Problem Description
======================
Assume selinux is set to Permissive to avoid JVM confgiure error.
Try to setup dir /exports/iso as the default ISO domain for oVirt, it is passed if it is the first time to use the dir as iso domain.

Clean up the oVirt engine, and run engine-setup again with the same dir /exports/iso. Then it comes to the error:

Expected Behavior
======================
Succeed to setup oVirt engine.

Observed Behavior
======================
Can't configure ISO domain for oVirt engine if the dir is configured once.

Logs
======================
Attached.

Misc Info 
======================
In wrlinux, semanage always returns 1:
root@localhost:~# setenforce 0
root@localhost:~# getenforce 
Permissive
root@localhost:~# /usr/sbin/semanage fcontext -a -t public_content_rw_t /exports/iso\(/.*\)?
/usr/sbin/semanage: File context for /exports/iso(/.*)? already defined
root@localhost:~# echo $?
1
root@localhost:~# setenforce 1
root@localhost:~# getenforce 
Enforcing
root@localhost:~# /usr/sbin/semanage fcontext -a -t public_content_rw_t /exports/iso\(/.*\)?
root@localhost:~# echo $?
1

But in Fedora, semanage always returns 0:
[root@ovirt-engine ~]# setenforce 0
[root@ovirt-engine ~]# getenforce 
Permissive
[root@ovirt-engine ~]# /usr/sbin/semanage fcontext -a -t public_content_rw_t /exports/iso\(/.*\)?
[root@ovirt-engine ~]# echo $?
0

[root@ovirt-engine ~]# setenforce 1
[root@ovirt-engine ~]# getenforce 
Enforcing
[root@ovirt-engine ~]# /usr/sbin/semanage fcontext -a -t public_content_rw_t /exports/iso\(/.*\)?
[root@ovirt-engine ~]# echo $?
0

Steps to Reproduce

step 1; /buildarea1/product/wrlinux-ovp/wrlinux/configure --enable-board=intel-xeon-core --enable-rootfs=ovp-ovirt-engine --enable-addons=wr-ovp --with-package=wrs-kvm-helper --with-template=feature/openvswitch,feature/vxlan --enable-parallel-pkgbuilds=5 --enable-jobs=5 --with-sstate-dir=/buildarea1/build/PUBLIC_SSTATES/intel-xeon-core
step 2; make fs
step 3; Boot intel-xeon-core target
step 4; On target, run command:
    # setenfore 0
    # engine-setup
    Use /exports/iso as the default ISO domain
    # engine-cleanup
    # rm -rf /exports/iso
    Remove /exports/iso from /etc/exports

    Then setup the ovirt engine again:
    engine-setup
    Use the same dir: /exports/iso
