  • Virtuozzo containers for Windows


During and after the VIrtuozzo installation, I get the following error:

Could not start the virtuozzo KSAL service.

When I start the Virtuozzo KSAL service manually, I receive the same error message as above. This also occurs when I restart the Virtuozzo service.


This behavior might be caused by Windows updates installed on the server which are not compatibe with Virtuozzo


Before installing Virtuozzo, please ensure that there are no Microsoft updates other than Service Pack 1 (or Service Pack 2 ). If any Microsoft updates are installed manually, you should uninstall them since Virtuozzo downloads the compatible updates from our Windows Server Update Service (WSUS) server.

Alternately, when Virtuozzo with all Virtuozzo updates is installed with all its product updates, you can then download and install all the Microsoft updates immediately
Please also how to keep Virtuozzo server up-to-dated.
