Hello,

I'm with oVirt 4.2.3 (upgraded from 4.1 and compatibilities set to 4.2)

I have a CentOS 7 VM.

I correctly uploaded an iSO image to the disks of a data storage domain (iSCSI).

Now in web admin portal I select the VM, then the 3 dots in top right, then change cd

I'm proposed with the [Eject] line and into the dropdown I see the two iso images I have uploaded up to now.

I select an image and then OK

I get a window with title "Operation canceled" and content

Error while executing action Change CD: Drive image file could not be found

Do I have to edit any setting in my VM to be able to connect an ISO image this way?

Or other things to check?

In engine.log I have:
