I have an existing FreeBSD 10.3 guest VM running under VMWare Fusion 4.1.4 on a OS X 10.8.5 Mac Mini host (C2D CPUs). It's been running fine for a few years now, and continues to do so on the somewhat ancient hardware. The FreeBSD guest doesn't run X or sound or anything like that, it's a little web development server in console mode. The guest is assigned a single CPU and 1GB of RAM.
I've set up a new OS X 10.11.5 host (on a MBP15, i7 CPUs) with VMWare Fusion 8.1.1. I copied the VM over to the new host, and tried to import it into Fusion. Oddly, after navigating to the desktop where I had the file, it was shown "greyed out" and could not be selected. So I did a File, Open and opened it that way. It asked if I had moved or copied the VM, I said copied. It then asked I wanted to upgrade the VM, I agreed.
The VM boots but is only able to run for a short period of time (perhaps a minute) before it spontaneously reboots. I've tried changing the VM hardware version from 12 back to 8 and I've tried disconnecting most of the virtual devices (such as CD, network adapter, sound, etc).
Are there any differences between Fusion 4 and 8 that I would need to account for and change configuration to prevent this from occurring?
