Hi,
I noticed that if I create a directory in root of ISO domain and put an
image in it, you can see it in admin portal image list (listed as
"foo/bar.iso"), but mounting that iso in a VM ("change CD") fails
"Error while executing action Change CD: Drive image file could not be
found"
I can easily reproduce this behaviour in ovirt 4.2.8 and rhv 4.2.7.
Is it a bug?
Cheers,

As far as I can tell, there are no tools that creates subdirectories within
storage domains.
Did you manually upload the iso into the nfs mount creating a subdirectory
there?
I think this layout is not supported at all.

Yes, I did (sorry :-)). My ISOs are growing, and I'd like to have a
hierarchical structure.
To say the truth it was only a test, I wasn't sure to see ISOs in
subdir. But when I've seen them (correctly listed in admin portal as
"foo/bar.iso"), I'd expect to be able mount them.
I also filed a bug
(https://bugzilla.redhat.com/show_bug.cgi?id=1671046), if the answer
will be NOTABUG, I'll try with a RFE.
Thanks,
gc
TL;DR
The scenario I'm trying to implement is a DVD video store, provided by
images in ISO domain, automatically mounted on VM on demand, via a
backend python script. That's why in this case a hyerarchical structure
would be much better than a flat one.

Fair point. But I think editing ISOs directly like this was never really
supported.

ISO domains are deprecated, so my guess is it will be closed.
And storage domains aren't intended for the user to edit manually.
Perhaps the best way for you to organize is to make a few separate storage
domains for your subsets of ISOs.
windows_domain - win7.iso
windows_domain - win81.iso
el_domain - centos7.iso
el_domain - rhel7.iso
etc
Best wishes,
Greg

This could be a (partially satisfying solution), but I can have only one
storage domain for ISOs, right?
AFAIK you can have one ISO domain, one export domain and many data
domains; "engine-iso-uploader list" reports only ISO domain.

You can have only one iso domain attached (and so active) at a time. But
you can have many iso domains defined.
And the same domain can be defined across different domains
The same applies to export domains. When you select "Attach Export" button
in Computers -> Datacenters -> MyDc you get a list of defined export domain
among which to select the one to attach, in case you have more than one
defined.

Meant to be: the same iso domain can be defined across different DCs.
The same applies to export domains. When you select "Attach
Export" button
in Computers -> Datacenters -> MyDc you get a list of defined export domain
among which to select the one to attach, in case you have more than one
defined.

Correct. So the solution to use more than one ISO domain to logically
organize groups of ISOs cannot be accomplished, I'd like to see all my
ISOs at the same time.
That's why I think subfolders could be a nice enhancement for ISO
storage domains.

The confusion is that ISO Storage Domains are now deprecated. Use Data
Domains (upload ISOs *and* disks to the same Data Domain in the UI) and
make as many of them as you want :) )

Uploading Images to a Data Storage Domain
You can upload virtual disk images and ISO images to your data storage

Vdsm list iso files in subdirectories, and should be able to use them when
starting vms. I don't know about engine side, but this may be a regression
in 4.2, which made major changes in the way vm are started.
You can try to create a 4.1 cluster and see if this works there. If you
don't
need any of the features added in 4.2 cluster version, using 4.1 cluster
version may be good enough.
But note that ISO domains are deprecated and will be removed in future
versions. Mostly likely 4.4 will not have them.

I would like to hear more about this use case.
Why do you need to start a vm connected to iso file in a DVD store?
