4.5.4 with Ceph only storage
by Maurice Burrows
Hey ... A long story short ... I have an existing Red Hat Virt / Gluster hyperconverged solution that I am moving away from.
I have an existing Ceph cluster that I primarily use for OpenStack and a small requirement for S3 via RGW.
I'm planning to build a new oVirt 4.5.4 cluster on RHEL9 using Ceph for all storage requirements. I've read many online articles on oVirt and Ceph, and they all seem to use the Ceph iSCSI gateway, which is now in maintenance, so I'm not real keen to commit to iSCSI.
So my question is, IS there any reason I cannot use CephFS for both hosted-engine and as a data storage domain?
I'm currently running Ceph Pacific FWIW.
Cheers

Error importing OVA on Ovirt-4.5.4 - no value for $TERM is defined
by raulmevi2＠hotmail.com
Hello,
I'm facing an issue where, in a new fresh installed Oracle OLVM - Ovirt 4.5.4, self-hosted engine with NFS shared storage.
That an .OVA file cannot be imported.
Steps to reproduce:
- Created test virtual machine in an NFS storage domain, installed it, allright working fine.
- Shutdown test VM
- Export test VM to a purposedly created directory /home/vdsm, whose owner is vdsm:kvm with full permissions.
- Export .OVA file concludes successfully and the file is created at that location
Then, in the exact same server, same datacenter.
- Rename source VM so it doesn't conflict because the same name (same result if I delete the source VM)
- try to import the .OVA. using the GUI. It finds successfully the file at the specified location and begins the procedure
-# up to a given point, it fails without more indications at the web GUI. No more info at the "events" than "Failed to import vm Test to Datacenter".
Fiddling into the logs, I was able to find in the hosted-engine VM, at /var/log/ovirt-engine/ova the log that goes by "ovirt-ova-external-data-ansible-DATE-HostFQDN-uuid.log" an error that specifiies
stdout_lines" : [ "tput: No value for $TERM and no -T specified", "tput: No value for $TERM and no -T specified", "tput: No value for $TERM and no -T specified"
I tinkered with the ansible role that calls a python script called "get_ova_data.py" (located at /usr/share/ovirt-engine/ansible-runner-service-project/project/roles-/ovirt-ova-external-data/)
I tried to define the variable TERM into null or into xterm but then it fails in another manner complaining about that variable.
By surfing the webs, it seems something calls "tput" like if it was in console mode but then it breaks.
Can I have some help with this, please?
Thanks

HE deployment on FC (fibre-channel) disk fails at 99% completed at final "hosted-engine --reinitialize-lockspace --force"

This identical to many others who have encountered this issue, yet nothing definitive has been suggested.
The entire HE deployment nearly finishes, but after the copy of the HE VM to the shared disk, shortly after that I reach the "initialize lockspace" section and the following error occurs:

I have this working with iSCSI on another storage system, but can't seem to get this to work on FC. I have read that the sector sizes could possible cause this. On my iSCSI system I have [PHY-SEC:LOG-SEC] as [512:512] but on my FC system I have [4096:512].
Hoping that someone can confirm whether this is the issue or not. Interestingly all previous "initialize lockspace" phases of the install are fine, it just appears to be this final one.

New host cannot connect to master domain

Hi,
i just installed a new host, which cannot connect to the master domain. The domain is an iscsi device on a nas, and ovirt is actually fine with it, other hosts have no problem. I'sure , I#m just overlooking something.
What I see in the log is:

The domain a15496dc-c241-4658-af9d-0dfe11783916 definitely exist, and works on other systems.
THe new host can acces the iscsi targets, and i am able to log into them.
Any one who knows, which blinder I have to remove, so I see the actual problem?
Thanks and best regards

Admin interface broken
by ovirt＠kirschke.de
Hi
i tried to migrate my ovirt engine form a centos 8 to a 9 machine. So, I made a backup, created and configured a new machine, stopped the old one, started the new one with identical network configuration, restored the backup and tried engine-setup to set up the new site, exping it to work. It did not, but I thought, no prob, I still have my old one.
Now, going back to the old mache, when logging into Admin Portal, I get error messages:
- Error while executing action: A Request to the Server failed: Type 'org.ovirt.engine.core.common.queries.QueryType' was not assignable to 'com.google.gwt.user.client.rpc.IsSerializable' and did not have a
custom field serializer. For security purposes, this type will not be deserialized.
- Error while executing query: null
Each in a Box, which I clicked away getting the messages toggeling.
After a while, the abckground of the admin Portal's dashboad is becomes visible, but remains empty, with the 'loading' spinner.
In the serverlog I only see the following exveption:
Caused by: com.google.gwt.user.client.rpc.SerializationException: Type 'org.ovirt.engine.core.common.queries.QueryType' was not assignable to 'com.google.gwt.user.client.rpc.IsSerializable' and did not have a custom field serializer. For security purposes, this type will not be deserialized.

Which , of course I do not understand, what it tries to tell me.
The VM-Portal is still reachable, and seems to work.
Has anybody had an effect like that, or, even better, an idea, what I am doing wrong and how I can fix that, or where I can look to find the main cause for the bahaviour-
Forgot to mention: Desperate, as I am, I also tried to upgrade to 4.5.7-master, which worked without any problem or warning, but the effect is still the same.
Thanks and best regards

Ovirt4.5 installation failure on Rocky 8
by 盛家杰
Hello Ovit Devs,
I am new to ovirt and am trying to install Ovirt4.5 on Rocky8 machine, and I am stuck at the first step, enable ovirt engine repo.
1. I follow the manual to do some yum repo configuration staff, with bash code in "Rocky" part , https://www.ovirt.org/download/install_on_rhel.html
# On Rocky there's an issue with centos-release-nfv package from extras
dnf install -y dnf-plugins-core
dnf config-manager --set-disabled extras
2. I try to install ovirt4.5 with "dnf install -y centos-release-ovirt45", but it fails with "unable to find a match". I find centos-release-ovirt45 is listed in extras repo and extras repo is disabled. If extras repo needs to be disabled, how can I install centos-release-ovirt45?
Any suggestions would be highly appreciated!
