QA (public) » openQA Project (public)

I tried setting it up with Wicked and network with both, Wicked and Network manager.

Currently the machine has wicked configured but can be reinstalled if needed

On a fresh leap 15.6 install I am trying to setup a multi-machine cluster using this script as mentioned in the documentation: (machine setup is simple https://en.opensuse.org/openSUSE:OpenQA:Setup)

instances=2 ethernet=eth1 bash -x $(which os-autoinst-setup-multi-machine) (machine has two network interfaces)

unfortunately after this the tests fail with

 qemu-system-x86_64: -netdev tap,id=qanet0,ifname=tap21,script=no,downscript=no: could not configure /dev/net/tun (tap21): Operation not permitted

I found this exact error easily reproducible in case of NetworkManager.
I didn't get the firewall error though. Also, to me it seems like openQA-worker along with multi-machine installation and setup was done via official repositories

Trying to reproduce the issue, performing a fresh openSUSE Leap 15.6 installation

@gpathak Could you try to reproduce it on one of the quake machines I assume that there are some differences in setup

Sure, I will try to reproduce it on one of the quake machines.

I tried this on quake2.qe.nue2.suse.org, and the execution was successful: http://10.168.195.106/tests/13#dependencies

I didn't perform a fresh Leap 15.6 installation on quake2, instead I removed the packages and re-installed the PACKAGES, I have listed the commands that I executed (after some trial and error) for removing, re-installing and configuring openQA and multimachine setup

zypper rm openQA* os-autoinst* firewalld* openvswitch* apache2*
rm -rvf /etc/openqa/
rm -rvf /var/lib/openqa/
rm -rf /etc/firewalld
rm -rf /etc/openvswitch/
find / -name "*openqa*" | xargs rm -rvf
find / -name "*apache2*" | xargs rm -rvf
find / -name "*openqa*" | xargs rm -rvf
reboot

After the machine booted, logged in via ssh and followed https://en.opensuse.org/openSUSE:OpenQA:Setup

zypper ref
zypper in openQA-bootstrap firewalld firewalld-bash-completion firewalld-lang firewalld-test
systemctl enable --now firewalld.service
skip_suse_specifics=1 skip_suse_tests=1 /usr/share/openqa/script/openqa-bootstrap
firewall-cmd --zone=public --add-service=http --permanent
firewall-cmd --add-port=5991/tcp --permanent
firewall-cmd --add-port=5992/tcp --permanent

I don't know why the above command firewall-cmd --zone=public --add-service=http --permanent didn't work, I had to explicitly run:

firewall-cmd --permanent --add-port=80/tcp --zone=public
firewall-cmd --permanent --add-port=80/udp --zone=public
firewall-cmd --reload

Then added tap worker class in workers.ini after that:

systemctl enable --now openqa-worker-plain@{1..2}.service
systemctl restart openqa-worker-plain@{1..2}.service
instances=2 ethernet=eth0 bash -x $(which os-autoinst-setup-multi-machine)
systemctl restart os-autoinst-openvswitch.service
wicked ifup all
openqa-clone-job --skip-chained-deps --show-progress https://openqa.opensuse.org/tests/4942922

The multimachine test didn't pass in first attempt.

I have to run systemctl restart os-autoinst-openvswitch.service openvswitch.service and then wicked ifup all to get rid of this error Open vSwitch command 'set_vlan' with arguments 'tap1 1' failed: org.freedesktop.DBus.Error.ServiceUnknown: The name org.opensuse.os_autoinst.switch was not provided by any .service files: http://10.168.195.106/tests/10#line-68
then I have to install ffmpeg-4 to make it work http://10.168.195.106/tests/9#line-46 and fix this error Can't exec "ffmpeg": No such file or directory at /usr/lib/os-autoinst/backend/baseclass.pm line 348, <$fh> line 16.

But I didn't get any of the error:

qemu-system-x86_64: -netdev tap,id=qanet0,ifname=tap21,script=no,downscript=no: could not configure /dev/net/tun (tap21): Operation not permitted

Error: RUNNING_BUT_FAILED: Changing permanent configuration is not allowed while firewalld is in FAILED state. The permanent configuration must be fixed and then firewalld restarted. Try firewall-offline-cmd --check-config.

Configuration error: INVALID_INTERFACE: Zone 'public': interface 'eth1' already bound to zone 'trusted'

PLease let me know how can I perform a fresh Leap 15.6 installation on quake2 and then I can perform these steps mentioned in the wiki on quake2 from scratch

Did a fresh Leap 15.6 installation on quake2 (with wicked), will be performing these setup steps: https://en.opensuse.org/openSUSE:OpenQA:Setup

Indeed, I got this error:

Error: RUNNING_BUT_FAILED: Changing permanent configuration is not allowed while firewalld is in FAILED state. The permanent configuration must be fixed and then firewalld restarted. Try `firewall-offline-cmd --check-config`.

Created a MR: https://github.com/os-autoinst/os-autoinst/pull/2685

Tests passed: http://quake2.qe.nue2.suse.org/tests/5#dependencies

Verified with the changes made recently in the MR for review comments.
MM tests doesn't complain could not configure /dev/net/tun (tap21): Operation not permitted, os-autoinst-setup-multi-machine also takes care of setting interface in correct firewalld zone

Test execution result: http://quake2.qe.nue2.suse.org/tests/2

Thanks for looking into this, I will reinstall quake2 and report back whether there are more issues or if everything was running fine

You can re-install OS on quake2, but the MR is not yet approved and merged, I tested these changes locally.

just had a chance to verify this, thanks @gpathak
