Is it possible to run a shell script on the host when a VM is started?

Folks:

My VM is configured to use some network services on the host mac via the virtual network, but as the virtual network is not up when the host's services are started they aren't listening on the virtual interface and the VM can't connect to them. After starting the VM I have to restart those services so that they are listening on the virtual network.

I'd like to automate this process if possible. Is there any way to the Parallels to run a shell script on the host after a VM is started?

Thanks!
