socat for serial connection between 2 VM's

Hello

I have a setup where we need to connect serial ports of 2 VM's with each other.
I have found a solution to add serial sockets to the 2 VM's and connect them via socat:


This has to be active all the time.

Does anyone know if it is possible to run this in the background when the two VM's have been booted?
Via a hookscript?

Thanks!
