Error: Adding new Host to ovirt-engine

Hi,
Can't add new host to ovirt engine, because the following error:

Error Java SDK Issue??
by Geschwentner, Patrick
Dear Ladies and Gentlemen!
I am currently working with the java-sdk and I encountered a problem.
If I would like to retrieve the disk details, I get the following error:
Disk currDisk = ovirtConnection.followLink(diskAttachment.disk());
The Error is occurring in this line:
[cid:image001.png@01D44537.AF127FD0]
The getResponst looks quiet ok. (I inspected: [cid:image002.png@01D44537.AF127FD0] and it looks ok).
Error:
wrong number of arguments
The code is quiet similar to what you published on github (https://github.com/oVirt/ovirt-engine-sdk-java/blob/master/sdk/src/test/j... ).
Can you confirm the defect?
Best regards
Patrick

OST's basic suite UI sanity tests optimization
by Marcin Sobczyk
Hi,
_TL; DR_ Let's cut the running time of '008_basic_ui_sanity.py' by more
than 3 minutes by sacrificing Firefox and Chrome screenshots in favor of
Chromium.
During the OST hackathon in Brno this year, I saw an opportunity to
optimize basic UI sanity tests from basic suite.
The way we currently run them, is by setting up a Selenium grid using 3
docker containers, with a dedicated network... that's insanity! (pun
intended).
Let's a look at the running time of '008_basic_ui_sanity.py' scenario
(https://jenkins.ovirt.org/view/oVirt%20system%20tests/job/ovirt-system-te...):
01:31:50 @ Run test: 008_basic_ui_sanity.py:
01:31:50 nose.config: INFO: Ignoring files matching ['^\\.', '^_',
'^setup\\.py$']

01:35:36 # Results located at

01:35:36 @ Run test: 008_basic_ui_sanity.py: Success (in 0:03:45)
Starting the Selenium grid takes 2:15 out of 3:35 of total running time!
I've investigated a lot of approaches and came up with something like this:
* install 'chromium-headless' package on engine VM
* download 'chromedriver' and 'selenium hub' jar and deploy them in
'/var/opt/' on engine's VM
* run 'selenium.jar' on engine VM from '008_basic_ui_sanity.py' by
using Lago's ssh
* connect to the Selenium instance running on the engine in
'008_basic_ui_sanity.py'
* make screenshots
This series of patches represent the changes:
https://gerrit.ovirt.org/#/q/topic:selenium-on-engine+(status:open+OR+sta....
This is the new running time (https://jenkins.ovirt.org/view/oVirt
system tests/job/ovirt-system-tests_manual/4195/):
20:13:26 @ Run test: 008_basic_ui_sanity.py:
20:13:26 nose.config: INFO: Ignoring files matching ['^\\.', '^_',
'^setup\\.py$']
20:13:26 # init:
20:13:26 # init: Success (in 0:00:00)
20:13:26 # make_screenshots:
20:13:27 * Retrying (Retry(total=2, connect=None, read=None,
redirect=None, status=None)) after connection broken by
'NewConnectionError('<urllib3.connection.HTTPConnection object at
0x7fdb6004f8d0>: Failed to establish a new connection: [Errno 111]
Connection refused',)': /wd/hub
20:13:27 * Retrying (Retry(total=1, connect=None, read=None,
redirect=None, status=None)) after connection broken by
'NewConnectionError('<urllib3.connection.HTTPConnection object at
0x7fdb6004fa10>: Failed to establish a new connection: [Errno 111]
Connection refused',)': /wd/hub
20:13:27 * Retrying (Retry(total=0, connect=None, read=None,
redirect=None, status=None)) after connection broken by
'NewConnectionError('<urllib3.connection.HTTPConnection object at
0x7fdb6004fb50>: Failed to establish a new connection: [Errno 111]
Connection refused',)': /wd/hub
20:13:28 * Redirecting http://192.168.201.4:4444/wd/hub ->
http://192.168.201.4:4444/wd/hub/static/resource/hub.html
20:14:02 # make_screenshots: Success (in 0:00:35)
20:14:02 # Results located at
/dev/shm/ost/deployment-basic-suite-master/008_basic_ui_sanity.py.junit.xml
20:14:02 @ Run test: 008_basic_ui_sanity.py: Success (in 0:00:35)
(The 'NewConnectionErrors' is waiting for Selenium hub to be up and
running, I can silence these later).
And the screenshots are here:
https://jenkins.ovirt.org/view/oVirt%20system%20tests/job/ovirt-system-te...
_The pros:_
* we cut the running time by more than 3 minutes
_The cons:_
* we don't get Firefox or Chrome screenshots - we get Chromium
screenshots (although AFAIK, QE has much more Selenium tests which
cover both Firefox and Chrome)
* we polute the engine VM with 'chromium-headless' package and deps
(in total: 'chromium-headless', 'chromium-common', 'flac-libs' and
'minizip'), although we can remove these after the tests
_Some design choices explained:_
Q: Why engine VM?
A: Because the engine VM already has 'X11' libs. We could install
'chromium-headless' (and even other browsers) on our Jenkins executors,
but that would mess them up a lot.
Q: Why Chromium?
A: Because it has a separate 'headless' package.
Q: Why not use 'chromedriver' RPM in favor of
https://chromedriver.storage.googleapis.com Chromedriver builds?
A: Because the RPM version pulls a lot of extra dependencies even on the
engine VM ('gtk3', 'cairo' etc.). Builds from the URL are the offical
Google Chromedriver builds, they contain a single binary, and they work
for us.
_What still needs to be polished with the patches:_
* Currently 'setup_engine_selenium.sh' script downloads each time
'selenium.jar' and 'chromedriver.zip' (even with these downloads we
get much faster set-up times) - we should bake these into the engine
VM image template.
* 'selenium_hub_running' function in 'selenium_on_engine.py' is
hackish - an ability to run an ssh command with a context manager
(and auto-terminate on it exits) should be part of Lago. Can be
refactored.
Questions, comments, reviews are welcome.

Proposing Andrej Krejcir as a maintainer of engine core
by Arik Hadas
Dear engine-core maintainers,
I'd like to propose Andrej Krejcir as a maintainer of oVirt engine backend.
Since Jul 2015, Andrej has been contributing to ovirt-engine, mostly in SLA
areas (scheduling, quota, etc) and recently being more and more involved
also in the VIRT areas. This results in ~200 patches to engine master alone.
Personally, I reviewed some of Andrej's contributions and noticed reviews
made by Andrej to others. I sincerely believe Andrej would be a good
addition to the maintainers' group.
Thanks in advance for your response!

Getting "Could not fetch dashboard data. Please ensure that data warehouse is properly installed and configured" after upgrading RHV 4.2 to 4.3
by Lynn Dixon
I attempted to upgrade a hosted engine environment that was running RHV 4.2
to RHV 4.3 and everything appeared to have worked fine. Except when I
login to the webui, I get the error in the dashboard that "Could not fetch
dashboard data...."
I see the dwhd service is running, and I noticed that there was a
postgresql upgrade in the engine-setup, but I did not see any errors or
oddness during the upgrade process.
Is there something I am missing?

USB on host support?
by Hetz Ben Hamo
Hi,
I'm in communication with a company that thinks about RHV.
One of the requirements is USB host support (which will be on the nodes,
not on the desktops). I haven't found any way to connect USB to a VM other
then through SPICE, but this method won't help as these dongles won't be on
desktops.
Is this in the road map of oVirt?
Thanks
