With this patch, if the boot parameters are specified, the following virt-install command is executed for guest import or installation

Example Config file

kernel_args = "root=/dev/sda2 console=hvc0,ttyS0,115200"
kernel = "/boot/vmlinuz-6.11.0-rc3-gd7a5aa4b3c00"
initrd = "/boot/initramfs-6.11.0-rc3-gd7a5aa4b3c00.img"
