Hmmm, I would expect that to work. There are expected consequences of moving the VM between machines — it changes the provisioning UDID — but that shouldn’t stop it from logging in to an Apple Account.
I just tried this here in my office and I’m also having problems, although it has different symptoms that what you’ve described. I’m gonna dig into this some more and get back to you.
In the meantime, however, I wanted to share one specific piece of advice: Make sure the Apple Account you’re using has two-factor authentication enabled. Based on my previous testing, that’s a requirement.
Share and Enjoy
