Create virt-manager instance from ReaR recovery Iso: not a bootable disk

Latest response

OS version: Redhat Enterprise 8.3
virt-manager version: 2.2.1

Recovery on new virt-manager instance was successful but on reboot there was the following message:
Booting from hard Disk...
Boot failed: not a bootable disk

Analysis of XML files looks good as I compared values with other similar resolved cases posted involving the same boot error message.

The same problem is happening with Boxes (State of the art Virtualization) so I must assume it’s a general problem with using ReaR recovery iso image in a virtual instance.

Has anyone tried to boot and recover an ReaR iso image using a virt-manager instance with any success?

Note: xml copy paste as seen below looks cut off and jumbled when viewing but when I edit post I can see the complete file and it’s well formatted?
