安装KVM虚拟机

1、最小化安装系统

# cat /etc/issue
CentOS release 6.6 (Final)

2、安装KVM

# grep -E -o '(vmx|svm)' --color=auto /proc/cpuinfo

# yum -y install kvm kmod-kvm qemu kvm-qemu-img

# lsmod | grep kvm
kvm_amd                40735  0
kvm                   337772  1 kvm_amd

# yum -y install bridge-utils tunctl

# cd /etc/sysconfig/network-scripts/
# cp ifcfg-eth0  ifcfg-eth0.bak
# cp ifcfg-eth0 ifcfg-br0

# cat ifcfg-br0

DEVICE=br0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
IPADDR=192.168.10.201
NETMASK=255.255.255.0
GATEWAY=192.168.10.254
TYPE=Bridge

# cat ifcfg-eth0

DEVICE=eth0
HWADDR=B8:AC:6F:12:66:3C
TYPE=Ethernet
UUID=7e7a6ba1-607e-404b-ae06-5b3f1bb78690
ONBOOT=yes
NM_CONTROLLED=no
BRIDGE=br0

3、安装libvirt虚拟化管理工具

# yum -y install virt-manager virt-viewer libvirt libvirt-python python-virtinst
# service libvirtd start
# chkconfig libvirtd on
# virsh list
Id    名称                         状态
----------------------------------------------------

4、安装vnc

# yum -y install tigervnc-server
# vncserver                       //设置vnc密码

# echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/vncservers
# /etc/init.d/vncserver restart
# chkconfig vncserver on

5、安装虚拟机

# cd /KVM/instance/fuel-6.1/

#  qemu-img create fuel-6.1.img 60G
Formatting 'fuel-6.1.img', fmt=raw size=107374182400

# qemu-img info fuel-6.1.img
image: fuel-6.1.img
file format: raw
virtual size: 60G (64424509440 bytes)
disk size: 0

# virt-install --name=fuel-6.1  --ram 4096  --vcpus=2 --disk path=/KVM/instance/fuel-6.1/fuel-6.1.img,size=100  --accelerate --cdrom /KVM/iso/fuel-6.1.iso --graphics vnc,listen=192.168.10.201,port=5920

virsh list
Id    名称                         状态
----------------------------------------------------
4     fuel-6.1                       running

# virsh vncdisplay fuel-6.1
192.168.10.201:20
