Description of problem:
SELinux is preventing /usr/bin/xauth from 'write' accesses on the directory /root.

*****  Plugin restorecon (99.5 confidence) suggests  *************************

If you want to fix the label. 
/root default label should be admin_home_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /root

*****  Plugin catchall (1.49 confidence) suggests  ***************************

If you believe that xauth should be allowed write access on the root directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep xauth /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
