Disable the annoying suspend feature for a virtual machine in VMware Fusion

A VM running in VMware Fusion goes to suspend, if it idles some time, this often results in a broken state on disk (you loose the current state of the VM and you have to restart it from the initial state).
To prevent that VMware Fusion suspends the VM, you have to edit the regarding vmx file of that machine.
First close VMWare Fusion.

Then:

cd your-machine.vmwarevm && nano your-machine.vmx

Add

suspend.disabled = "TRUE"

to disable the suspend feature of that VM. To re-enable the feature afterwards, just remove this line.
