Getting virtual machine to run from outside home network via Tailscale?

I set up a home NAS a used HP workstation I picked up. I installed OMV 7 and have been able to do most everything I am wanting.

I installed the KVM plugin and can setup a VM and run it from inside my home network. I set up Tailscale and can access OMV but the VM won't run. What else do I need to make this happen?
