Description of problem:

When qemu crashes, gdb is not allowed ptrace access on processes labelled svirt_t. I would expect, that if gdb is run automatically, SELinux policy should not prevent its usage.

Basically, it is a conflict of two tools in default configuration.

################################################################################

SELinux is preventing /usr/bin/gdb from using the ptrace access 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.
Do
allow this access for now by executing:
# grep gdb /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
