If vhv_enabled = true, results in the following in the .vmx:

...
uuid.action = "create"
vhv.enable = "TRUE"
virtualhw.productcompatibility = "hosted"
...

If vhv_enabled = false or not provided, results in the following in the .vmx:

...
uuid.action = "create"
vhv.enable = "FALSE"
virtualhw.productcompatibility = "hosted"
...
