Installing OpenVZ with ISPConfig an Ubuntu 20.04

I have recently installed ISPConfig using these instructions: https://www.howtoforge.com/tutorial/ispconfig-multiserver-setup-debian-ubuntu/
Upon logging in I see that the VServer is not configured. How would I install it and configure it to work with ISPConfig post installation?

 

You cannot as OpenVZ is no longer supported.

 

I see. Is there another method of adding the ability to create virtual servers?

 

Not in ISPConfig. You can try proxmox, kvm or similar softwares.
