1 Test Environment\r
2 ================\r
3 \r
4 CSIT functional tests are currently executed in FD.IO VIRL testbed. The physical\r
5 VIRL testbed infrastructure consists of three VIRL hosts:\r
6 \r
7 - All hosts are Cisco UCS C240-M4 (2x Intel(R) Xeon(R) CPU E5-2699 v3 @2.30GHz,\r
8   18c, 512GB RAM)\r
9 - tb4-virl1:\r
10 \r
11   - Status: Production\r
12   - OS: Ubuntu 16.04.2\r
13   - STD server version 0.10.32.16\r
14   - UWM server version 0.10.32.16\r
15 \r
16 - tb4-virl2:\r
17 \r
18   - Status: Production\r
19   - OS: Ubuntu 16.04.2\r
20   - STD server version 0.10.32.16\r
21   - UWM server version 0.10.32.16\r
22 \r
23 - tb4-virl3:\r
24 \r
25   - Status: Production\r
26   - OS: Ubuntu 14.04.3\r
27   - STD server version 0.10.24.7\r
28   - UWM server version 0.10.24.7\r
29 \r
30 Whenever a patch is submitted to gerrit for review, parallel VIRL simulations\r
31 are started to reduce the time of execution of all functional tests. The number\r
32 of parallel VIRL simulations is equal to number of test groups defined by\r
33 TEST_GROUPS variable in csit/bootstrap.sh file. The VIRL host to run VIRL\r
34 simulation is selected based on least load algorithm per VIRL simulation.\r
35 \r
36 Every VIRL simulation uses the same three-node - Traffic Generator (TG node) and\r
37 two Systems Under Test (SUT1 and SUT2) - "double-ring" topology. The appropriate\r
38 pre-built VPP packages built by Jenkins for the patch under review are then\r
39 installed on the two SUTs, along with their /etc/vpp/startup.conf file, in all\r
40 VIRL simulations.\r
41 \r
42 SUT Configuration - VIRL Guest VM\r
43 ---------------------------------\r
44 \r
45 Configuration of the SUT VMs is defined in file\r
46 \r
47    /csit/resources/tools/virl/topologies/double-ring-nested.xenial.virl\r
48 \r
49 - List of SUT VM interfaces:::\r
50 \r
51     <interface id="0" name="GigabitEthernet0/4/0"/>\r
52     <interface id="1" name="GigabitEthernet0/5/0"/>\r
53     <interface id="2" name="GigabitEthernet0/6/0"/>\r
54     <interface id="3" name="GigabitEthernet0/7/0"/>\r
55 \r
56 - Number of 2MB hugepages: 1024\r
57 \r
58 - Maximum number of memory map areas: 20000\r
59 \r
60 - Kernel Shared Memory Max: 2147483648 (vm.nr_hugepages * 2 * 1024 * 1024)\r
61 \r
62 SUT Configuration - VIRL Guest OS Linux\r
63 ---------------------------------------\r
64 \r
65 In CSIT terminology, the VM operating system for both SUTs that |vpp-release| has\r
66 been tested with, is the following:\r
67 \r
68 **#. Ubuntu VIRL image**\r
69 \r
70 This image implies Ubuntu 16.04.1 LTS, current as of yyyy-mm-dd (that is,\r
71 package versions are those that would have been installed by a "apt-get update",\r
72 "apt-get upgrade" on that day), produced by CSIT disk image build scripts.\r
73 \r
74 The exact list of installed packages and their versions (including the Linux\r
75 kernel package version) are included in CSIT source repository:\r
76 \r
77   resources/tools/disk-image-builder/ubuntu/lists/|virl-image-ubuntu|\r
78 \r
79 A replica of this VM image can be built by running the "build.sh" script in CSIT\r
80 repository resources/tools/disk-image-builder/ubuntu.\r
81 \r
82 **#. CentOS VIRL image**\r
83 \r
84 The Centos7.3 image is ready to be used but no tests running on it now.\r
85 Corresponding Jenkins jobs are under preparation.\r
86 \r
87 The exact list of installed packages and their versions (including the Linux\r
88 kernel package version) are included in CSIT source repository:\r
89 \r
90   resources/tools/disk-image-builder/ubuntu/lists/|virl-image-centos|\r
91 \r
92 A replica of this VM image can be built by running the "build.sh" script in CSIT\r
93 repository resources/tools/disk-image-builder/centos.\r
94 \r
95 **#. Nested VM image**\r
96 \r
97 In addition to the "main" VM image, tests which require VPP to communicate to a\r
98 VM over a vhost-user interface, utilize a "nested" VM image.\r
99 \r
100 This "nested" VM is dynamically created and destroyed as part of a test case,\r
101 and therefore the "nested" VM image is optimized to be small, lightweight and\r
102 have a short boot time. The "nested" VM image is not built around any\r
103 established Linux distribution, but is based on `BuildRoot\r
104 <https://buildroot.org/>`_, a tool for building embedded Linux systems. Just as\r
105 for the "main" image, scripts to produce an identical replica of the "nested"\r
106 image are included in CSIT GIT repository, and the image can be rebuilt using\r
107 the "build.sh" script at:\r
108 \r
109    resources/tools/disk-image-builder/ubuntu/lists/nested\r
110 \r
111 DUT Configuration - VPP\r
112 -----------------------\r
113 \r
114 Every System Under Test runs VPP SW application in Linux user-mode as a Device\r
115 Under Test (DUT) node.\r
116 \r
117 **DUT port configuration**\r
118 \r
119 Port configuration of DUTs is defined in topology file that is generated per\r
120 VIRL simulation based on the definition stored in file\r
121 \r
122    /csit/resources/tools/virl/topologies/double-ring-nested.xenial.yaml\r
