engine-setup show the new error with selinux. when it run semanage command. i use /virt/iso as ISO Domain. I think it generate a bad pattern for add new context.below is some part of log:

Hey Mohsen;

Did you check /etc/sysconfig/selinux to ensure that "SELINUX=enforcing"?

If you set it with setenforce, it would have reverted to whatever is in that 
file on any reboots.

At least that was my problem when I got that error.
