As Hilko says, this is normal behaviour when the init process dies:

http://lxr.linux.no/#linux+v3.0.2/kernel/exit.c#L728

In libguestfs, our "init process" is the guestfsd daemon.  We
configure the kernel to reboot instead of panicking by adding the
kernel command line option "panic=1".

If you use a real init or systemd then this won't be an issue because
init will issue a reboot system call instead of exiting.
