Błąd podczas instalacji Windows 7 na Virtualboxie.
Kod błędu: 0xc0000225
Rozwiązanie:
Zmiana ustawień maszyny w Virtualboxie:
chipset from PIIX3 to ICH9
enabled IO APIC
Najpierw tworzymy nowy katalog na pliki strony
sudo mkdir -p /var/www/example.com/public_html
I nadajemy odpowiednie uprawnienia
sudo chown -R $USER:$USER /var/www/example.com/public_html
sudo chmod -R 755 /var/www
Dodajemy nowy plik konfiguracyjny w katalogu /etc/apache2/sites-available
sudo nano /etc/apache2/sites-available/example.com.conf
<VirtualHost *:80>
ServerAdmin admin@example.com
ServerName example.com
ServerAlias www.example.com
DocumentRoot /var/www/example.com/public_html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Aktywujemy nową stronę i restartujemy apache
sudo a2ensite example.com.conf sudo service apache2 restart

-a option is a combination flag. It stands for "archive" and syncs recursively and preserves symbolic links, special and device files, modification times, group, owner, and permissions.
-z If you are transferring files that have not already been compressed, like text files, you can reduce the network transfer by adding compression with the -z option:
-P flag is very helpful. It combines the flags --progress and --partial. The first of these gives you a progress bar for the transfers and the second allows you to resume interrupted transfers
