Using the web-ui VM portal through a proxy failing
by Callum Smith 15 Feb '19

15 Feb '19

Dear oVirt Gurus, Using the oVirt user VM portal seems to not work through the squid proxy setup (configured as per the guide). The page loads and login works fine through the proxy, but the asynchronous requests just hang. I've attached a screenshot, but you can see the "api" endpoint just hanging in a web inspector: "https://proxyfqdn/ovirt-engine/api/" [cid:CA42E493-3AD9-45F8-B4C3-C914F059390C@well.ox.ac.uk] This works fine when not going through the proxy. Is there a way to force noVNC HTML as the console mode through the web-ui, or at least have it as an option if not default? The console seems not to work when logged in with a base 'user role'.

Create Snapshots on Windows 7 Pro x64 VM's causes Bootload errors
by robertodg＠prismatelecomtesting.com 15 Feb '19

15 Feb '19

Hello everyone, on Ovirt 4.2.6.4-1.el7, when we try to create a snapshot on Windows 7 Pro x64 (regardless of whether the VM is powered off or not) after several reboots it causes bootload errors (below you'll find a link with screenshoot error). https://ibb.co/tKx6SKw We haven't tried other Windows versions yet, do you have any idea about what the cause might be? Thanks in advance.

Ovirt self-hosted engine won't come up
by joshuaosko＠gmail.com 14 Feb '19

14 Feb '19

The self-hosted engine had an issue whereby it'd /var partition was full. A few days later the engine was rebooted; however, it did not come back up gracefully. I presently have three CentOS 7 hosts which can spin up a new hosted engine vm; however every attempt to do so results in: Engine status : {"reason": "failed liveliness check", "health": "bad", "vm": "up", "detail": "Up"} The VM is not "up" as it does not even respond to ping, let alone having any ability to ssh or console into it to see what's wrong. All of the VMs that have been built using this engine appear to be fully operational. Is there any guidance anyone can give me? At this point I'm wondering what the consequences are to deploying a new hosted engine within that same cluster. If anyone could shed light on this matter it would be tremendously appreciated! Thanks.

please help with console issues on vGPU enabled VMs.
by Edward Berger 14 Feb '19

14 Feb '19

We are attempting to get vGPU-enabled guests working with our oVirt 4.3.0 configuration, but have run into problems. We are running: NVidia License Server version 2018.09 NVidia License Client Manager 2018.10.0.25098346 and that license info is correctly retrieved by the clients. With a Centos 7.6 guest, we can ssh into the guest and see that the X server is running and a gdm process is also running, but when we open a remote console viewer, all we get is a black screen. The X server reports the correct vGPU profile. The only error we see in the Xorg.0.log file is: [ 5.176] (EE) NVIDIA(GPU-0): Failed to update the GLS device with FRL configuration but that is not fatal. With a Windows 10 guest, we do get a login screen to appear, but the mouse and keyboard do not seem to be functional. Host configuration: host is running oVirt-node 4.3.0 NVidia driver NVIDIA-vGPU-rhel-7.6-410.91.x86_64.rpm installed CentOS 7.6 guest configuration: NVidia driver NVIDIA-Linux-x86_64-410.92-grid.run installed added an explicit BusID in the guest's xorg.conf file disabled SELinux Windows 10 guest configuration: NVidia driver 412.16_grid_win10_server2016_64bit_international.exe installed Remote viewer: remote-viewer 5.0-11.el7 running on CentOS 7.3 Both host and guest NVidia drivers come from the NVIDIA-GRID-RHEL-7.6-410.92-410.91-412.16.zip package. We have tried with both V100 and P4 GPUs (with ECC disabled), and encounter similar problems. Any ideas on what to try, or how to better diagnose the cause of these problems? Thanks.

Hi, Recently i upgrade my oVirt installation 4.2.8 to 4.3. I was able to login right after upgrade (yum, setup, reboot). But according to logs, account locks in 2-3 minutes. 2019-02-12 15:44:57,228+03 ERROR [org.ovirt.engine.core.sso.utils.SsoUtils] (default task-1) [] OAuthException invalid_grant: The provided authorization grant for the auth code has expired. 2019-02-12 15:44:57,232+03 ERROR [org.ovirt.engine.core.aaa.filters.SsoRestApiAuthFilter] (default task-2) [] Cannot authenticate using authentication Headers: invalid_grant: The provided authorization grant for the auth code has expired. 2019-02-12 15:44:57,307+03 INFO [org.ovirt.engine.extension.aaa.jdbc.core.Authentication] (default task-2) [] locking user: admin due to interval failures I was able to unlock admin using CLI, but every time i go to OVN config it locks immediately.

possibly corrupted disk during 4.3 upgrade
by Jason Brooks 14 Feb '19

14 Feb '19

I have a ovirt+gluster cluster that I've been running for a while now -- across several versions of oVirt. I was upgrading to 4.3 today, and am halfway through the upgrade. I've upgraded two of my four hosts to 4.3, as well as the engine, but the hosted-ha agents aren't running on my new hosts. Also, one of my two upgraded hosts won't connect to one of my domains -- I'm not sure whether that's the master data domain or the hosted engine domain. The *main* thing I'm concerned about, though, is that the disk for one of my large VMs appears to have been truncated -- it's virtual size is 300GB, I think the actual size was probably just under half of that, but it's actual size is now reported to be less than a gig, and it's taking up only 300MB of space. I'm afraid the answer is no, but I'm hoping that the data might be recoverable from somewhere on the bricks... Any thoughts? Jason

Re: Creating a static route
by Lev Veyde 14 Feb '19

14 Feb '19

Hi Doug, Sorry that it took a bit of time to get back to you. Managed to catch today somebody from the oVirt/RHV network team to discuss the issue. It seems that we don't currently support custom static routes on the hosts, so the workaround that I suggested is the way to do it.

Problem installing hyperconverged setup
by paul＠agile.uk.com 14 Feb '19

14 Feb '19

Hi, I am currently setting up an Ovirt cluster in a test environment and cannot get the hyperconverged setup to run properly. I have installed 3 nodes on version 4.2.8. I keep getting the following error - TASK [Create LVs with specified size for the VGs] ****************************** failed: [node01.ovirt.local] (item={u'lv': u'gluster_thinpool_sdb', u'size': u'1005GB', u'extent': u'100%FREE', u'vg': u'gluster_vg_sdb'}) => {"changed": false, "item": {"extent": "100%FREE", "lv": "gluster_thinpool_sdb", "size": "1005GB", "vg": "gluster_vg_sdb"}, "msg": " WARNING: Pool zeroing and 3.00 MiB large chunk size slows down thin provisioning.\n WARNING: Consider disabling zeroing (-Zn) or using smaller chunk size (<512.00 KiB).\n Volume group \"gluster_vg_sdb\" has insufficient free space (157261 extents): 343040 required.\n", "rc": 5} to retry, use: --limit @/tmp/tmpbXqHhw/lvcreate.retry All 3 nodes have an /sdb installed which are different sizes but all in excess of 450Gb. I have specified JBOD in the setup. I have tried reducing the size of the engine, data and vmstore bricks to 50Gb each instead of the default but the installation still fails. I think it has something to do with the thin provisioning but not sure what. Any help would be much appreciated. Thanks Paul.

Deleted Hosted Engine
by Manny SyS 14 Feb '19

14 Feb '19

I have to deal with this oVirt 4.2 cluster, 4 nodes. It seems someone smartly deleted hosted engine vm... how cool... so, all the VMs are still running, but no cluster management anymore :-). It's a testing environment, no hosted engine backup. I have no problems reinstalling the cluster... but I'd love to rescue the VMs... so I'm trying to understand what options I do have, so I ask you please if you have some hints, or maybe links to the right documentation. - ssh to any ovirt cluster node and export the vms with virsh? possible? - ssh to any ovirt cluster node and live migrate all the vms on one node? so that I can reinstall a new cluster on the freed nodes? Wondering which one is the correct path to do this... btw, virsh only works in readonly in ovirt cluster nodes - it's a testing environment, so I could shutdown everything, reinstall a new cluster, reconnect the old storage to the new cluster... question is, how to reimport all the vms in the new cluster. Please any suggestions?
