Hi,

I am trying the "board-at-desk-single-dev" project (sorry to do it so late).
I managed to build the CIP kernel and see the job results using KernelCI.
However, I am having problems with LAVA health checks (see at the end).

First, I would like to report on a few problems I had to solve to get the kernel built:

*************************************************
1) Although now I know that the current development occurs at
https://gitlab.com/cip-project/board-at-desk-single-dev.git
googling "CIP kernelci" gives also the following outdated (?) sites which can
be confusing:
https://github.com/cip-project/cip-kernelci.git

the github ressource is here for historic reasons. Unless anyone
disagrees, I'm going to remove it.

Thanks, Wolfgang

https://gitlab.com/cip-project/kernelci-debian.git

Q: are they necessary? or is it some misunderstanding from my side?

2) Problems behind a proxy

a) I did the following to setup proxy settings for vagrant on Ubuntu 16.04 Xenial:

$ sudo apt-get remove vagrant <-- gives errors when installing vagrant-proxyconf
$ dpkg -i vagrant_1.9.4_x86_64.deb
$ vagrant plugin install vagrant-proxyconf
$ vi Vagrantfile
+ if Vagrant.has_plugin?("vagrant-proxyconf")
+ config.proxy.http = "http://xxx:yyyy/"
+ config.proxy.https = "https://xxx:yyy/"
+ config.proxy.no_proxy = "127.0.0.1,localhost,xxxx."
+ end

Q: maybe it would be good to add this to the tutorial

b) I got an error during vagrant up

==> default: fatal: [kernel-ci-backend]: FAILED! => {"changed": false, "cmd": "/usr/bin/apt-key adv --keyserver hkp://keyserver.ubuntu.com --recv EA312927", "failed": true,
- Solved it by adding port 80 for apt-key
$ vagrant ssh
guest$ vi kernelci-backend/roles/install-deps/tasks/install-mongodb.yml
- hkp://keyserver.ubuntu.com
+hkp://keyserver.ubuntu.com:80
[Alt] sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927

Q: if that works without proxies, maybe it should be set to 80 by default?

c) I got a lot of warnings like these ones

- Warning 1 (ignore)
GetPassWarning: Can not control echo on the terminal.” or “Warning: Password input may be echoed.” - These do not affect the operation of the KernelCI VM.
- Warning 2 (ignore)
==> default: lava_scheduler_app.Notification.job_status_trigger: (fields.W901) CommaSeparatedIntegerField has been deprecated. Support for it (except in historical migrations) will be removed in Django 2.0.
==> default: HINT: Use CharField(validators=[validate_comma_separated_integer_list]) instead.

Q: The tutorial mentions Warning 1, but not Warning 2. Maybe adding that would be a good idea.

3) Modifying the 8080 port (very commonly used port, e.g. Fuego ;_+)

I solved this by
$ vi Vagrantfile
+ config.vm.network :forwarded_port, guest: 8081, host: 8081
$ sudo vi /etc/apache2/ports.conf
-> change to 8081
$ sudo vi /etc/apache2/sites-enabled/lava-server.conf
-> change to 8081
$ sudo service apache2 restart
$ sudo /etc/init.d/lava-server restart

Q: maybe this could be automated (?)
*************************************************

Second, regarding to LAVA health checks I think this is again a problem with being behind a
proxy but I'm not sure how to debug it. These are the error messages that I get
with QEMU's health check (/vagrant/tests/qemu-health-check.yaml)

- log:

If someone has a clue about this please let me know.
# http_proxy-like variables are all defined in the VM (/etc/environment), and I can use wget and download
stretch-2.img.gz without problems.

Best regards,
Daniel
