I want to start a script in domu, after domu receive a signal (message
anything like this) from dom0.
Consider using SSH.

Set up public key authentication, make DomU to authorize SSH login form Dom0 with Dom0's key (google "SSH public key" for your distribution).
Then run the command via ssh form Dom0, like this:

ssh root@domU-hostname "command parameters; another command if needed"
