[Engine-devel] The correct way to create test dependencies between
by Allon Mureinik 14 May '12

14 May '12

Hi guys, I've recently come up with (what I believe is) an elegant way to mock the Config object using JUnit @Rules and Mockito (The gritty details can be found at http://gerrit.ovirt.org/4155) This presented me with another issue: On the one hand, the code depends on junit and mockito jars, which are not available in the main scope, only in the test scope. On the other hand, in vanilla Maven there is no dependency between tests of different projects, so placing this class in util's test would make it inaccessible to bll tests. The solution Maven suggests for these kind of issues is creating a test jar (http://maven.apache.org/guides/mini/guide-attached-tests.html) In addition to the regular jar the module produces, you'll get another -test jar, which other modules can depend on using the <type>test-jar</type>, which could of course be put in <scope>test</scope>. Before pushing forward with this approach, I'd like to know if anyone has a principle objection to it. Thanks, Allon

[Engine-devel] value too long for type character varying(20) in function "insertvds_interface"

[Engine-devel] Questions on NIC hotplug (http://www.ovirt.org/wiki/Features/Design/DetailedHotlugNic)
by Yaniv Kaul 13 May '12

13 May '12

1. I wasn't sure from the description, but can one change the Network to which a NIC is connected to when it's up? (looks like a much lighter and reasonable action than unplugging-changing-plugging. Also very easy to do in the physical world). I'm quite sure there's a request for such a feature. 2. The REST API usage of 'activate' and 'deactivate' is certainly not inline with the UI's terminology, which is not only a shame, but is also (to me) confusing with setting the NIC's link up/down (which is possible in QEMU, not sure if we do it in oVirt). the UI concept of arrows also seem to support 'up'/'down' ... 3. Donno if it's just the mock ups, but lets try to use 'Network Card' over 'NIC' where possible. 4. I'm not sure why do we need the 'plug' and 'unplug' buttons, and can't do it in the 'Edit' dialog box. I think it's confusing. 5. How do I create a non-plugged NIC via the API? How do I see if a VM's NIC is plugged or not via the API? 6. SDK example would be great too.

[Engine-devel] oVirt UserPortal changes
by Vojtech Szocs 10 May '12

10 May '12

Hi everyone, there were some important changes regarding UserPortal introduced recently, so I'll try to summarize the main points here. Please refer to [http://gerrit.ovirt.org/4273] for more details. - legacy (SmartGWT-based) UserPortal is no longer built/compiled during standard oVirt Maven build In case you still want to build/deploy original UserPortal: 1. uncomment "userportal-legacy" sections in ear/pom.xml 2. in frontend/webadmin/modules/pom.xml, include <module>userportal</module> within the <modules> section 3. use "gwt-user-legacy" profile when building oVirt - profile "gwt-user-gwtp" is replaced with "gwt-user", this triggers compilation of new (GWTP-based) UserPortal For example, to build oVirt with WebAdmin and new UserPortal: mvn clean install -Psetup,dep,gwt-admin,gwt-user - UserPortal host page URL has changed to: http(s)://<server-address>[:<port>]/UserPortal/org.ovirt.engine.ui.userportal.UserPortal/UserPortal.html This reflects the URL of original UserPortal. Feel free to contact me if you have any questions. Thanks, Vojtech

[Engine-devel] Stuck at the firewall.conf in vds_bootstrap
by Shu Ming 09 May '12

09 May '12

Hi, My vds_installer was stuck at running vds_bootstrap when I tried to add one host node in my ovirt-engine. For some reasons, the /tmp/firewall.conf.* file was not downloaded and that caused vds_bootstrap's failure. Is there any quick way to disable the "-f" option for vds_bootstrap in engine server or in host node? That will not allow vdsm to overwrite the firewall configurations in host. --- From the vds_install.xxxxxx.log in my host, here is the command where the vds_installer was stuck. /tmp/vds_bootstrap_1a9728df-e3b4-4d7b-8258-835038587bad.py -v -O cstl -t 2012-05-09T16:00:04 -f /tmp/firewall.conf.1a9728df-e3b4-4d7b-8258-835038587bad http://ovirt-engine-112:80/Components/vds/ 9.181.129.110 1a9728df-e3b4-4d7b-8258-835038587bad -- Shu Ming<shuming(a)linux.vnet.ibm.com> IBM China Systems and Technology Laboratory
