liveinst failed on my own live iso

[jie sun]

I try to run liveinst after I run livecd-creator to create a live cd iso on fc7.
And I got the following errror:

[root@localhost tmp]# liveinst
FATAL: Module md not found.
/usr/sbin/setenforce: SELinux is disabled

    anaconda.intf.run(anaconda)
IOError: [Errno 22] Invalid argument

Any idea?
