[Engine-devel] REST for non-admin account
by Marc-André Lureau 23 Nov '11

23 Nov '11

Hi Is there any plan making part of the REST api accessible for non-admin accounts? How can I request and track such a feature? Is ovirt still using bugzilla.redhat.com for bugs? thanks -- Marc-André Lureau

[Engine-devel] First Nightly build of ovirt-engine & VDSM + Installation Guides
by Ronen Angluster 23 Nov '11

23 Nov '11

Hello, We've published 2 guides that describe how to install & configure ovirt-engine & VDSM from a nightly build placed on ovirt.org's repository. http://www.ovirt.org/wiki/Installing_ovirt_from_rpm http://www.ovirt.org/wiki/Installing_VDSM_from_rpm Please note the following: 1. At the time, nightly builds are not going to be carried out "nightly", we will publish new versions from time to time until we'll establish a mature and working release process 2. The installation process contains interim steps and will change as we mature the ovirt-engine product's deployment and may change significantly between revisions. Regards, Ronen Angluster

[Engine-devel] Pain Points: Adding NFS Storage
by Steve Gordon 22 Nov '11

22 Nov '11

Hi guys, By far the most common query that I have seen posed in the IRC channel since the workshop has been around how to successfully add an NFS storage domain. I know there are a host of reasons that this can fail (NFSv4 instead of NFSv3, path is not chown'd 36:36, firewall/server not reachable, bad export configuration) but it's still a pretty obvious pain point and it can be difficult to walk people through troubleshooting all of these possibilities on IRC. I haven't filed a bug around this (yet) but I thought it might be worth trying to come with some ideas for what, if anything, we can change code wise to make this easier for people (and more obvious exactly what is actually wrong when it doesn't work) and then maybe some bugs can be raised from that? I have also created the following page to attempt to collate the requirements for an NFS share to be used by oVirt and how to troubleshoot this issue, please feel free to contribute: http://www.ovirt.org/wiki/Troubleshooting_NFS_Storage_Issues Thanks, Steve

[Engine-devel] Classifying engine errors
by Michael Pasternak 21 Nov '11

21 Nov '11

Hi, i would like to suggest classifying engine errors (VdcBllMessages) using these categories: 100-199. entity not found 200-300. missing parameters 300-399. no resources available 400-499. can't perform - user error 500-599. can't perform - server error 600-699. Unauthorized 700-x. Forbidden this way rest api will be able mapping them to HTTP errors e.g any error returned by engine CAN_DO_ACTION 100 < x < 200 will be converted to HTTP 404 with CAN_DO_ACTION message detail - this can be easily done by assigning id to each VdcBllMessages enum member in range of one of mentioned categories. -- Michael Pasternak RedHat, ENG-Virtualization R&D -- Michael Pasternak RedHat, ENG-Virtualization R&D

[Engine-devel] logging in engine
by Laszlo Hornyak 21 Nov '11

21 Nov '11

Hi, In oVirt's logging configuration we direct org.ovirt.* loggers to the engine log appender, org.ovirt.engine.ui to the ui's log and then the rest to the server log. The difficulties come when you start to do cross-component debugging. E.g. you see the logs of the engine in the engine log, but you would also like to see the logs of the components the engine is building upon: persistence API's (jdbc, hibernate) network communication components (e.g. httpclient, vdsm, ssh client), data processing API's (xml or json-parsers, apache commons apis) and all these logs go to the generic engine log. So when debugging you would have to merge these logs, otherwise you may miss some important details. I believe Moti's patch (http://gerrit.ovirt.org/#patch,sidebyside,257,3,backend/manager/conf/jboss-…) is one step in the another (I believe more useful) direction. But rather than specifying all the components that the engine uses, wouldn't it make sense to take just let all the logs flow into a single appender? What is your opinion? Thank you, Laszlo
