[Users] crafting a POST request to the oVirt API manually
by i iordanov 04 Dec '13

04 Dec '13

Hello, Can somebody give me some pointers on how to craft POST requests to the API "by hand" with (for example) a Firefox plugin like Poster: https://addons.mozilla.org/en-US/firefox/addon/poster/ It would be very helpful for libgovirt development. Thanks! iordan -- The conscious mind has only one thread of execution.

[Users] Fwd: [Engine-devel] Adding users and assigning roles in Ovirt
by Einav Cohen 04 Dec '13

04 Dec '13

[moving discussion to the users mailing list] while it seems that we all agree that adding some sort of a wizard that will allow easy permission assignment to newly-added users, it doesn't seem like something that can be accomplished soon (e.g. for ovirt 3.4). maybe we can utilize Ramesh's initial suggestion [1] for the short term - allow assignment of *System* permissions in the context of the 'Add User(s)' dialog [with an explicit clarification within the dialog that we are talking about *System* permissions, so that the admin will be aware that the privileges that he can assign in this context would be very permissive] any thoughts? how extensively are system permissions used in oVirt in general? [if adding a system permission is not a common/popular action, there is no reason to expose it in the 'Add User(s)' dialog, since it will probably be hardly used anyway] maybe different ideas for short-term solutions? ---- Thanks, Einav [1] http://lists.ovirt.org/pipermail/engine-devel/2013-December/006059.html ----- Forwarded Message ----- From: "Yair Zaslavsky" <yzaslavs(a)redhat.com> To: "Einav Cohen" <ecohen(a)redhat.com> Cc: "Oved Ourfalli" <ovedo(a)redhat.com>, engine-devel(a)ovirt.org Sent: Monday, December 2, 2013 4:09:10 PM Subject: Re: [Engine-devel] Adding users and assigning roles in Ovirt ----- Original Message ----- > From: "Einav Cohen" <ecohen(a)redhat.com> > To: "Malini Rao" <mrao(a)redhat.com> > Cc: "Oved Ourfalli" <ovedo(a)redhat.com>, engine-devel(a)ovirt.org > Sent: Monday, December 2, 2013 9:55:45 PM > Subject: Re: [Engine-devel] Adding users and assigning roles in Ovirt > > > ----- Original Message ----- > > From: "Malini Rao" <mrao(a)redhat.com> > > Sent: Monday, December 2, 2013 2:20:06 PM > > > > Joining in the thread a bit green but wouldn't it be ok to add the new user > > with the most basic permissions by default ( may be just read only > > permissions)until the admin goes and deliberately tweaks permissions or > > assigns a role? > > this is similar to what Oved has suggested, but I think that it won't really > make any difference, since there is very little chance, in my view, that > these > permissions would be sufficient for anything - the admin would need to assign > additional/different permissions at some point anyway, so not much point in > allowing that default minimal assignment in the first place - we might as > well > keep the 'Add User(s)' dialog as is. > > > > > Also, if we add that roles drop down as Einav mentioned, isn't there a way > > to > > only show that drop down if the logged in user is an admin role? > > the logged in user must be an admin, as the 'Add User(s)' dialog (which is > available from the Users main tab) exists only in the web-admin, which is > accessible only to admins by definition. > > > > > +1 on the user adding wizard.

[Users] How to backup thin provisioned qcow2 disks?

Live storage migration converted my disks from preallocated to thin provisioning. Preallocated disk backups are working from a simple dd from a snapshot, but the thin qcow2 disks are a problem. I seems it uses multiple logical volumes (3 in my case). Also they are combined MUCH bigger than the preallocated: 8GB raw vs thin: 31 GB - 1 snapshot. So I have two questions: - how would you backup these thin disks? - is it possible to convert thin to preallocated and discard the snapshots thanks -- Ernest Beinrohr, AXON PRO DevOps, Ing <http://www.beinrohr.sk/ing.php>, RHCE <http://www.beinrohr.sk/rhce.php>, RHCVA <http://www.beinrohr.sk/rhce.php>, LPIC <http://www.beinrohr.sk/lpic.php>, VCA <http://www.beinrohr.sk/vca.php>, +421-2--6241-0360 <callto://+421-2--6241-0360>, +421-903--482-603 <callto://+421-903--482-603> icq:28153343, skype:oernii-work <callto://oernii-work>, jabber:oernii@jabber.org ------------------------------------------------------------------------ For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.

[Users] CentOS upgrade from 3.2 to 3.3
by Karli Sjöberg 03 Dec '13

03 Dec '13

Hi all! Just wanted to express my deepest admiration for the progress of this project. You may or may not remember my quest for upgrading from 3.1 to 3.2 and just how difficult a seemingly trivial thing can turn out to be quite the ordeal... This time around, we followed this post by dreyou on how to go from his 3.2-repo to the ovirt.org stable repo 3.3: http://wiki.dreyou.org/dokuwiki/doku.php?id=ovirt_rpm_start33 And the whole process _just worked_! Something that actually made me even more nervous, left me feeling like "OK, so this is going just too well, I´ve got a bad feeling about this...":) But no, nothing ever blew us out the sky and the entire process of upgrading the engine and six hosts went through in just under the hour from start to finish! Best part is of course that our customers VM´s never even noticed; a completely live upgrade. Awesome! I mean, I worked my ass off trying to go from 3.1 to 3.2, I´ve actually put a mental block on the actual time it took, but probably six months of planning and trial and error, to have this done in under an hour... All I can say is THANK YOU! Both to you developers of oVirt and a special thank you to dreyou for posting such a well-written manual. Thank you. Thank you. Thank you:) -- Med Vänliga Hälsningar ------------------------------------------------------------------------------- Karli Sjöberg Swedish University of Agricultural Sciences Box 7079 (Visiting Address Kronåsvägen 8) S-750 07 Uppsala, Sweden Phone: +46-(0)18-67 15 66 karli.sjoberg(a)slu.se

[Users] qemu: too many ide bus during v2v migration
by Stefan Wendler 03 Dec '13

03 Dec '13

Hi, we're currently migrating over from esxi to ovirt. V2v is pretty smooth, up until I try to migrate a vm with more than 3 SCSI disks. The disks are exported from esxi as IDE and after the disks have been copied over, the process fails with "qemu: Too many IDE bus" Is there a practical way to fix this? Thanks for your help, Stefan

[Users] Fwd: oVirt 3.3.1 REST-API: UML for all Objects?
by Sven Kieske 03 Dec '13

03 Dec '13

Hi, as I didn't get any reply until today from the REST-API Maintainer, maybe someone on the users list knows where such a list of all objects can be obtained? See below for detailed information. Thank you! -------- Original-Nachricht -------- Betreff: oVirt 3.3.1 REST-API: UML for all Objects? Datum: Fri, 29 Nov 2013 11:07:22 +0100 Von: Sven Kieske <s.kieske(a)mittwald.de> An: mpastern(a)redhat.com Hi, you are listed as the REST-API Maintainer, so I write to you and hope you can help me. We need a description (preferred as UML, but we take anything we can get ) about all Objects which are provided through the Rest-API. We know we can call via REST-API, but it seems not all objects are reported back, e.g. if the object is not set. Example: Via GUI, you can set a description for each VM-Disk, but this does not get reported if I call this disk via REST-API. In the RHEV-API-Guide (Developers Guide) 3.2 there is no such list and browsing via gitweb was also not successful(maybe we looked in the wrong place?). Is there such a list or UML for all accessible REST-API-Objects for oVirt 3.3.1? Or are the objects which can't be seen via REST-API not implemented in the REST-API and are therefore just accessible over GUI?
