I have installed KVM Hypervisor and KVM tools using yast. Using vir-manager, installed a guest all worked, however when I started the guest the next time I get this message

Code:
Booting from DVD/CD
Boot Failed Could not read from cdrom(code 0003)
No Bootable device
In the boot options there are only two options the CDROM or the Nic.


Having read the documentation I discover that you can install "Import from existing image" option. I did that and now I get this error message.
Code:
(initramfs) Unable to find a medium containing a live system
What have I missed?

Thank you for your help
