2 KVMs not allowing me to assign IP Addresses

[Danielc1234]

Hi. I have set up two KVMs using the virtio network adapters. I am able to set an ip in the second KVM server, but when I try to set an ip in the first KVM it wont let me. When I try to set an ip in centos it shows no IP address...even when I run a ifconfig command.

Am I doing something wrong or should I be setting the KVM up differently?

I have both KVM servers set up to use the virtuo adapters.

Any ideas what I am doing wrong? However I am very new so Im sure it must be something I am doing.
