Should you wish to create more servers, you can clone any one of the dstesting ones available in the training wiki page.
You will however need to:
Reinitialise the MAC address of the VM
Change the static ip address in /etc/network/interfaces (And note that the interface itself (e.g. eth0) may have changed - check with 'ip addr' or 'ifconfig')
Change the hostname in /etc/hostname and /etc/hosts
