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 message near the end of the log file are as follows;

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/modules/ovirt_host.py
I see;
.....
elif state == 'iscsidiscover':
host_id = get_id_by_name(hosts_service, module.params['name'])
iscsi_param = module.params['iscsi']
iscsi_targets = hosts_service.service(host_id).discover_iscsi(
iscsi=otypes.IscsiDetails(
port=int(iscsi_param.get('port', 3260)), <----

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;
https://github.com/oVirt/ovirt-ansible-collection/commit/1c4c18d844a69b821fba4f9d3d6561d088d726b3
By Martin Necas - https://github.com/mnecas
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?
