Hello everyone, I am new to gem5 and I have been trying to use gem5 for X86 dual-core full system simulation, following the steps in this tutorial: https://www.gem5.org/documentation/gem5-stdlib/x86-full-system-tutorial. However, I encountered some issues during the process. I am unable to use m5term as described in the tutorial. I executed ./build/X86/gem5.opt configs/humiao/double.py as instructed but when I open a new terminal and run ./m5term localhost 3456, nothing happens. I would greatly appreciate it if someone could help me with this. Thank you very much. I use docker images to build and run my gem5(version 20.04). My ubuntu is 22.04. Here is the logs.

Hi, The problem seems to be that the gem5 simulation and the m5term call are run on different virtual machines. If you're using docker then please make sure that you're calling m5term on the same docker container as the one running gem5 simulation. If that doesn't work then you can check the guest output from m5out/board.platform.termnial file (or a file with the name similar to that) .
