Yesterday i had the same prob with my owncloud Xampp i thing i can help :)
So i have installed the newest virtualbox and the VM with same Version as you have only for you to check where the failure is.
http://127.0.0.1/core/doc/admin/installation/installation_source.html
Follow this is it the Manuell way to install ownclound. USE IT AS A CHECKLIST.
1. Start your VM
2. Login: root
3. Password: linux
Quote:if u have change your password with the "passwd root [enter]" in a session before than take the new password for login
4. passwd root [enter]
Quote:change your password to protect this VM and Host its running on it
5. Get the ip of the VM use ifconfig
Quote:if u wanna change your Mysqlpassword before u start a new Owncloud installation just use phpmyadmin. For example Open browser, point at ipaddress/phpmyadmin or 192.168.1.1/phpmyadmin or 127.0.0.1/phpmyadmin or localhost/phpmyadmin or http://yourdomain.com/phpmyadmin . Use for log on User: root and for Password: owncloud42 .
If u are log on click the Users button @ the Top middle frame . Users gonna open for you now. Now thoose the lower root user it has as host the localhost and click on change User rights. Pop are open search for the password change fields and change the password and than save it. If Myphpadmin are not installed u can get it http://phpmyadmin.net their is a good documentation and a wiki also if u have questions for phpmyadmin.
6. Open browser, point at ipaddress/owncloud for example 192.168.1.1/owncloud or 127.0.0.1/owncloud or localhost/owncloud or http://yourdomain.com/owncloud
7. Create a login and username for the admin/root Account of your Owncloud
Quote: take not the same login/password combination is use for VM
8. Enter MySQL options
9. Mysqlusername: root
10. Mysqlpassword: owncloud42
11. Mysqldatabasename: owncloud
Quote:you can take everything you but dont use oc_4
12. and click ok/start
13. try to get in
14. if all work to this moment and u are in the account next step 15 if not fall back to 1
15. check the cofig files

-Image Viewer
-Media
-Pictures
-Updater
-User Account Migration
-Webfinger
-ownCloud Instance Migration
-ownCloud dependencies info
-App Framework 3rd Party
-Files move 3rd Party
your backend app are in standard edition
20. to test the external storage app just log in ass root/admin and do to adminsnistrator page
and add a local storerage for example : click on local give the folder anddtional name and give it a path like C:\Users\mywindowsusersname\Documents or /home/mylinuxloginname/
and give it free for an ownclous user or a group red light edit something its was wrong green go to yourownclouds start page the must be a new folder with name u give or it name is local
for your backend no idea how to but with this step by step checking u r able to aktivate it in your app center .
good luck and have big pod of coffee :)
