Description of problem:
SELinux is preventing /usr/bin/gdb from using the 'ptrace' accesses on a process.

*****  Plugin catchall (100. confidence) suggests   **************************

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