Description of problem:
I created a armhf architecture virtual machine with qemu.
SELinux is preventing qemu-system-arm from 'search' accesses on the directory 920.

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

If you believe that qemu-system-arm should be allowed search access on the 920 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:
# ausearch -c 'qemu-system-arm' --raw | audit2allow -M my-qemusystemarm
# semodule -X 300 -i my-qemusystemarm.pp

    Allow svirt_tcg_t domain to read system state of virtd_t domains


This should be already fixed in SELinux policy. Could you update selinux-policy package? 

Thanks,
Lukas.
