For example with this command : $ /opt/qemu-3.0.0/bin/qemu-system-x86_64 --curses -enable-kvm -drive file=3Dfile.dd,index=3D0,media=3Ddisk -drive file=3Dcentos- x86_64.iso,index=3D1,media=3Dcdrom [ 3.047614] Failed to execute /init [ 3.048315] Kernel panic - not syncing: No init found. Try passing in= it=3D option to kernel. See Linux Documentation/init.txt for guidance. [ 3.049258] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.10.0-693.21.1.= el7.x86 Increasing the size from the default 128MiB to 512MiB let the VM works wi= thout problem. So, ok, it's not a qemu problem, it's more a "User problem" and interface= problem for me. But it push me in the end to launch VirtualBox instead of qemu, because t= he default parameter does not work anymore... And I had no time to investig= ate why it does not work because the message is not visible. Debian iso with the same command line for example show a message to tell = me that there is not enough memory, so it help me to track the real issue b= ehind. But... In the end, I think today, the default memory parameter on x86_64 = is too small and it can lead some people like me to switch to VirtualBox. VirtualBox, in the wizard is set by default to 4MiB Ram size, which tell = you... Ok I need to put more. And, you know that 4MiB is not enough in the = end.
