How to Fix an Empty System Log

The System Log tab in the cloud control panel displays console output from your instance. It works by default if you installed from our KVM cloud images, but it may be empty if you installed from an ISO or your own image. You can modify your boot parameters to display console output in such cases.


  1. Access your instance via SSH or VNC console.
  2. Edit /etc/default/grub
  3. Add parameters console=tty0 console=ttyS0,115200n8 to the end of the GRUB_CMDLINE_LINUX_DEFAULT line, in between the quotation marks.
  4. Save and close the file.
  5. Ubuntu/Debian: update-grub
    CentOS/Fedora: grub2-mkconfig -o /boot/grub2/grub.cfg
  6. reboot

You should now see output on the System Log tab when your instance reboots.
