[Users] oVirt 3.4 planning
by Itamar Heim 13 Nov '13

13 Nov '13

To try and improve 3.4 planning over the wiki approach in 3.3, I've placed the items i collected on users list last time into a google doc[1] now, the main thing each item needs is a requirements owner, devel owner and a testing owner (well, devel owner is really needed to make it happen, but all are important). then we need an oVirt BZ for each, and for some a feature page. I also added columns indicating if the item will require an API design review and a GUI design review. this list is just the start of course for items from it to get ownership. i expect more items will be added as well, as long as they have owners, etc. the doc is public read-only, please request read-write access to be able to edit it. feel free to ask questions, etc. Thanks, Itamar [1] http://bit.ly/17qBn6F

If it works with Nagios, it works with Icinga. Cheers, Martijn.

[Users] [QE] bug scrubing / triaging
by Sandro Bonazzola 13 Nov '13

13 Nov '13

Hi, Looking at bugzilla, there are 366 bugs without a target release. Some of them are in POST state but I'm pretty sure they should be in ON_QA or CLOSED state. A lot of them haven't a whiteboard set. Please review the bug list and help to scrub and triage them: https://bugzilla.redhat.com/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&… Thanks -- Sandro Bonazzola Better technology.

[Users] [Bug] 3.3.1. Beta Create VM does not work with VNC / Linux VM
by Sven Kieske 12 Nov '13

12 Nov '13

Hi, we just discovered a bug in ovirt-engine 3.3.1 beta from ovirt.org repo: You can't create a VM (via webadmin) with the following options: set VM-Name select Operating System: "Other Linux", "Linux", or any Linux distro click: "Show advanced options" switch: console: protocol: from SPICE to VNC Hit "Ok" receive the following error in webadmin gui: "Error while executing action: bug1: Cannot add VM. Cannot set single display device via VNC display." (bug1 is the vm-name) workaround1: select "other os" or any windows version and the setup works with vnc workaround2: select spice as protocol I created a BZ for this: https://bugzilla.redhat.com/show_bug.cgi?id=1029584 I suggest this bug as a blocker for 3.3.1. release -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Users] Live storage migration snapshot removal (fails)
by Sander Grendelman 12 Nov '13

12 Nov '13

When I move a disk (of a running vm) to a different storage pool a live snapshot ('Auto-generated for Live Storage Migration') is created. The allocation type of the virtual disk changes from "Preallocated" to "Thin Provision" with actual size > virtual size (e.g. 4GB actual, 1GB virtual). This snapshot is not removed after the storage migration is completed and cannot be removed from a running VM ( probably because live snapshot deletion is not implemented yet?). When I stop the VM and then remove the snapshot this fails and the snapshot state changes to "BROKEN". I've done some additional testing and the problem only occurs when a preallocated disk is used. Offline snapshot removal on a thin provisioned disk works (no online removal option). Is this expected behaviour? If so, I think live storage migration for preallocated disk should be disabled. Attached vdsm.log of the SPM host with the DEBUG and INFO lines removed to get it down to a manageable size.

[Users] Default route on hosts
by Assaf Muller 12 Nov '13

12 Nov '13

Hi Christopher, Your understanding of the terms is correct. A small clarification - Hosts are mostly referred to as nodes when running oVirt Node, a custom Linux distribution purposely made to be used as a host in oVirt. As for your question: DEFROUTE=yes/no in the hosts' ifcfg files control the default gateway of the host. Currently, by design, the management network's gateway (Which sounds like your management network doesn't have?) will be kept as the host's default gateway. This was done to make sure that the engine maintains connectivity to its hosts. oVirt 3.3 introduced a feature called multiple gateways which may assist you. If you configured a gateway on the public network (Either statically via oVirt or via DHCP), then all traffic into the hosts through their public network NIC will be returned via that nic, *even though* the host's default gateway is ovirtmgmt's gateway. To clarify further: The current behavior is that the host's default gateway is ovirtmgmt's gateway. This controls traffic originating from *within* the host such as communications with storage. Incoming traffic, however, such as traffic originating from users from outside of the datacenter, will be returned via the device that the traffic came in on. If that doesn't work for you, and you feel like you need to control the host's default gateway via oVirt, then please file an RFE. I can't guarantee a timeline or that it will ultimately make it in the product, but the RFE will be carefully taken into account when designing future versions. ----- Original Message ----- From: "Christopher Geddings" <chris.geddings(a)duke.edu> To: users(a)ovirt.org Sent: Monday, November 11, 2013 8:40:33 PM Subject: [Users] Default route on hosts Before I ask my question, I want to make sure I'm using the right terms: engine == the system that manages the ovirt environment.

Hi guys, sharing some updates on oVirt UI plugins feature, see below for details. Let me know if you have any questions. Vojtech ----- Forwarded Message ----- From: "Vojtech Szocs" <vszocs(a)redhat.com> To: "engine-devel" <engine-devel(a)ovirt.org> Cc: "Einav Cohen" <ecohen(a)redhat.com>, "Itamar Heim" <iheim(a)redhat.com> Sent: Thursday, November 7, 2013 11:21:21 PM Subject: oVirt UI plugins feature announcements Hello everyone, I'd like to share some important updates on oVirt UI plugins feature. First of all, UI plugins wiki [1] is finally complete. API reference (application events, API functions, API options, entity types) now includes all the details and snippets of example code. I've also added section "Why load plugins via iframe element?" explaining reasons behind this design decision. [1] http://www.ovirt.org/Features/UIPlugins You might have noticed the changes in oVirt Engine URI layout [2], these are already reflected in UI plugins wiki. For existing plugins, this means changing URLs like this: /webadmin/webadmin/plugin/ExamplePlugin/start.html to this: /ovirt-engine/webadmin/plugin/ExamplePlugin/start.html [2] http://gerrit.ovirt.org/#/c/20473/ We're planning to merge patch "Improve UI Plugin vs. REST API integration" [http://gerrit.ovirt.org/#/c/20404/] soon, please review the change outlined in commit message, let me know if you have any questions. Last but not least, oVirt Space Shooter (a.k.a UI plugins crash course) wiki [3] has been updated to reflect changes mentioned above.
