Importing Virtual Box into Fusion 12 difficulties

HI all,

Having some difficulties importing a VM from VirtualBox into Fusion 12. First attempt with an Open format v2 export failed on import. Second attempt with a v1 .ova format is progressing. The import halted and prompt to attempt a retry with a lower HW standard I believe the message said. Does anyone know a better way to import a Virtual Box VM into Fusion 12? The VM is an Ubuntu 20.04 LTS Desktop that I use to run my house Wireless AP Controllers and Homebridge.

Thanks
