yum -y install qemu-kvm libvirt virt-install bridge-utils

[root@dlp ~]#

lsmod | grep 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

# hange 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

# hange like follows

HWADDR=00:24:1D:13:7A:26
TYPE=Ethernet
DEVICE=eth0
