[AMD Official Use Only - General] At this point I would check if the other KVM scripts are working for you (there are some simple tests somewhere like boot Ubuntu and exit). KVM works on some CPUs better than others, I believe, or at least this was true in the past. I have a few other ideas to try, but I would like to see if any other scripts are working first and understand your setup to see if other folks might run into the same issue in the future.

Use proper caution when opening attachments, clicking links, or responding. Thank you for your response. I double checked my image and kernel, I don't think KVM is hanging but the progress seems to be a character printed on the term every once in a while. I assume this is even before it could finish booting. Not sure if fastfoward could help here My term output: ==== m5 terminal: Terminal 0 ==== [ 0.000000] Linux version Thanks, Rajesh On Tue, Dec 6, 2022 at 4:20 PM Poremba, Matthew <matthew.pore...@amd.com<mailto:matthew.pore...@amd.com>> wrote: [AMD Official Use Only - General] Hi Rajesh, I looks like no progress has been made since a very early tick number (the timestamp print by Linux is equal to the current simulation tick / 1 trillion). For reference it should take no more than 1-3 wall clock minutes to full boot Linux and begin running the application with the KVM CPU. I have seen fairly rarely where the KVM simply hangs and makes no progress but simply running again fixed this. Your command looks correct though. Maybe someone who knows more about debugging KVM can comment how to see what the KVM CPU is doing. -Matt From: Rajesh Shashi Kumar via gem5-users <gem5-users@gem5.org<mailto:gem5-users@gem5.org>> Sent: Tuesday, December 6, 2022 2:06 PM To: gem5 users mailing list <gem5-users@gem5.org<mailto:gem5-users@gem5.org>> Cc: Rajesh Shashi Kumar <reachrajesh...@gmail.com<mailto:reachrajesh...@gmail.com>> Subject: [gem5-users] GPU-FS simulation progress Caution: This message originated from an External Source.
