I'm attempting to set up my first guest set up under KVM and am having trouble getting the network working.
The host machine "vm_host_box" has a static IP of 126.96.36.199.
The guest I am setting up needs to have a static IP of 188.8.131.52.
I currently have zero connectivity to anything (including gateway) from the guest VM. Note that the guest VM is a minimal install and I'm not able to install any additional packages due to not having network for yum.
Here's what I can see from the host:
[root@vm_host_box ~]# cat /etc/sysconfig/network-scripts/ifcfg-em1 TYPE=Ethernet BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=no NAME=em1 UUID=some-string-here DEVICE=em1 ONBOOT=yes DNS1=184.108.40.206 DOMAIN=vmhostbox.my.domain IPV6INIT=no IPADDR=220.127.116.11 PREFIX=23 GATEWAY=18.104.22.168
list of other ifcfg-* files:
[root@vm_host_box network-scripts]# ls ifcfg-* ifcfg-em1 ifcfg-em2 ifcfg-em3 ifcfg-em4 ifcfg-lo
ip addr details:

brctl shows a bridge, but there is an interface listed and I'm not sure how it was added.
[root@vm_host_box ~]# brctl show bridge name bridge id STP enabled interfaces virbr0 8000.525400113f7e yes virbr0-nic
virsh details for the default network. I'm unclear about the range of IPs. Will virsh be creating a new subnet, or am I telling it what IP's to look out for?
[root@vm_host_box ~]# virsh net-list --all Name State Autostart Persistent ---------------------------------------------------------- default active yes yes [root@vm_host_box ~]# virsh net-edit default <network> <name>default</name> <uuid>0b06b7c0-708f-4925-a8f6-84587bf96575</uuid> <forward mode='nat'/> <bridge name='virbr0' stp='on' delay='0'/> <mac address='52:54:00:11:3f:7e'/> <ip address='192.168.122.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.122.2' end='192.168.122.254'/> </dhcp> </ip> </network>
Here's what I am showing under KVM's Connection Details screens:
Here is the config after starting the Guest (labeled "rhel7")
Any pointers would be greatly appreciated.
