[gem5-users] Re: "qemu: Error launching VM: Qenu failed to start" when using Packer to create a disk image and running Gem5 FS Sim

Respectful Hoa: Great insight info and tips! I am following up with correction. 1. Nested virtualization is not enabled in default, so I need to restart from scratch including VM Virtual Box, I believe that is the root cause. 2. I am trying the other option of no accelerator. Again, much

Hi, I wanted to add that, if nested virtualization is not an option, you can remove the "accelerator": "kvm" line in the json file. Without kvm, the process might take a few hours.

It seems that qemu is not installed in your system. Please try to install it by `sudo apt install qemu-kvm qemu` Kind regards, Chrysanthos Pepi From: minhui via gem5-users Sent: Saturday, November 12, 2022 18:44 To: gem5-users@gem5.org Cc:

Hi minhui, Try to `$ export PACKER_LOG=1`, and then run it again to see more details. I had a similar issue recently and was about qemu permissions. I was able to fix it by `sudo`, or by changing permission to /dev/kvm ` sudo chown /dev/kvm` Kind regards, Chrysanthos Pepi From: minhui via
