[Libguestfs] building a supermin appliance with febootstrap...

Rich, So, I tried to build the simple supermin app. from your blog. I can confirm that I did get to the shell when I invoked qemu-kvm. I used the standard qemu-kvm cmdline (but appended a serial console). This boots fine. ######################################################## [root@moon appliance-test]# qemu-kvm -kernel kernel -append "console=tty0 console=ttyS0,115200" -initrd initrd -hda root -nographic . . . insmod: error inserting 'ideapad-laptop.ko': -1 Unknown symbol in module insmod: wait: File exists febootstrap: insmod sym53c8xx.ko febootstrap: picked /sys/block/sda/dev as root device febootstrap: creating /dev/root as block special 8:0 febootstrap: mounting new root on /root febootstrap: chroot /proc/uptime: No such file or directory Welcome to my world bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell bash-4.2# [ 1.103034] input: ImExPS/2 Generic Explorer Mouse as /devices/platform/i8042/serio1/input/input2 [ 1.334183] Refined TSC clocksource calibration: 1995.006 MHz. bash-4.2# ######################################################## But when I try to 'exit', I notice a kernel panic. And it just seems to hung there, no more budging. I had to do 'ctl a + x' to get out of the serial console. Is this expected? ######################################################## bash-4.2# exit exit [ 153.520309] Kernel panic - not syncing: Attempted to kill init!
