[Engine-devel] Jenkins Continuous Integration Server for oVirt is up and running!
by Eyal Edri 19 Jan '12

19 Jan '12

fyi, oVirt project now has a Jenkins CI server[1] on http://jenkins.ovirt.org. The CI server runs various jobs on oVirt components *[2] such as ovirt-engine,ovirt-node,etc.. Every commit to gerrit.ovirt.org will trigger the job 'ovirt_engine' which will run 'maven' build and verify that the commit didn't break the code. If the commit did break the code, it will send an alert email to "engine-patches.ovirt.org" and to the commiter with a link to a log console containing the error. On success, the job will trigger other jobs such as "find_bugs", "gwt profiles", "create db", "unit-tests", each testing a different part of the code. In time, more and more jobs will be added to jenkins, which will allow us to catch bugs much faster than before, and to improve code quality even more. If you have questions, don't hesitate to ask me or infra(a)ovirt.org. [1] http://jenkins-ci.org/ [2] currently only ovirt-engine is configured and working. Eyal Edri oVirt infrastructure team

Hello, Is there any way to get more than 100 VMs (or whatever the value of the option "SearchResultsLimit" is) using the REST API?

[Engine-devel] the future of template cloning
by Jon Choate 18 Jan '12

18 Jan '12

We are going to be able to store the disks for a template on different storage domains due to the multiple storage domain feature. Cloning a template will still be possible, but will it provide any value? Thoughts?

[Engine-devel] a different approach to the command classes
by Jon Choate 18 Jan '12

18 Jan '12

The way the command classes are written has bothered me for a while. While implementing the multiple storage domain features I am presented with the opportunity to create a new command from scratch. I gave some thought to what I would like the command classes to look like while balancing that the class must still fit in with the existing structure. So here is what I came up with. I'd appreciate any feedback. The Command class encompasses only the rules of what needs to be done. It relies upon Validator classes to determine if the canDoAction conditions have been met. @Override public boolean canDoAction() { ... checkTargetDomainHasSpace(); checkTargetDomainIsValidTarget(); checkSourceDomainIsValidSource(); checkSourceAndTargetAreDifferent(); ... } ... private void checkTargetDomainHasSpace() { if(!actionAllowed) return; if(!targetDomainValidator.hasSpace(getParameters().getDiskImageId())) { addCanDoActionMessage(VdcBllMessages.ACTION_TYPE_FAILED_DISK_SPACE_LOW); actionAllowed = false; } } Each of the checks follows a similar pattern of - guard clause to see of we already failed and bail if we did - test for failure of the condition - add failure message if needed - set variable to failed if needed Storing the success flag in a variable allows us to keep the canDoAction method readable as a series of commands and to allow it to be accessed by all the private methods without them having to pass it around. The execution of the command will follow a similar pattern where the command class will only know how to describe what needs to be done and to rely on supporting objects to handle the implementation of these steps. Getting the implementation out of the command classes will allow the commands to share validation and implementation details and remove a lot of the duplication that currently exists within the commands. How do people feel about this approach?

[Engine-devel] move disk command
by Jon Choate 18 Jan '12

18 Jan '12

As part of the multiple storage domains feature there will be new functionality added to allow users to move individual disks. What are the prerequisites for moving a disk? 1) the disk must exist 2) the associated VM must be down 3) the associated VM must not be locked 4) the source storage domain must exist 5) the source storage domain must be available 6) the target domain must exist 7) the target domain must be available 8) the target domain must have adequate disk space 9) the target domain cannot be an ISO or export domain 10) the source domain cannot be an ISO or export domain What am I missing? Also, should we allow the moving of a template disk that has VM disks based on it? Unless I'm wrong this would require all of the disks based on the template to be moved as well. thoughts?

[Engine-devel] New oVirt-engine RPMs available
by Ofer Schreiber 17 Jan '12

17 Jan '12

Hi all, We've just finished uploading a new set of oVirt-engine rpms into ovirt.org. In this version, we're very excited to introduce the support for JBoss AS7, the latest release of the JBoss community. These rpms are considered as candidates for our first release, aimed for January 31st, and will be tested during our official test day [1] tomorrow. Please note that due to the nature of nightly builds, and due to the massive changes required in order to support JBoss AS7, we recommend a clean environment to be used with the new set of rpms. In order to install the RPMs, please follow the instructions described in http://www.ovirt.org/wiki/Installing_ovirt_from_rpm Feedback, comments and bug reports are always welcome. The oVirt-Engine team [1] http://www.ovirt.org/wiki/Testing/OvirtTestDay
