Description of problem:
SELinux is preventing httpd from 'open' accesses on the file /var/www/html/phpvirtualbox/panes/chooser.html.

*****  Plugin restorecon (92.2 confidence) suggests   ************************

If you want to fix the label. 
/var/www/html/phpvirtualbox/panes/chooser.html default label should be httpd_sys_content_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /var/www/html/phpvirtualbox/panes/chooser.html

*****  Plugin catchall_boolean (7.83 confidence) suggests   ******************

If you want to allow httpd to read user content
Then you must tell SELinux about this by enabling the 'httpd_read_user_content' boolean.
You can read 'None' man page for more details.
Do
setsebool -P httpd_read_user_content 1

*****  Plugin catchall (1.41 confidence) suggests   **************************

If you believe that httpd should be allowed open access on the chooser.html 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:
# ausearch -c 'httpd' --raw | audit2allow -M my-httpd
# semodule -X 300 -i my-httpd.pp
