Thank you for your time. I tried using the provided example for booting Ubuntu from a disk-image.
*./build/X86/gem5.opt configs/example/gem5_library/x86-ubuntu-run.py* With this, I see that the boot did complete with this example and *kvm-ok* returns as expected on my machine. Also, I should mention that I'm using the pre-compiled image/kernel for GPU-FS to rule out any uncertainty there. Term output: Welcome to Ubuntu 18.04.2 LTS! systemd[1]: Set hostname to <gem5-host>. systemd[1]: File /lib/systemd/system/systemd-journald.service:36 configures an IP firewall (IPAddressDeny=any), but the local system does not support BPF/cgroup based firewalling. systemd[1]: Proceeding WITHOUT firewalling in effect!
