I’ve installed new OpenNebula based server.  
Debian 10.2 + Opennebula 5.10.1  
then I’ve created 2 templates. Windows template works fine. But Debian template fails with error.

But during Debian installation there is this error.  
I believe this is somehow related to virtual drive “context” that is mounted, and I cannot disable it.
