Description of problem:
SELinux is preventing worker from 'read' accesses on the файл /home/evgeniy/.cache/gnome-boxes/winxp-unattended.img.

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

If вы считаете, что worker следует разрешить доступ read к winxp-unattended.img file по умолчанию.
Then рекомендуется создать отчет об ошибке.
Чтобы разрешить доступ, можно создать локальный модуль политики.
Do
allow this access for now by executing:
# ausearch -c 'worker' --raw | audit2allow -M my-worker
# semodule -X 300 -i my-worker.pp
