The only reason I can think of that prevents using the cloud-init options in 3.3 is that the operating system isn't defined as a Linux variant. Select the VM, click the "Edit" button and make sure to select a Linux operating system in the "Operating System" list. The closer to the actual operating system the better. Then try again "Run Once". To avoid making this for every VM you create, you should do the change in the template as well. By the way, please reply to the list, there may be other people interested in your same issue. -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif.

[Users] Python SDK - VNIC profiles collection is missing under root
by Genadi Chereshnya 18 Feb '14

18 Feb '14

Hi, We installed the new ovirt-engine-sdk-python from Fedora repo - version 3.3.0.7-1.fc20 The VNIC profile collection was missing under API root. Installing it from nightly (version ovirt-engine-sdk-python-3.5.0.0-1.20140211.git61ac75b.fc20.noarch) had the same result. According to changelog (http://wiki.ovirt.org/Python-sdk-changelog) it was supposed to work from 3.3.0.4-1 Last time it was working was on 3.3.3-0.1 version. Thanks, Genadi

[Users] "Volume Group does not exist". Blame device-mapper ?
by Nicolas Ecarnot 17 Feb '14

17 Feb '14

Hi, oVirt 3.3, no big issue since the recent snapshot joke, but all in all running fine. All my VM are stored in a iSCSI SAN. The VM usually are using only one or two disks (1: system, 2: data) and it is OK. Friday, I created a new LUN. Inside a VM, I linked to it via iscsiadm and successfully login to the Lun (session, automatic attach on boot, read, write) : nice. Then after detaching it and shuting down the MV, and for the first time, I tried to make use of the feature "direct attach" to attach the disk directly from oVirt, login the session via oVirt. I connected nice and I saw the disk appear in my VM as /dev/sda or whatever. I was able to mount it, read and write. Then disaster stoke all this : many nodes suddenly began to become unresponsive, quickly migrating their VM to the remaining nodes. Hopefully, the migrations ran fine and I lost no VM nor downtime, but I had to reboot every concerned node (other actions failed). In the failing nodes, /var/log/messages showed the log you can read in the end of this message. I first get device-mapper warnings, then the host unable to collaborate with the logical volumes. The 3 volumes are the three main storage domains, perfectly up and running where I store my oVirt VMs. My reflexions : - I'm not sure device-mapper is to blame. I frequently see device mapper complaining and nothing is getting worse (not oVirt specifically) - I have not change my network settings for months (bonding, linking...) The only new factor is the usage of direct attach LUN. - This morning I was able to reproduce the bug, just by trying again this attachement, and booting the VM. No mounting of the LUN, just VM booting, waiting, and this is enough to crash oVirt. - when the disaster happens, usually, amongst the nodes, only three nodes gets stroke, the only one that run VMs. Obviously, after migration, different nodes are hosting the VMs, and those new nodes are the one that then get stroke. This is quite reproductible. And frightening.

[Users] Command line : how to add a removed host?
by Nicolas Ecarnot 17 Feb '14

Hi, Doing some tests, I set 2 hosts into maintenance mode, then "removed" them. When trying to add them back into the cluster, I found nothing more than the "new" action. Using it and configuring the IP address, I see oVirt re-installing many packages. Once installed, the host can not be added because : "Host host016 is installed with VDSM version (4.13) and cannot join cluster cluster21 which is compatible with VDSM versions [4.9, 4.11, 4.12, 4.10]." In fact, I have 2 questions: - For the second host (still untouched), is there a way to add it back into the cluster without re-installing the packages maybe via the command line) (and then preventing this version issue)? - For the weeks to come, I see I'll have to upgrade some parts. I don't know what is needed to upgrade for the VDSM version to get upgraded ("for [4.9, 4.11, 4.12, 4.10] to increase"). Obviously, I don't want to break the whole cluster while upgrading it. Thank you. -- Nicolas Ecarnot
