APFS in Fusion 10.x

[TECH198]

Will there be an option to include APFS in Guests High Sierra onwards?

I know currently Fusion uses virtual image HD, but it could support APFS culdn't it being virtual?

Apple probably would be against using it on spinning physical HD,but even if Fusion image could opt for SSD virtual disk, it wouldn't really matter i guess for performance, APFS would still get more benefits over HFS+

I am still on Fusion 8.5.10 with a Sierra 10.12.6 host. But I have a High Sierra 10.3.6 VM that is running with APFS (see screenshot below).

Not exactly sure what the secret sauce is to get the APFS running inside a High Sierra VM. But I would think one requirement is that the VM is stored on SSD otherwise it won't be seen as virtual SSD by Fusion and the guest VM. (Note in the screenshot, it shows Medium Type as SSD).

This High Sierra VM started as a Sierra VM with fixed allocated virtual disk, split in multiple files and virtual SATA controller. It also has

devices.hotPlug = "FALSE"

ahci.port.hotplug.enabled = "FALSE"

in the vmx configuration file.

It got upgraded to High Sierra through Apple Software Update, if I recall correctly on version 10.3.4, but an earlier version upgrade attempt did fail. I don't recall having to explicitly choose APFS during the upgrade process.
