Hi,
There have been reports of people who got it to work, but ...
Unfortunately Fusion 8 is not supported on High Sierra, only Fusion 10 is.
See also: Supported host operating systems
The problem with HS is getting it to work on the part of the kernel extensions that have to be approved.
It's an often reported problem with Fusion 10, on Fusion 8 that is likely worse.
If you want to try it, then at least make sure to get the very latest Fusion 8 release (currently Fusion 8.5.10, here's direct download link Download VMware Fusion 8 )
Hope this helps,
--
