I have successfully installed xen using the HowTo at http://www.howtoforge.com/debian_etch_xen_3.1. I chose to finish the final page, which was optional, with the hope of "Creat(ing) A Virtual Local Network From The Virtual Machines". This required me to change the gateway, netmask, and IP address of the instances. My original goal was to create a virtual local network with the xen server acting as the router and name server: http://www.domain.com (domain) -> web server (port 80) (xen instance) http://trac.domain.com (domain) -> svn/trac server (port 80) (xen instance) The tutorial discusses how to use iptables to achieve port forwarding but this limits me to having one server (instance) per port. Many of my servers have there own web interface (trac, mysql, etc) which means I must somehow create a name server that provides the desired functionality (shown above). Any suggestions?
