Description Greg Sheremeta 2019-02-06 15:22:21 UTC

Description of problem:
[RFE][UX] provide an indication in Admin Portal that ISO domains are deprecated and Data Domains can and should now store ISOs

I have had conversations with several users on the users list and Twitter that had no idea ISO domains were deprecated, or that they could / should upload ISOs to their Data Domains.

We should:
1. on creation of an ISO domain, warn the user that they probably don't need an ISO domain and should use a Data domain
2. on the disks upload page, point out that ISOs work too

Version-Release number of selected component (if applicable):
4.3

Sounds reasonable.
I guess when creating a VM, in the CDROM images dropdown menu, there will be VM disks also ?
Can't we just recreate the iso domain as data domain and somehow mark the isos , so they can be filtered during VM deployment ?

In VM Portal, you only see the ISOs.
Should be the same in Admin Portal but I haven't tried it. Please do and let me know if it doesn't work as expected.

Yes, you can create a Data Domain, and use either the UI or this tool: https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/upload_disk.py
and like I said, the filtering in the UI should just work.

Indeed, Admin Portal also properly filters the list of ISOs.

When you upload ISO file, it is stored in the data domain with ISO content
type so the system will list this image in the same way ISO files on ISO
storage domain are listed.

The main advantage is being able to use iSCSI of FC storage for ISO domain,
instead of NFS.

ISO domain have some limits that data domains do not have, and special code
for handling it. Creating a data domain as ISO domain will not help to avoid
this unneeded complexity.

I agree with Greg that we should change the UI to warn about using ISO domain
and suggest to use disk upload instead.

Comment 5 Strahil Nikolov 2019-09-28 07:14:00 UTC

Also,

We should consider a deprecation message  is  printed out during usage of engine-iso-uploader.

Comment 6 Michal Skrivanek 2020-06-23 12:35:01 UTC

This request is not currently committed to 4.4.z, moving it to 4.5

Comment 7 Bella Khizgiyaev 2021-04-26 12:30:50 UTC

An info message was added when the ISO domain is created about the domain being deprecated.

Steps to check:
1. from the domain window -> new domain -> content type ISO
2. after pressing OK a confirmation window should pop up with the info messege.
3. should work for all supported storage types under ISO.
