Description of problem:
"SELinux is preventing chronyc from 'read, write' accesses on the chr_file /dev/tty1"
Running "chronyc sources" or "chronyc tracking" on the console of the VM does not yield results. Outputs shown as expected on running commands after ssh-ing in.

Version-Release number of selected component (if applicable):
selinux-policy-3.13.1-192.el7_5.3.noarch
chrony-3.2-2.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Build VM
2. Access the console
3. Run "chronyc" commands

Actual results:
None

Expected results:
# chronyc sources
210 Number of sources = 4

SELinux is preventing chronyc from 'read, write' accesses on the chr_file /dev/tty1.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If you want to allow all daemons the ability to read/write terminals
Then you must tell SELinux about this by enabling the 'daemons_use_tty' boolean.

Do
setsebool -P daemons_use_tty 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that chronyc should be allowed read write access on the tty1 chr_file 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:
# ausearch -c 'chronyc' --raw | audit2allow -M my-chronyc
# semodule -i my-chronyc.pp
