Hi,
For a shared VM you can set it to auto-suspend when the host shuts down.
Having said that, shared VM's do come with a number of limitations that might make them not suitable for you.
See this KB article for more details on those limitations: http://kb.vmware.com/kb/2005585
In short:
When you share a virtual machine, you lose these features:
Unity
Shared Folders
AutoProtect
drag and drop
copy and paste
Thin Print
Ability to connect/redirect USB devices from the host to the virtual machine not available with Workstation 8.x
3D Acceleration
But you're not the first bumping into this.
See this thread for more details:
VMWare Workstation 12.5 Auto Suspend of Guests when Windows Host Shuts Down
hope this helps,
