Hello everyone, Please excuse me if this question has been asked before, I've searched the mailing list archives and can't find someone having the same problem as I am. I have a new oVirt installation that I'm trying to configure, and I cannot get the ISO domain I configured during engine-setup to show in the UI at all. Installation layout: # Engine CentOS 7 - oVirt Engine 3.5 (VM on different, non-oVirt cluster) # Nodes de-fra-p-hv05 - oVirt Node 3.5 de-fra-p-hv06 - oVirt Node 3.5 I installed and configured the engine, but the node that runs the engine is a VM, and will not be running VMs itself. I intend to use it only as a management node (in the VMWare world this would be analogous to the vCenter server). I don't want to run hosted engine because that requires me to install Fedora/CentOS on the blades. I would much rather have the engine live on a different cluster and just run oVirt node on the blades. I am able to install the nodes successfully, and configure them from within the engine UI. I am using an iSCSI SAN for VM storage. As per the Quick Setup guide, I have configured my iSCSI network on the nodes and created an iSCSI storage domain for VMs. Where I am utterly stuck is the creation of the ISO domain: http://www.ovirt.org/documentation/quickstart/quickstart-guide/#Attach_an_IS... Since the server running oVirt engine is not participating in the cluster, it doesn't appear in my data center. This might be my problem, but I'm not sure. Here's a summary of the data center I have configured thus far: System |- Data Centers |- Default |- Storage |- sanQA |- Networks |- ovirtmgmt |- hpmsa |- vmnet128 |- Clusters |- QA |- Hosts |- de-fra-p-hv05 |- de-fra-p-hv06 I have edited the ACL on the server running oVirt engine to allow rw access on /var/lib/exports/iso to nodes de-fra-p-hv05 and de-fra-p-hv06. $ cat /etc/exports.d/ovirt-engine-iso-domain.exports /var/lib/exports/iso de-fra-p-ove01.domain.xyz(rw) /var/lib/exports/iso 172.20.102.215(rw) /var/lib/exports/iso 172.20.102.216(rw) When I try to import an ISO domain in the Data Center -> Storage tab, I get the following error: "Error while executing action: Cannot add Storage Connection. Storage connection already exists." Attached is the engine log from attempting to import the ISO domain. I don't have any ISO domain visible in the Storage tab of my data center. Since I cannot see the ISO domain in the UI, I cannot create new virtual machines on my cluster. Please help me understand what I've done wrong. I've also attached a screenshot of the management interface. As you can see, I've configured an iSCSI domain. I see no button in the UI to "Attach ISO" http://www.ovirt.org/documentation/quickstart/quickstart-guide/#Attach_an_IS... Thank you, Hal

Import ISO domain? I think you want to attach it, not import it.
I don't have any ISO domain visible in the Storage tab of my data center. Since I cannot see the ISO domain in the UI, I cannot create new virtual machines on my cluster.
Please help me understand what I've done wrong.
I've also attached a screenshot of the management interface. As you can see, I've configured an iSCSI domain. I see no button in the UI to "Attach ISO"
You should see the button if you open the correct tab: 1. On the left pane, click the data center name (Frankfurt) 2. Select the "Data Centers" tab in the top right 3. Select the "Storage" tab in the bottom You should see the "Attach ISO" button in the top of the Storage tab. See the attached screenshot (from 3.6, but it should be similar) Nir

Hi Nir, Thanks for the tip, I didn't think to look there. The oVirt GUI isn't the most intuitive... I now have the ISO domain attached to the data center. -Hal On Fri, Mar 18, 2016 at 9:02 PM, Nir Soffer <nsoffer@redhat.com> wrote:
