Issue with inactive keyboard in Virtual Box Text Console during loging

I want to ask help. Yesterday I installed ownCloud from https://www.univention.com/products/univention-app-center/app-catalog/owncloud/ in virtual box ( Download as Univention App).
All steps in this matter passed sucesfully but I encountered small isue regarding access to text console" in Virtual Box.
After writing loging name from keyboard I have no any possibility to enter any string from keyboard or clipboard. All pressing in any keys are inactive except 2 active keys Enter or tab which in result gives message Loging incorrect.
