How to boot and install the Ubuntu server image on QEMU -nographic without the GUI?












0















At How to run Ubuntu 16.04 Desktop on QEMU? I have described in detail how to boot and install the desktop Ubuntu image on QEMU.



Now I wanted to do a similar setup for the server image to try keep things more minimal:



wget http://releases.ubuntu.com/18.04/ubuntu-18.04.1.0-live-server-amd64.iso


I have installed the server image with the GUI previously, and the setup seems to be text based, so I thought it might work.



But then, if I just add the usual:



-nographic -serial mon:stdio


as in:



qemu-system-x86_64 -cdrom ubuntu-18.04.1.0-live-server-amd64.iso 
-drive file=ubuntu-18.04.1.0-live-server-amd64.img.qcow2,format=qcow2
-enable-kvm -m 2G -smp 2 -vga virtio -nographic -serial mon:stdio


I just never get anything on the terminal serial.



I also tried to mount the image to see what was inside:



mkdir mydir
sudo mount ubuntu-18.04.1.0-live-server-amd64.iso mydir


to see what was inside, and:



cat mydir/boot/grub/grub.cfg


indicates that there is no console=ttyS0 option on the command line, which might explain why the terminal is empty.



I can't edit the ISO file however without first going into a GUI session, as it is mounted readonly.



I have already used the Cloud image previously, and it is great: Is there any prebuilt QEMU Ubuntu image(32bit) online? but I can't use it this time because I need GRUB for something (edit: nevermind, the cloud image does have GRUB, just it is hidden by default, see: How to get to the GRUB menu at boot-time using serial console? )



Related: How to get to the GRUB menu at boot-time using serial console? I managed to get GRUB to show on the terminal after changing the GRUB configuration with the GUI as shown in that thread.



Tested on an Ubuntu 16.04 host.
