Setup VM with:

Create user:

sudo useradd -m -d /var/ztest -g staff -s /bin/bash ztest
# add password for remote ssh
sudo passwd ztest

Add user to sudo:

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

Install packages for net tests:

sudo apt update
sudo apt install system-test-nettest testrunner python

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 in the / zones directory

Create dataset:

sudo zfs create -o mountpoint=/zones rpool/zones

Set network interfaces for dhcp

sudo dladm create-etherstub vsw0

sudo dladm create-vnic -l vsw0 int0

set config file interface /etc/hostname.int0

192.168.0.254 netmask 255.255.255.0 broadcast + up

reboot system

Set dhcp for zones

use this guide How to configure ISC DHCP server

Configure zones

The zone configuration should be considered for the cz zone, for other zones, the setting is the same:

cat>cz.cfg <<EOT
create
set zonepath=/zones/cz
set autoboot=true
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
sudo zonecfg -z cz -f cz.cfg

The zone configuration should be considered for the sz zone, for other zones, the setting is the same:

cat>sz.cfg <<EOT
create
set zonepath=/zones/sz
set autoboot=true
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
sudo zonecfg -z sz -f sz.cfg

The zone configuration should be considered for the rz zone, for other zones, the setting is the same:

cat>rz.cfg <<EOT
create
set zonepath=/zones/rz
set autoboot=true
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
sudo zonecfg -z rz -f rz.cfg

Install and run zones (example for zone cz):

sudo zoneadm -z cz install
sudo zoneadm -z cz boot

Install the socat package for every zone:

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

Download it in the global zone:

apt download socat

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

Install into the zones (example for zone cz):

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

Launch tests:

sudo /opt/net-tests/bin/nettest

Wait for several minutes and have found full logs at:
