一.准备系统环境
1.下载kernel-xen repo镜像
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
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
mkdir-p /root/src/ cd/root/src wget ftp://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/os/SRPMS/libvirt-0.8.1-27.el6.src.rpm rpm -i libvirt-0.8.1-27.el6.src.rpm wget http://pasik.reaktio.net/xen/patches/libvirt-spec-rhel6-enable-xen.patch cd/root/rpmbuild/SPECS cp-a libvirt.spec libvirt.spec.orig patch -p0 < ~/src/libvirt-spec-rhel6-enable-xen.patch yum installebtables libcgroup lzop iscsi-initiator-utils lvm2 dnsmasq xen-devel nfs-utils libnl-devel xhtml1-dtds libudev-devel libpciaccess-devel yajl-devel libpcap-devel avahi-devel parted-devel device-mapper-devel numactl-devel netcf-devel python-devel autoconf automake libtool libxml2-devel readline-devel ncurses-devel gnutls-devel cyrus-sasl-devel libcap-ng-devel libcurl-devel rpmbuild -bb libvirt.spec /root/rpmbuild/RPMS/x86_64 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:
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
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
grub.conf generated by anaconda
# # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,0) # kernel /vmlinuz-version ro root=/dev/sda8 # initrd /initrd-[generic-]version.img #boot=/dev/sda default=0 timeout=5 splashp_w_picpath=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (3.6.7-1.el6xen.x86_64) root (hd0,0) kernel /xen-4.2.gz dom0_mem=4096M module /vmlinuz-3.6.7-1.el6xen.x86_64 ro root=UUID=1b782dd8-0693-4336-b3b3-512f8f1ed548 rd_NO_LUKS KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD crashkernel=auto.UTF-8 rd_NO_LVM rd_NO_DM rhgb quiet module /initramfs-3.6.7-1.el6xen.x86_64.img title CentOS (2.6.32-279.14.1.el6.x86_64) root (hd0,0) kernel /vmlinuz-2.6.32-279.14.1.el6.x86_64 ro root=UUID=1b782dd8-0693-4336-b3b3-512f8f1ed548 rd_NO_LUKS KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD crashkernel=auto.UTF-8 rd_NO_LVM rd_NO_DM rhgb quiet initrd /initramfs-2.6.32-279.14.1.el6.x86_64.img title CentOS (2.6.32-279.el6.x86_64) root (hd0,0) kernel /vmlinuz-2.6.32-279.el6.x86_64 ro root=UUID=1b782dd8-0693-4336-b3b3-512f8f1ed548 rd_NO_LUKS KEYBOARDTYPE=pc KEYTABLE=us rd_NO_MD crashkernel=auto.UTF-8 rd_NO_LVM rd_NO_DM rhgb quiet initrd /initramfs-2.6.32-279.el6.x86_64.img
6.重启linux
