Description Timur Kristóf 2014-09-17 11:27:02 UTC
Description of problem:
I tried to add a virtual machine in the Gnome Boxes application.
SELinux is preventing /usr/bin/qemu-system-x86_64 from 'open' accesses on the file .

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

If you want to allow virt to use fusefs
Then you must tell SELinux about this by enabling the 'virt_use_fusefs' boolean.
You can read 'None' man page for more details.
Do
setsebool -P virt_use_fusefs 1

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

If you believe that qemu-system-x86_64 should be allowed open access on the  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:
# grep qemu-system-x86 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
