Imageio Daemon not listening on port 54323
by tim-nospam＠bordemann.com 13 Oct '20

13 Oct '20

Hello. After an upgrade I am not able to upload images anymore via the ovirt ui. When testing the connection, I always get the error message "Connection to ovirt-imageio-proxy service has failed. Make sure the service is installed, configured, and ovirt-engine certificate is registered as a valid CA in the browser.". I found out that the imageio daemon doesn't listen on port 54323 anymore, so the browser can not connect to it. The daemon is configured to listen on port 54323 though: # cat /etc/ovirt-imageio/conf.d/50-engine.conf [...] [remote] port = 54323 [...] The imageio daemon has been started successfully on the engine host as well as on the other hosts. I am currently stuck, what should I do next? The ovirt version I am using is 4.4. There is one machine running the ovirt engine and there are 2 additional hosts. The OS on the machines is Centos 8. Thank you, Tim

Upgrade oVirt Host from 4.4.0 to 4.4.2 fails
by Erez Zarum 13 Oct '20

13 Oct '20

Hey, Bunch of hosts installed from oVirt Node Image, i have upgraded the self-hosted Engine successfully. I have ran Check Upgrade on one of the hosts and it was entitled for an upgrade. I use the UI to let it Upgrade, after multiple retries it always fails on "Prepare NGN host for upgrade." so i chose another host as a test. I have set the Host into Maintenance and let all the VMs migrate successfully. made sure i do have the latest 4.4.2 repo (it was 4.4.0) yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm And issued "dnf upgrade" Installing: ovirt-openvswitch replacing openvswitch.x86_64 2.11.1-5.el8 ovirt-openvswitch-ovn replacing ovn.x86_64 2.11.1-5.el8 ovirt-openvswitch-ovn-host replacing ovn-host.x86_64 2.11.1-5.el8 ovirt-python-openvswitch replacing python3-openvswitch.x86_64 2.11.1-5.el8 Upgrading: ovirt-node-ng-image-update-placeholder Installing dependencies: openvswitch2.11 ovirt-openvswitch-ovn-common ovn2.11 ovn2.11-host python3-openvswitch2.11 Installing weak dependencies: network-scripts-openvswitch network-scripts-openvswitch2.11 It was very quick, but nothing else happened, I did try to reboot the host but I still see the host as oVirt 4.4.0 and as expected it still says that an update is available.

Ovirt 4.4/ Centos 8 issue with nfs?
by lee.hanel＠gmail.com 13 Oct '20

Greetings, I'm trying to upgrade from 4.3 to 4.4. When trying to mount the original nfs items, I'm getting the following error: vdsm.storage.exception.StorageServerAccessPermissionError: Permission settings on the specified path do not allow access to the storage.

Does anyone have any ideas? Thanks, Lee

VM reboot cause SERVER reboot (oVirt 4.4.2)
by luigi.voso＠convergenze.it 12 Oct '20

12 Oct '20

Hi all, I've a SUPERMICRO server with a M10 GPU (at the moment i've a free-trial license) and i'm using oVirt 4.4.2. My issue is very strange and it seems to be a bug because i can reproduce it: 1. Create a VM (i've tested on Win10Pro/WinServer2012R2) with a vGPU and install the driver (without driver installed, this issue does not appear); 2. Restart the VM. At this point the physical server restarts. Instead, when i shutdown the windows vm, this issue is not appear. I've also tried with a centos 8 vm and it works very well (no reboot). All NVIDIA driver's are update at the 2020-09-30 latest release (11.0). All windows driver are installed (virtio-win-0.1.189). The VM works very well and the vGPU too. This is my very first test with vGPU and i can't understand the reason of this issue. NVIDIA enterprise support told me that it's an ovirt problem, because Windows guest operating system are supported only under Red Hat subscription programs. Has anyone else had the same problem or can you help me? Thank you in advance

oVirt 4.4 - HA Proxy Fencing
by Jeremey Wise 11 Oct '20

11 Oct '20

I have a pair of nodes which service DNS / NTP / FTP / AD /Kerberos / IPLB etc.. ns01, ns02 These two "infrastructure VMs have HA Proxy and pacemaker and I have set to have "HA" within ovirt and node affinity. But.. within HAProxy, the nodes use to be able to call the STONITH function of KVM to reset a node if / as needed. Fence Device: "stonith:fence_virsh" But with oVirt this function no longer works. For VMs and other applications which need STONITH functions, how would this be done with oVirt. I would assume the call would be to oVirt-Engine now, but not seeing documentation on HA-Proxy / Pacemaker to use oVirt. Can someone point me in the right direction? -- penguinpages
