[Engine-devel] Floating Disks implementation in REST-API
by Ori Liel 11 Apr '12

11 Apr '12

The "Floating Disks" feature makes disks into stand-alone entities: a given disk may be attached to a VM (as all disks are today), or it may be not attached to any VM, which makes it a floating disk (http://www.ovirt.org/wiki/Features/FloatingDisk) To implement attach/detach of disk to/from VM in REST-API, we intend to introduce two new actions: POST .../api/vms/{vm:id}/disks/{disk:id}/attach POST .../api/vms/{vm:id}/disks/{disk:id}/detach Since we try not to add new actions unless we have to, I want to explain why I believe that these actions are necessary. The other implementation would use existing add/remove flows: POST .../api/vms/{vm:id}/disks - if the disk was passed with an ID, attach it to this VM. If no id - create a new disk. DELETE .../api/vms/{vm:id}/disks/{disk:id} - *ambiguity problem, need to add a flag* We can't break existing API, so regular DELETE must remove the disk, as it does today. To detach a disk using DELETE we'd have to add a flag to the DETELE command. This is quite risky, because if the user forgets to pass this flag, the disk which he wanted to detach will actually be deleted. Theoretically, if we could break the API, the following modelling would resolve the ambiguity and perhaps be ideal: - POST/DELETE disk in root context means create or delete it. - POST/DELETE disk in VM context means attach or detach it. But we don't have the privilege of breaking the API. Considering all of the above - and the fact that attach/detach nics to/from host is also implemented using actions - I believe that the new actions are justifiable. Any comments? Thanks, Ori

[Engine-devel] Problem with detachment of host interface using ovirt-sdk

Once the network is attached to the interface I try to detach the network f= rom the interface using the following steps: 1.Detach the network from the cluster through the GUI. 2.Remove the network from the datacenter through the GUI. 3.Detach the network from the host's interface using the SDK: nic =3D api.hosts.get(name=3Dhost).nics.get(name=3Dif_name) net =3D params.Network(name=3Dnet_name) act =3D params.Action(network=3Dnet) nic.detach(act) api.hosts.get(name=3Dhost).commitnetconfig() Then I get the error: http://pastebin.com/3Md07huE The same flow using the GUI works fine. Network removal from the Datacenter is a trigger for me to run the detachme= nt operation therefore I use this flow. I use the following components: rhevm-3.0.2_0001-2 ovirt-sdk (Using the latest from git repository) Please advise how to proceed.

[Engine-devel] "add permission to user" dialog - nothing shown by default
by Einav Cohen 11 Apr '12

11 Apr '12

[https://bugzilla.redhat.com/show_bug.cgi?id=810287] When opening the "add permission to user" dialog, no user is shown in the grid by default; user has to enter something in the search text-box within the dialog (or leave it empty) and hit "Go"; only then the list of users is being filled (according to the search text-box contents). This behavior is by design. Do you think that this behavior should change? i.e. do you think that the users grid should be filled right after opening the dialog with a list of all users? Please consider the following: - calling to the search query and rendering its results may take a while, so user may open the dialog, but will be able to do something only after waiting a while (when originally, all he intended to do was to search a very particular user, which would have taken a short time). - we may have several domains, so grid will be filled with results of the first domain selected (which might not be the domain that the user intended to search originally), so this may be annoying. Due to the reasons above, my personal take is that the current behavior is OK and shouldn't be changed (i.e. BZ should be closed). Any comments?

[Engine-devel] VM Payload feature
by Oved Ourfalli 10 Apr '12

10 Apr '12

Hey all, Continuing the discussion about Aeolus instance data injection to a VM (http://lists.ovirt.org/pipermail/engine-devel/2012-January/000423.html) we propose a new VM Payload feature. The following wiki page contains a description page of the feature. http://www.ovirt.org/wiki/Features/VMPayload Please read and review. There are several approaches there, and we wish to head your opinions and thoughts about them. Once we agree on an approach, we will start designing. Thank you, Oved

[Engine-devel] Is there a preferred workflow when adding additional error messages to VDSM _and_ Engine?
by Lee Yarwood 10 Apr '12

10 Apr '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello all, I'm currently working on a patch to correct the logic used by vdsm when reviewing the logical and physical block size of physical volumes [1]. Once/If this is approved I'd like to look into making the exceptions thrown from vdsm and the errors displayed within engine more descriptive. Before I start throwing patches into gerrit I was wondering *if* there is a preferred workflow when adding additional exceptions and error messages across both projects. For example, committing changes to vdsm before engine, engine before vdsm or both at the same time. I'm also wondering if there is a way to say that vdsm gerrit changeid x relies on engine gerrit changeid y etc?

[Engine-devel] deprecating auto-detection of Ldap provider types
by Roy Golan 09 Apr '12

09 Apr '12

auto-detection featured few bugs lately which convinced me that it must be deprecated/removed from the code in favor of adding manual set of the provider type. main reasons for that: a. the provider is type is known by the user b. identifying a provider by the rootDSE attributes is error-prone, not reliable etc... specially if the support matrix is growing c. auto-detection logic is duplicated (and not shared) between the backend code and the manage-domains tool (nevermind the reasons now) A manual set of the provider type requires a new configuration field for a domain and the question is the upgrade path which may look like * set the provider type to default Active Directory (because its more likely to be the provider type) * things not working - use the engine-manage-domains and choose the provider type. * optionally - keep the auto-detection (of the tool only!) if user wants to use it. your suggestion and thoughts... Thanks, Roy
