before
157 running any of the above. For example:
161 export http_proxy=proxy.mycompany.com:123
162 export https_proxy=proxy.mycompany.com:123

171 Hugepage Configuration
172 ----------------------
174 Systems running vsperf with either dpdk and/or tests with guests must configure
175 hugepage amounts to support running these configurations. It is recommended
176 to configure 1GB hugepages as the pagesize.
178 The amount of hugepages needed depends on your configuration files in vsperf.
179 Each guest image requires 2048 MB by default according to the default settings
180 in the ``04_vnf.conf`` file.
184 GUEST_MEMORY = ['2048']
186 The dpdk startup parameters also require an amount of hugepages depending on
187 your configuration in the ``02_vswitch.conf`` file.
191 VSWITCHD_DPDK_ARGS = ['-c', '0x4', '-n', '4', '--socket-mem 1024,1024']
192 VSWITCHD_DPDK_CONFIG = {
193 'dpdk-init' : 'true',
194 'dpdk-lcore-mask' : '0x4',
195 'dpdk-socket-mem' : '1024,1024',
198 Note: Option VSWITCHD_DPDK_ARGS is used for vswitchd, which supports --dpdk
199 parameter. In recent vswitchd versions, option VSWITCHD_DPDK_CONFIG will be
200 used to configure vswitchd via ovs-vsctl calls.
202 With the --socket-mem argument set to use 1 hugepage on the specified sockets as
203 seen above, the configuration will need 10 hugepages total to run all tests
204 within vsperf if the pagesize is set correctly to 1GB.
206 VSPerf will verify hugepage amounts are free before executing test
207 environments. In case of hugepage amounts not being free, test initialization
208 will fail and testing will stop.
210 **Please Note**: In some instances on a test failure dpdk resources may not
211 release hugepages used in dpdk configuration. It is recommended to configure a
212 few extra hugepages to prevent a false detection by VSPerf that not enough free
213 hugepages are available to execute the test environment. Normally dpdk would use
214 previously allocated hugepages upon initialization.
216 Depending on your OS selection configuration of hugepages may vary. Please refer
217 to your OS documentation to set hugepages correctly. It is recommended to set
218 the required amount of hugepages to be allocated by default on reboots.
220 Information on hugepage requirements for dpdk can be found at
221 http://dpdk.org/doc/guides/linux_gsg/sys_reqs.html
223 You can review your hugepage amounts by executing the following command
227 cat /proc/meminfo | grep Huge
229 If no hugepages are available vsperf will try to automatically allocate some.
230 Allocation is controlled by HUGEPAGE_RAM_ALLOCATION configuration parameter in
231 ``02_vswitch.conf`` file. Default is 2GB, resulting in either 2 1GB hugepages
232 or 1024 2MB hugepages.
