Hi folks, I've been reading through the list a bit, and also looked at the KVM How-To on the wiki (http://wiki.centos.org/HowTos/KVM ) but I still have a question. I haven't yet begun to set up KVM, so I haven't made any mistakes yet. :-)
My company recently rented a server on which CentOS 5.0 is installed, and my goal is to set up a virtualized instance of CentOS for a new employee to tinker and learn on before I let him have hands on the real server. What I want to do is set up CentOS in KVM, and assign it one of the unused IP addresses on the server so that he and I can access it without having to first connect to the real server. The wiki didn't really give me a good idea of how to accomplish this, and I haven't done a bridge before, so I wanted to check with the list to see if I could get some advice on how to accomplish this.
For demonstration purposes, lets say that the external IP address of the real server is 10.0.0.1, and I want the virtualized install to be found at 10.0.0.2. Can someone show me how to modify the kvm rules found on the wiki (and pasted below) to accomplish this?
Thanks! Raymond
