Maximum domains per data center
by Tommaso - Shellrent
Hi to all.
Can someone confirm to me the value of max domains per data center on
ovirt 4.4 ?
We found only this for RHEV: https://access.redhat.com/articles/906543

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:

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

oVirt 4.4 - HA Proxy Fencing
by Jeremey Wise
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?

Fencing with oVirt 4.4 apc master switch
by Jeremey Wise
I use to have hand built CentOS+KVM + Gluster.
Moved to HCI oVirt controlled system and so far, been very happy with
stability and quality.
One feature that was working in old "hand build" version was fencing.
I have an old APC master switch AP9606. I use to have and use it for
master switch functions of nodes but sense replacement with oVirt it has
not worked. Here are setup notes and symptoms
IP: 172.16.100.2
Username: apc
Password: <blah>
Port 8 (it is an eight port unit)
Slot: <empty as I have no idea what is expects here I also input values
here but no change>
Error:
Test failed: WARNING:root:Parse error: Ignoring option 'agent' because it
does not have value ERROR:root:Unable to connect/login to fencing device
2020-10-11 11:28:50,885 ERROR: Unable to connect/login to fencing device
Questions:
1) Has anyone setup this with oVirt such that it uses apc master switch
2) Where is oVirt putting these logs / running this service. I assumed
oVirt engine running the services and so tried to find details and logs
here.
