If you want it to reliably persist across reboots then the semanage tool
is very handy:

 # ls -lZ /dev/xvc0 
 crw--w----  root tty root:object_r:device_t           /dev/xvc0
 # semanage fcontext -a -t tty_device_t -f -c /dev/xvc0 
 # restorecon /dev/xvc0
 # ls -lZ /dev/xvc0 
 crw--w----  root tty system_u:object_r:tty_device_t   /dev/xvc0


I opened a bug about the SELinux policy problem - bz 213277
