[Engine-devel] Source code unerstanding
by aditya mamidwar 16 Mar '14

Hey, is there a simpler way to know which code is responsible for which module of the engine. is there a documentation maintained. or how can identify the files which are important for me. -- -Aditya Mamidwar

I want to commit changes to the engine by adding some bash scripts. the scripts should be invoked once a button or tab is selected in the webadmin portal by the user. can someone guide on achieving this. -- -Aditya Mamidwar

[Engine-devel] attn ui devs: why do we use inputs for labels?
by Greg Sheremeta 14 Mar '14

14 Mar '14

Hi fellow UI developers, Can someone explain why we are using "input type=text" fields to render labels? (see screenshot[1]) This seems like bad practice for a few reasons: * it's not semantic HTML * inputs do not have variable sizing like text. They cannot shrink down to the size of the text, which makes positioning difficult. * common browser extensions such as LastPass can be confused (see screenshot[1] -- lastpass sees these labels for the text fields they are, and attempts to help the user fill them in -- that's what those gray asterisks are. Very confusing.) I'd like to pursue correcting this, if possible. Thanks, Greg [1] http://i.imgur.com/AweOhJe.png Greg Sheremeta Red Hat, Inc.

[Engine-devel] oVirt Engine 3.2 ReST API
by Vikas Kokare 11 Mar '14

11 Mar '14

As per the API documentation, the host cluster element "data_center id=" is both required at creation(exclamation in a triangle) as well as non-updatable(lock sign). Is it right to consider that, not only is this a required element, but it can't be changed and deleting(disassociation) is out of question? We have a RHEVM environment, where one such host cluster was created initially being associated to a data center. Later someone changed something, that resulted in the specific host cluster having no "data_center" element on it. Could it be that the association was deleted, or that the data_center itself was deleted, but the system didn't honor referential integrity, that it was being referred by other objects?

[Engine-devel] Fwd: [vdsm] ovirt-guest-agent on debian
by Sven Kieske 11 Mar '14

11 Mar '14

Forwarding to engine devel, because it seems there is no interest in this feature on vdsm-devel. Could this get integrated somehow? I managed to reuse the ubuntu build of ovirt-guest-agent for debian. -------- Original-Nachricht -------- Betreff: [vdsm] ovirt-guest-agent on debian Datum: Mon, 10 Mar 2014 09:36:11 +0000 Von: Sven Kieske <S.Kieske(a)mittwald.de> An: VDSM Project Development <vdsm-devel(a)lists.fedorahosted.org> Hi, I just did some additional research, here are my results: on a clean debian 7 x64 VM inside oVirt: I did as root: apt-get install python-software-properties add-apt-repository -y ppa:zhshzhou/vdsm-ubuntu vim /etc/apt/sources.list.d/zhshzhou-vdsm-ubuntu-wheezy.list change the following lines from: deb http://ppa.launchpad.net/zhshzhou/vdsm-ubuntu/ubuntu wheezy main deb-src http://ppa.launchpad.net/zhshzhou/vdsm-ubuntu/ubuntu wheezy main to: deb http://ppa.launchpad.net/zhshzhou/vdsm-ubuntu/ubuntu precise main deb-src http://ppa.launchpad.net/zhshzhou/vdsm-ubuntu/ubuntu precise main then: apt-get update apt-get install ovirt-guest-agent You get an error: Setting up ovirt-guest-agent (1.0.8.201309301944.gitb7f8f2-1ppa1) ... chown: cannot access `/var/log/ovirt-guest-agent/ovirt-guest-agent.log': No such file or directory but it works: ls -lashi /var/log/ovirt-guest-agent/ovirt-guest-agent.log 533212 4.0K -rw-r--r-- 1 ovirtagent ovirtagent 208 Mar 10 10:20 /var/log/ovirt-guest-agent/ovirt-guest-agent.log service ovirt-guest-agent status [ ok ] ovirt-guest-agent is running. IP information shows up in ovirt. it would be cool if the folder "precise" on the ppa could be cloned to be a folder "wheezy". So you would not need to change the apt-sources entries. I don't know why this chown error occurs, but it seems to work! -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
