First let me preface this by saying I cloned our production DNS servers via clonezilla and restored that clone to a VM on our private network.
Here's what I have and what I'm trying to accomplish.
What I have:
DNS1 is currently a bare bones physical machine. We are an ISP and it provides DNS to our customers. It currently has two interfaces, one is a public IP and the other is a private (10.x.x.x) IP.
DNS2 is a bare bones slave to DNS1, we use it as a fail safe in case DNS1 fails. It also has two interfaces, one public and the other private.
What I want to accomplish:
Virtualize both servers. I have ESXi 5.1 running on a server in my office, on a 192 network. I want to clone them both to my office server, get it operable, then do the same to the other two physical machines. If one box fails, simply light up a VM on the other physical EXSi box. Once I have them operable in my office, I will install the server in our data center and work on getting the other two configured the same.
I've restored the clone of DNS2 to my office ESXi box, but believe I have some networking issues. I tried reconfiguring the network parameters in /etc/sysconfig/network-scripts/eth0 & eth1 to my local network, but get the following when I try restarting networking: "Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization."
Anybody have any advice?
PS-They are running CentOS 6.3
