准备工作
- CentOS 6.0, Minimal安装, SELINUX=disabled, 配置好SRPM的repo地址
操作步骤
1. 安装基本软件包
- yum -y install openssh-clients gcc g++ make automake autoconf wget glibc-devel glibc-devel.i686 libaio rpm-build yum-utils transfig libidn-devel zlib-devel texi2html SDL-devel curl-devel libX11-devel Python-devel ghostscript tetex-latex ncurses-devel gtk2-devel libaio-devel texinfo dev86 gettext gnutls-devel openssl-devel pciutils-devel libuuid-devel iasl bzip2-devel xz-devel e2fsprogs-devel PyXML kpartx bridge-utils libsysfs-devel libsysfs libnl-devel libtool nfs-utils libxml2-devel xhtml1-dtds readline-devel libudev-devel libpciaccess-devel yajl-devel libpcap-devel avahi-devel dnsmasq cyrus-sasl-devel polkit lvm2 iscsi-initiator-utils parted-devel device-mapper-devel numactl-devel libcap-ng-devel netcf-devel ebtables lzop nc cyrus-sasl-md5 python-virtinst
- wget http://mirrors.ustc.edu.cn/Fedora/linux/updates/13/x86_64/qemu-common-0.13.0-1.fc13.x86_64.rpm
- wget http://mirrors.ustc.edu.cn/fedora/linux/updates/13/x86_64/qemu-img-0.13.0-1.fc13.x86_64.rpm
- rpm -Uvh qemu-*.rpm
3. 通过srpm编译安装Xen
- wget http://mirrors.ustc.edu.cn/fedora/linux/updates/15/SRPMS/xen-4.1.1-3.fc15.src.rpm
- rpm -i xen-4.1.1-3.fc15.src.rpm
- cd ~/rpmbuild/SPECS/
- rpmbuild -bb xen.spec
- cd ~/rpmbuild/RPMS/x86_64/
- rpm -Uvh xen-*4.1.1-*.rpm
- yumdownloader –source bridge-utils
- rpm -i bridge-utils-1.2-9.el6.src.rpm # 版本可能不同
- cd ~/rpmbuild/SPECS/
- vi bridge-utils.spec
- # 去除两行有patch4的地方, 也即有IGMP的patch的行
- rpmbuild -bb bridge-utils.spec
- cd ~/rpmbuild/RPMS/x86_64/
- rpm -Uvh –force bridge-utils-1.2-9.el6.x86_64.rpm

6. 安装python-virtinst,旧的版本不支持的参数太多了
- # 从RedHat网站下载srpm
- wget http://ftp.redhat.com/redhat/linux/enterprise/6Server/en/os/SRPMS/python-virtinst-0.500.5-3.el6.src.rpm

12. 把上面做的事情, 写成一套脚本
其他配置1. libvirtd第一次启动时, 会生成一个虚拟网卡virbr0, 如果需要nat网络就留着,如果要用bridge做共享网络可以按如下方法删除
- virsh net-destroy default
- virsh net-undefine default
- service libvirtd restart
建立用于网络安装CentOS6的环境
1. 将CentOS的所有iso里面的所有文件都复制到同一个目录下
2. 在那个目录里面执行
- mkdir -p images/xen
- cp images/pxeboot/initrd.img images/xen/
- cp images/pxeboot/vmlinuz images/xen/
创建CentOS6虚拟机
1. 使用virt-install安装
- virt-install \
- -p \
- -n centos6 \
- -r 4096 \
- –vcpus=1 \
- –disk path=/home/vms/centos6/sda.img,size=2,format=’raw’,driver_name=’file’ \
- –graphics none \
- -l http://10.100.6.48/CentOS \
- -w bridge=xenbr0 \
- –os-type=linux
- # -p: paravirt模式执行
- # -n: 虚拟机名字
- # -r: 内存大小, 以MB计
- # –vcpus: 虚拟的CPU数
- # –disk: 磁盘参数, path:路径; size:大小, 以GB计; format=’raw’:raw模式; driver_name=’file’: 默认是aio:tap, 但是CentOS6的默认内核不支持, 安装时找不到硬盘
- # –graphics none: 以console模式启动
- # -l http://10.100.6.48/CentOS: 上面介绍的自己的建立CentOS的网络安装环境
- # -w bridge=xenbr0, xenbr0是与可访问安装环境的网卡绑定的网桥
2. 安装的时候建议选择VNC方式安装,console下面不能自定分区
