[root@dlp ~]#
yum -y install qemu-kvm libvirt virt-install bridge-utils
[root@dlp ~]#
lsmod | grep kvm

kvm_intel
43336 0

kvm
306680 1 kvm_intel

[root@dlp ~]#
systemctl start libvirtd.service

[root@dlp ~]#
systemctl enable libvirtd.service

[2] Configure Bridge networking for KVM virtual machine. (Replace the ifcfg-eth0 to the name of interface on your system.)
[root@dlp ~]#
cd /etc/sysconfig/network-scripts

[root@dlp network-scripts]#
cp ifcfg-eth0 ifcfg-br0

[root@dlp network-scripts]#
vi ifcfg-br0
# change like follows

TYPE=Bridge
BOOTPROTO=none
DEVICE=br0
ONBOOT=yes
IPADDR=10.0.0.30
NETMASK=255.255.255.0
GATEWAY=10.0.0.1
DNS1=10.0.0.10
[root@dlp network-scripts]#
vi ifcfg-eth0
# change like follows

TYPE=Ethernet
DEVICE=eth0
ONBOOT=yes
BRIDGE=br0
[root@dlp network-scripts]#
reboot
[root@dlp ~]#
