Is it possible to automatically install Windows?

Yes, via the “Windows” tab of the virtual server in the Robot you can order corresponding licenses and activate the automatic installation.

Is it possible to install Windows with my own license?

Yes, but it must be done manually. For this, the CD/DVD images can be used, see Virtual Server Guide -> Mounting CD/DVD ISO images

Why is the time on my server not correct?

All CX virtual server hosts use UTC as the system time, which is why Windows often has a problem with the system time within the vServers.

To fix this problem permanently, it is necessary to create an entry in the Windows registry, which tells Windows that the hardware clock (RTC - emulated by the host system) is not the local time zone, but UTC.

The following command must be entered in the command prompt (cmd.exe):

reg add "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation" /v RealTimeIsUniversal /d 1 /t REG_DWORD /f

It is then necessary to restart Windows.

After the restart the following command can be used to check if the setting was successfully applied:

reg query "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TimeZoneInformation" /s

If the changes were successfully applied, a line with the wording RealTimeIsUniversal and the value 0x1 should be shown.

For Windows Server 2008 and Windows Server 2008 R2 it is necessary that the following Windows Updates have been installed:

What should be kept in mind during a manual installation?

To install Windows, it is necessary that the VirtIO drivers are installed. The driver can, for example, be mounted and installed via an ISO image (virtio-win-latest[…].iso).

The folders of the necessary drivers are named as follows:

  • Balloon
  • NetKVM
  • vioscsi

Each of them will usually have a folder with the architecture (amd64). This must be selected to install the drivers.

Example instructions

To get to the selection of the available CD/DVD images, you must select your server in the Robot and switch to the "vServer" tab. You must then click on “Settings” at the bottom to open the menu.


Next, the desired image is selected and the setting saved.


Now you can start your server and perform the installation normally up to the point where the installation searches for the drive. At this point, you have to switch the image to the latest available VirtIO driver CD.


Subsequently, the below mentioned drivers need to be installed.



Each of the folders will usually have a subfolder with the architecture (amd64). This must be selected to install the drivers (see above).

After installing the driver you need to switch back to the previously used Windows Image.


Finally, you can resume the installation as normal.
