Hi,
I have run the below command to install Kali Linux using linux-2020.4-installer-amd64.iso from https://www.kali.org/downloads/

I am not able to get the root login prompt when I run the below command to set IP and hostname for the guest OS. Am I missing any parameters from

Just a hunch, maybe --extra-args work only for installation and are not persistent? I guess installer doesn't persist kernel cmd line passed in
Exactly, --extra-args is just for convenience of not having to edit the kernel cmdline manually when the serial console/GUI window opens with grub.

Hi Erik,
Thanks for your reply. I am not sure if I completely understand it. Is there an issue in the below command? Do I need to remove --extra-args "console=ttyS0" in the below command to have ssh console access to the KVM Guest VM? Please suggest.
#virt-install --name kalilinux --memory 4096 --vcpus=2 --location=/linuxkvmaddgbdisk/kali-linux-2020.4-installer-amd64.iso,kernel=install.amd/gtk/vmlinuz,initrd=install.amd/gtk/initrd.gz --network=bridge:br0 --os-type=linux --os-variant=debian9 --graphics=none --extra-args "console=ttyS0" -v --disk path=/linuxkvmaddgbdisk/kalilinux.img,size=50
I look forward to hearing from you. Thanks in Advance.
For accessing your guest via SSH you do not need a serial console. SSH works over network, not serial consoles.
And those --extra-args: just take virtualization out of the picture for a second. You bought yourself a new desktop and want to install a distro onto it. You plug an USB stick in and as the installer boots you change the kernel cmd line. Then you proceed with installing the distro. I don't think that the installer will copy those extra kernel args you added into the freshly installed grub, why would it?
Therefore, when you want to have some extra args after the installation, you have to edit the guest. Since at this point you are not booting kernel directly, libvirt/qemu can't help you and you need to hand edit grub config in the guest. And in this specific case, there is an alternative approach - editing /etc/inittab so that the init enables serial console.
Unless that specific Kali version is powered by systemd (which it most likely is) in which case you're going to see a note in /etc/inittab that it's deprecated and changes will be ignored. IMO the safest bet here is to edit the grub config as Michal suggested as the first option. Regards, Erik
