Dedicated Migration Network
by Clint Boggio
Good Day All;
I am in the process of assembling a new oVirt cluster and I am wondering if there is any benefit to having a dedicated set of nics solely dedicated to VM migration. If so, would those nics (bonded) be on their own vlan and subnet or would they share a subnet with gluster storage or the management network ? Right now i'm planning on the following architecture.
1. Management = 10G X2 Bond per hypervisor host (10.66.0.0/24)
2. Gluster/iSCSI Storage = 10G X2 Bond per hypervisor host (10.244.0.0/24)
3. VM Production Network(s) = 10G X2 Bond per hypervisor host (No IP Range)
4. ?? Possible Dedicated VM Migration
Thank you very much as any input would be greatly appreciated

"Retrieval of iSCSI targets failed" during hosted engine deployment on oVirt node 4.5
by pat＠patfruth.com
I have freshly installed ovirt node 4.5 from the iso download here;

During the hosted engine deployment process, I get thru Step 3 ( the "Prepare VM" step) successfully.
On Step 4 (Storage Settings), I set;
- Storage type = iSCSI
- Portal IP address = my ISCSI target's ip address
- Accept the default Portal port number, which is already set to 3260
- Leave username & password blank (as I have no CHAP configured on the ISCSI target system)
When I click the "Retrieve Target List" button there is a brief pause, followed by red error message which says "Retrieval of iSCSI targets failed"
Upon reviewing the files in /var/log/ovirt-hosted-engine-setup on the ovirt node, I find a new log file named ovirt-hosted-engine-setup-ansible-iscsi_discover-20220614084053-in517x.log

The error suggest that the iSCSI portal port number (which is defaulted to 3260 in the UI) is not being properly passed into the python module ovirt/ovirt/plugins/modules/ovirt_host.py
Looking at the code at line 638 of ovirt_host.py, found here;
https://github.com/oVirt/ovirt-ansible-collection/blob/2.0.3-1/plugins/mo...
I see;

I'm not a Python expert, so I can't tell if this logic is correct or not.
Looking at Git history on this code, it looks like the last time a change was made effecting ISCSI was in May of 2021;

I gotta believe I'm not the first one to try setting up oVirt 4.5 hosted engine with ISCSI storage.
Is anyone else out there using ISCSI storage with oVirt 4.5.0.3 yet?
How did you get it working?

Issue adding host to ovirt 4.4 cluster
by David Johnson
Good morning all,
I am attempting to add a host to my ovirt 4.4 cluster. The installation of
the first host went smoothly, but the installation of the second host
stalled.
Currently, the second host is in Installing state, but doing nothing. The
installation failed due to a failure to register the host certificate.
I cannot change the state of the host or retry the installation to capture
logs.
Warnings from the host that are visible on the ovirt console are:
- Power Management is not configured for this Host. Enable Power
Management
- Host has no default route.
- The host CPU does not match the Cluster CPU Type and is running in a
degraded mode. It is missing the following CPU flags: vmx,
model_Cascadelake-Server-noTSX. Please update the host CPU microcode or
change the Cluster CPU Type.
The error message generated at the last attempt to install the host from
the ovirt console is:
- Failed to enroll certificate for host ovirt-host-04 (User:
admin@internal-authz).
Please advise

Re: oVirt 4.4.x step-by-step procedure to renew expired oVirt certificates

both are okay, in case of a host in "up" status, it will go down during
the playbook execution, but vms will continue to run without any
downtime. Host will recover and go up once certificates will be
successfully renewed.
This is an emergency procedure, the best solution to renew a certificate
on a running host is to put the host into maintenance and renew certs
via UI.

After attaching the Storage domain, the VMs are disappeared from the VM import
by aminur.rahman＠iongroup.com
Hi,
We're noticing some weird issue while re-attaching the storage domain. After re-attach the storage domain, some VMs are completely missing from the VM Import. Before detaching the storage domain, all the VMs were shutdown gracefully.
I also noticed some disks are exists with no Alias under the disk import on the storage domain and I can't import those disks. Its failed to register the disk with <UNKONOWN> error.
We're using Ovirt 4.2 with multiple Dell hosts in the cluster and Compellent SAN with iSCSI volumes.
Please kindly advise if I am missing anything before detach the storage domain.
Thanks

The he_fqdn proposed for the engine VM resolves on this host
by khznm 21
Installing oVirt is not so easy as stated, i am struck up in FQDN resolution , i have this FQDN (vmanager.headache.com) resolve to ip 10.1.1.6 in DNS within the network,additionally i also input this entries into /etc/hosts file. while installing ( may be 8 times ) ,i am struck up with error " he_fqdn proposed for the engine VM resolves on this host " . The network is using vlan ip, the host is already installed bare metal into cisco c240-m5 with RH virtualization ver 4.4 ,its installed on IP :10.1.1.5. the problem is with installing the self hosted engine (ovirt).
the vlan are like eno2.vlan7 and eno2.vlan7.1
/etc/hosts
10.1.1.6 vmanager.headache.com vmanager
10.1.1.5 vhrh1.headache.com vhrh1
10.1.1.6 vmanager.headache.com
10.1.1.5 vhrh1.headache.com
i even tried cli install,,here also the same issue .. below are the error ..
Host name is not valid: vmanager.headache.com resolves to 10.1.1.6
Host name is not valid: vman.headache.com did not resolve into an IP address
Pls any body help here ,,,what i am doing wrong...
