Re: [Users] VM with stateless snapshot won't start

Hello Dafna, > If a failure happened and the stateless vm has shut down without delete > of the snapshot, the next time you will try to run it we will try to > delete the snapshot. > from the engine log, it seems that there is a problem deleting the > snapshot because of quota. > can you please try to disable the quota and try to run the vm again? Quota were not enabled on this Data Center, I have never done anything with quota on oVirt. The 'quota' table was empty, and the 'quota_id' field on all VMs in the 'vm_static' table was NULL. Since it was seemingly trying to set the quota_id for this particular VM to '00000000-0000-0000-0000-000000000000', I manually inserted a record into the quota table using this ID. After that, I was able to start te VM. The quota_id field for the VM now contains a reference to this fake id. > Please note that the first time you will run it after disabling the > quota, the snapshot should be deleted but the vm will still not start. > only after the snapshot is deleted you will be able to run the vm again. Indeed, it took two attempts to start the VM. Question: is it harmful to leave the fake quota record with id '00000000-0000-0000-0000-000000000000' and the reference to it in the vm_static table in place?

After a restart of Engine, the message that I got was different, something about no host being available with enough memory (which was correct). So I guess an Engine restart fixed it, even though the initial migration task still shows as unfinished in the Tasks panel. Cheers, Martijn.

[Users] Failing migration, inconsistent state
by Martijn Grendelman 05 Dec '13

05 Dec '13

Hi, I tried to migrate several VMs from one host to another. Two VMs migrated without issues, but for one VM, the migration didn't happen. It seems to be hanging, but the UI is now in an inconsistent state: - The 'Tasks' tab reports 0 active tasks, but the last task (the migration in question) is still reported as 'Executing'. - The VM status is 'Up' (not migrating) - 'Migrate' action is choosable from menu, while 'Cancel Migration' is greyed out, but when I choose 'Migrate' and pick a host, I am told 'Cannot migrate VM. VM <name> is being migrated.'. What is the best way to fix this? Met vriendelijke groet, Martijn Grendelman

[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.

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 <div class="moz-signature">-- <div id="oernii_footer" style="color: gray;"> Ernest Beinrohr, AXON PRO DevOps, <a style="text-decoration: none; color: gray;" href="http://www.beinrohr.sk/ing.php">Ing</a>, <a style="text-decoration: none; color: gray;" href="http://www.beinrohr.sk/rhce.php">RHCE</a>, <a style="text-decoration: none; color: gray;" href="http://www.beinrohr.sk/rhce.php">RHCVA</a>, <a style="text-decoration: none; color: gray;" href="http://www.beinrohr.sk/lpic.php">LPIC</a>, <a style="text-decoration: none; color: gray;" href="http://www.beinrohr.sk/vca.php">VCA</a>, <a style="text-decoration: none; color: gray;" href="callto://+421-2--6241-0360">+421-2--6241-0360</a>, <a style="text-decoration: none; color: gray;" href="callto://+421-903--482-603">+421-903--482-603</a> icq:28153343, <a style="text-decoration: none; color: gray;" href="callto://oernii-work">skype:oernii-work</a>, <a class="moz-txt-link-abbreviated" href="mailto:jabber:oernii@jabber.org">jabber:oernii@jabber.org</a> <hr style="height: 1px; width: 95%"> For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled.
