How much memory and how many processors does the VM running UERANSIM have?

Hello! I am using UERANSIM with Oracle VM.
I would like to know the minimum amount of memory and number of processors required.

I use 4G RAM and 2 cores, and it works fine.

By the way, we are free5GC not UERANSIM. Detailed requirements you can refer to UERANSIM Github.
