How to run STABILITY tests on VM environment

1. Setup VM with:

CPU - 4
Memory - 8GB
Hard disk - 100GB
Have to use DEBUG build, where we have debug macro

Setup process is described in this instruction.

Note : If you already created dilos_BASE BE according the instruction, and there is no any new tested stable version, just execute the following command:

beadm activate dilos_BASE

In other case if you have already the dilos_ISO_orig BE - make the command:

beadm activate dilos_ISO_orig

Then reboot and start the instruction from the section Step 6. Prepare VM for Tests Running:

reboot

If you have no one of these 2 BEs then start the instruction from the beginning.

Note : Create ztest user if you forgot to do it according the instruction:

sudo useradd -m -d /var/ztest -g staff -s /bin/bash ztest

sudo passwd ztest

echo "ztest ALL=(ALL:ALL) NOPASSWD: ALL" >> /etc/sudoers.d/ztest

2. Install packages for net tests:

Note : If you already did it on the previous step when preparing VM to run, then you can skip this step and go to the next one.

sudo apt update
apt install testrunner python3 build-essential screen
apt install system-test-utiltest libjedec1 libdemangle-sys1 diagnostic-pci
apt install system-test-libctest system-test-elftest system-test-ostest system-test-nettest

3. Login by user ztest and create zones:

Zones must be created according to the file:
/opt/net-tests/config/ip_forwarding.config
Currently accepted names: cz, sz, rz

You can use the installation script or do the following steps.

First configure and install template zones cz-orig, sz-orig and rz-orig, from which test zones will be created later:

ztest@dilos:~# cat > cz-orig.cfg <<EOT
create
set zonepath=/zones/cz-orig
set autoboot=false
set ip-type=exclusive
add net
set physical=int1
set global-nic="vsw0"
add property (name="ip",value="dhcp")
add property (name="primary",value="true")
end
commit
exit
EOT
ztest@dilos:~# sudo zonecfg -z cz-orig -f cz-orig.cfg && sudo zoneadm -z cz-orig install

ztest@dilos:~# cat > sz-orig.cfg <<EOT
create
set zonepath=/zones/sz-orig
set autoboot=false
set ip-type=exclusive
add net
set physical=int2
set global-nic="vsw0"
add property (name="ip",value="dhcp")
add property (name="primary",value="true")
end
commit
exit
EOT
ztest@dilos:~# sudo zonecfg -z sz-orig -f sz-orig.cfg && sudo zoneadm -z sz-orig install

ztest@dilos:~# cat > rz-orig.cfg <<EOT
create
set zonepath=/zones/rz-orig
set autoboot=false
set ip-type=exclusive
add net
set physical=int3
set global-nic="vsw0"
add property (name="ip",value="dhcp")
add property (name="primary",value="true")
end
commit
exit
EOT
ztest@dilos:~# sudo zonecfg -z rz-orig -f rz-orig.cfg && sudo zoneadm -z rz-orig install

Now configure test zones. The following is the configuration for the cz zone:

ztest@dilos:~# cat > cz.cfg <<EOT
create
set zonepath=/zones/cz
set autoboot=false
set ip-type=exclusive
add net
set physical=int1
set global-nic="vsw0"
add property (name="ip",value="dhcp")
add property (name="primary",value="true")
end
commit
exit
EOT
ztest@dilos:~# sudo zonecfg -z cz -f cz.cfg

For other zones settings will be the same. For the sz zone:

and for the rz zone:

Install the socat package for every template zone

The zones have not configured net, need to install it from the global zone. Download the package inside the global zone:

(for the current version, the name of the downloaded file is socat_1.7.3.1-2+deb9u1+dilos2_solaris-i386.deb) and install it into the zones:

4. Login by user ztest and run tests

Copy the attached stability-test.sh to your test VM. Then check that dhcp zone and server are running after reboot and run tests.

The test script could be run in 3 modes:

for a specific number of iterations

In this case you have to put the -i option and enter the number of iterations, for example, to set 10 iterations:

to work for the specific period of time

In this case you have to put the -d option and enter the time duration in the HH:MM[:SS] format, for example, to work for 10 hours and 15 minutes:

or, for example to work for 20 seconds:

and finally to stop at the specified date and time

In this case you have to put the -t and enter the date and time of stop in the HH:MM[:SS] [DAY-MONTH_YEAR] format, for example, to work from the start to 17:00 of 8th of August 2023 year you will enter:

If date is omitted, and only time is entered, it’s supposed that date is the current one. I.e. to stop today at 19:00 you will enter:

You can run tests not only sequentially but randomly as well. To do this you have put the -s option at he end of command line, for example:

And finally you can run one specific test instead of the whole set. To do this you have to put its name at the end of the command line. The name can be one of libc, elf, os, util or net, for example:

And now after script is finished the common logs will be placed to /var/tmp/elf-stability.<ISO TIME>.txt, /var/tmp/libc-stability.<ISO TIME>.txt, /var/tmp/os-stability.<ISO TIME>.txt, /var/tmp/util-stability.<ISO TIME>.txt and /var/tmp/net-stability.<ISO TIME>.txt files. And you will find logs about separate cycles in elf.<N>.txt, libc-test.<N>.txt, ostest-test.<N>.txt, util-test.<N>.txt and net-test.<N>.txt form in the /var/tmp folder, where <N> - is a cycle number. The common information will be written in file /var/tmp/stability.<ISO TIME>.txt - start time, stop time, number of iterations, total execution time and failed test name in the case of fail.
