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

Important! Zones must be placed to the /zones directory like dhcp zone.

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

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:

ztest@dilos:~# cat > sz.cfg <<EOT
create
set zonepath=/zones/sz
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 -f sz.cfg

and for the rz zone:

ztest@dilos:~# cat > rz.cfg <<EOT
create
set zonepath=/zones/rz
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 -f rz.cfg

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:

apt download socat

For the current version, the name of the downloaded file is socat_1.7.3.1-2+deb9u1+dilos2_solaris-i386.deb

Install it into the zones:

sudo apt -y -o Dir=/zones/cz-orig/root update
sudo apt -y -o Dir=/zones/cz-orig/root upgrade
sudo dpkg -i --root=/zones/cz-orig/root socat_1.7.3.1-2+deb9u1+dilos2_solaris-i386.deb

sudo apt -y -o Dir=/zones/sz-orig/root update
sudo apt -y -o Dir=/zones/sz-orig/root upgrade
sudo dpkg -i --root=/zones/sz-orig/root socat_1.7.3.1-2+deb9u1+dilos2_solaris-i386.deb

sudo apt -y -o Dir=/zones/rz-orig/root update
sudo apt -y -o Dir=/zones/rz-orig/root upgrade
sudo dpkg -i --root=/zones/rz-orig/root socat_1.7.3.1-2+deb9u1+dilos2_solaris-i386.deb

sudo reboot

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. To do this you should put the number of cycles in parameters of the test script:

./stability-test.sh <N>

where <N> is the number of passes. For example, to run 1000 passes enter ./stability-test.sh 1000. 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.
