一.准备系统环境

1.下载kernel-xen repo镜像

1
2
wget http:
//us3
.mirror.crc.
id
.au
/el6/x86_64/kernel-xen-release-6-4
.noarch.rpm
rpm -ivh kernel-xen-release-6-4.noarch.rpm

2 安装xen 内核及其相关软件

1
2
yum
install
-y xen kernel-xen xen-libs python-virtinst bridge-utils
reboot

3.重新编译libvirtrpm包，因为centos 6 中的libvirt去掉了对xen支持

rpm -i libvirt-0.8.1-27.el6.src.rpm
wget http:

rpmbuild -bb libvirt.spec

rpm -Uvh --force libvirt-0.8.1-27.el6.x86_64.rpm libvirt-client-0.8.1-27.el6.x86_64.rpm libvirt-python-0.8.1-27.el6.x86_64.rpm

4. 配置网卡为桥接模式

例如:

01

07
08
09
10
11
12
cd
/etc/sysconfig/network-scripts/
cp
-a ifcfg-eth0 ifcfg-br0
ifcfg-br0 内容为
DEVICE=
"br0"
BOOTPROTO=
"none"
HWADDR=
"6C:92:BF:00:40:CA"
NM_CONTROLLED=
"yes"
IPADDR=172.19.10.21
ONBOOT=
"yes"
TYPE=
"Bridge"
NETMASK=
"255.255.255.0"
#UUID="a833937d-9306-44d3-a011-b941d4c4dd7b"

ifcfg-eth0修改如下

1
2

4
5
6
7
DEVICE=
"eth0"
HWADDR=
"6C:92:BF:00:40:CA"
NM_CONTROLLED=
"yes"
ONBOOT=
"yes"
TYPE=
"Ethernet"
BRIDGE=br0
UUID=
"a833937d-9306-44d3-a011-b941d4c4dd7b"

修改完毕重启网卡

service network restart

5.最后修改/boot/grub/grub.conf
