OpenVZ in ispconfig v2

I'm using ispconfig v2 on Debian lenny X86_64
If I follow this guide http://www.howtoforge.com/installing-and-using-openvz-on-debian-lenny-amd64

Is it will destroyed my ispconfig?

 

You want to install OpenVZ on a host where you have installed ISPConfig? I don't see any problems.

 

because of it need to install new kernel linux-image-openvz-amd64.
I never install openvz before.
Thank you for your confirm I'll try very soon.
