[ovirt-users] Re: Booting VMs from RHEL ISOs fail
More details here:
I just tested this (new) VM now on a CentOS 7 ISO.
That worked perfectly fine.
But as soon as I tried to attach the RHEL 8 Boot ISO, it did not work.
The specific error I'm seeing is:
Boot failed: Could not read from CDROM (code 0095).
See below screenshot:

I uploaded the RHEL ISOs the same way I uploaded the Ubuntu ISOs:
Navigate to Storage -> Disks and click Upload (so using the wizard).
Once the ISOs are in place, I've attached them to VMs the same
way I've attached Ubuntu ISOs: Select the Virtual Machine, click Edit, go to Boot
Options, click the checkbox beside "Attach CD" and change the First Device to
CD-ROM.
The oVirt Manager is 4.4.6, but the cluster compatibility is stuck at
4.4.5 right now.
This particular problem has been ongoing, though, since before I attempted to upgrade
everything to 4.4.6.
