oVirt 4.4.2.6-1.el8 (SHE). Grafana integration not configured. The link to the Monitoring portal is not displayed on the Manager home page.
by Dmitry Kharlamov
Good day!
Made a fresh installation of 4.4.2 Self Hosted Engine (not an upgrade from 4.4.1) however there is no link to the Monitoring portal on the home page.
Service ovirt-engine-dwhd started and work. Grafana-server service not present in /etc/systemd and not configured.
Please tell me what needs to be done to make the monitoring portal work?
PS// In the previous version installation 4.4.1 SHE the grafana-server worked immediately after installation and the link to the monitoring portal was available immediately without any additional steps.

Imageio Daemon not listening on port 54323
by tim-nospam＠bordemann.com
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
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
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. Verify permission settings on the specified storage path.: 'path = /rhev/data-center/mnt/nfshost:nfs_path'
with the following stack trace:
2020-10-08 19:00:17,961+0000 ERROR (jsonrpc/4) [storage.HSM] Could not connect to storageServer (hsm:2421)

During handling of the above exception, another exception occurred:

File "/usr/lib/python3.6/site-packages/vdsm/storage/fileSD.py", line 93, in validateDirAccess
raise se.StorageServerAccessPermissionError(dirPath)
via an ls, it looks like there are the correct permissions:
ls -alh
total 0
drwxr-xr-x. 1 vdsm kvm 100 Oct 8 19:15 .
drwxr-xr-x. 4 vdsm kvm 115 Oct 8 19:02 ..
drwxr-xr-x. 1 vdsm kvm 52 Oct 1 20:35 ffe7b7bb-a391-42a9-9bae-480807509778
d---------. 1 vdsm kvm 22 Mar 17 2020 '#recycle'
But, I wrote a short script to check the individual permissions that are checked, and it thinks I can't write to the directory:
We can Read From it: /rhev/data-center/mnt/nfshost:nfspath
We can't write to it: /rhev/data-center/mnt/nfshost:nfspath
We can execute to it: /rhev/data-center/mnt/nfshost:nfspath
This is doing a simple:
print(os.stat(path))
if os.access(path, os.F_OK):
print("It Exists", "/rhev/data-center/mnt/nfshost:nfspath")
else:
print("It Doesn't Exists", "/rhev/data-center/mnt/nfshost:nfspath")
if os.access(path, os.R_OK):
print("We can Read From it: ", "/rhev/data-center/mnt/nfshost:nfspath")
else:
print("We can't Read from it: ", "/rhev/data-center/mnt/nfshost:nfspath")
if os.access(path, os.W_OK):
print("We can write to it: ", "/rhev/data-center/mnt/nfshost:nfspath")
else:
print("We can't write to it: ", "/rhev/data-center/mnt/nfshost:nfspath")
if os.access(path, os.X_OK):
print("We can execute to it: ", "/rhev/data-center/mnt/nfshost:nfspath")
else:
print("We can can't to it: ", "/rhev/data-center/mnt/nfshost:nfspath")
I took this same checks over to the Centos 7 host, and I it passes the checks fine.
Does anyone have any ideas?
Thanks,
Lee

VM reboot cause SERVER reboot (oVirt 4.4.2)
by luigi.voso＠convergenze.it
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
