How to convert a physical server to a VM running through Virt-Manager VM infrastructure

Dear experts;

I used vmware's converter a lot for clone physical machines to vm but now I jumped to a new company, they don't use vmware's product, they use open source "Virtual machine manger" which is running on CentOs. Can I have a similar tool to clone physcial box and put it on this infrastructure.

thanks.

The tool we are using now is from: http://virt-manager.org/

The manual is here: http://www.centos.org/docs/5/html/Virtualization-en-US/index.html 

the picture shows the interface.
