CentOS6下快速配置Xen 4.1.1環境

准備工作

• CentOS 6.0, Minimal安裝, SELINUX=disabled, 配置好SRPM的repo地址

操作步驟

1. 安裝基本軟件包

1. 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

2. 安裝qemu

1. wget http://mirrors.ustc.edu.cn/Fedora/linux/updates/13/x86_64/qemu-common-0.13.0-1.fc13.x86_64.rpm
2. wget http://mirrors.ustc.edu.cn/fedora/linux/updates/13/x86_64/qemu-img-0.13.0-1.fc13.x86_64.rpm
3. rpm -Uvh qemu-*.rpm

3. 通過srpm編譯安裝Xen

1. wget http://mirrors.ustc.edu.cn/fedora/linux/updates/15/SRPMS/xen-4.1.1-3.fc15.src.rpm
2. rpm -i xen-4.1.1-3.fc15.src.rpm
3. cd ~/rpmbuild/SPECS/
4. rpmbuild -bb xen.spec
5. cd ~/rpmbuild/RPMS/x86_64/
6. rpm -Uvh xen-*4.1.1-*.rpm

4. 修改bridge-utils, CentOS 6.0的默認內核被加了IGMP的patch, 其自帶的bridge-utils也打了這個patch, 在非rhel6的內核上運行會出現很多沒用的提示。

1. yumdownloader --source bridge-utils
2. rpm -i bridge-utils-1.2-9.el6.src.rpm # 版本可能不同
3. cd ~/rpmbuild/SPECS/
4. vi bridge-utils.spec
5. # 去除兩行有patch4的地方, 也即有IGMP的patch的行
6. rpmbuild -bb bridge-utils.spec
7. cd ~/rpmbuild/RPMS/x86_64/
8. rpm -Uvh --force bridge-utils-1.2-9.el6.x86_64.rpm

提供一個patch

18. autoconf

5. 安裝libvirt, CentOS6自帶的不支持xen, 需要打開xen的選項重新編譯

1. yumdownloader --source libvirt
2. rpm -i libvirt-0.8.1-27.el6_0.6.src.rpm # 版本可能不同
3. cd ~/rpmbuild/SPECS/
4. vi libvirt.spec # 按下面的patch修改
5. rpmbuild -bb libvirt.spec
6. cd ~/rpmbuild/RPMS/x86_64/
7. rpm -Uvh libvirt-*0.8.1*.rpm

Patch:

11. # If Xen isn't turned on, we shouldn't build the xen proxy either

6. 安裝python-virtinst，舊的版本不支持的參數太多了

1. # 從RedHat網站下載srpm
2. wget http://ftp.redhat.com/redhat/linux/enterprise/6Server/en/os/SRPMS/python-virtinst-0.500.5-3.el6.src.rpm
4. rpm -i python-virtinst-0.500.5-3.el6.src.rpm
6. cd ~/rpmbuild/SPECS/
7. rpmbuild -bb python-virtinst.spec
9. cd ~/rpmbuild/RPMS/noarch/
10. rpm -Uvh --force python-virtinst-*.rpm

7. 編譯安裝內核

1. # 從github下載內核
2. wget https://github.com/jsgf/linux-xen/tarball/xen-2.6.32.46 -O kernel-xen-2.6.32.46.tar.gz
3. # 下載config
4. wget http://pasik.reaktio.net/xen/kernel-config/config-2.6.32.43-pvops-dom0-xen-stable-x86_64
6. # 可以先修改config裡面的CONFIG_LOCALVERSION項, 給這個內核起個別名, 比如-dom0-xen, 以下為沒有修改的情況
7. tar xzf kernel-xen-2.6.32.46.tar.gz
8. cp config-2.6.32.43-pvops-dom0-xen-stable-x86_64 jsgf-linux-xen-1c3f03c/.config
9. cd jsgf-linux-xen-1c3f03c
10. make oldconfig
11. make -j4 bzImage
12. make -j4 modules
13. make modules_install
14. depmod -a 2.6.32.46
15. cp -a arch/x86/boot/bzImage /boot/vmlinuz-2.6.32.46
16. cp -a System.map /boot/System.map-2.6.32.46
17. cp -a .config /boot/config-2.6.32.46
18. cd /boot/
19. dracut --force initramfs-2.6.32.46.img 2.6.32.46
21. # 關閉ksm, 跟xen不兼容
22. chkconfig ksm off
23. chkconfig ksmtuned off

8. 編輯/boot/grub/menu.lst, 添加

1. title Xen 4.0 with Linux 2.6.32.46
2. root (hd0,0)
3. kernel /xen.gz dom0_mem=2048M loglvl=all guest_loglvl=all
4. module /vmlinuz-2.6.32.46 ro root=/dev/sda2 rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM KEYBO
5. ARDTYPE=pc KEYTABLE=us SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8 nomodeset
6. module /initramfs-2.6.32.46.img

9. 編輯/etc/xen/xend-config.sxp, 按自己的需求修改

1. ......
2. (xend-http-server yes)
3. (xend-unix-server yes)
4. (xend-tcp-xmlrpc-server yes)
5. ......
6. (xend-relocation-server yes)
7. ......
8. (xend-tcp-xmlrpc-server-address '0.0.0.0')
9. (xend-tcp-xmlrpc-server-port 8006)
10. ......
11. (xend-relocation-port 8002)
12. ......
13. (xend-address localhost)
14. ......
15. (xend-relocation-address '0.0.0.0')
16. ......
17. ......
18. ......

10. 配置libvirtd

1. groupadd libvirt
2. vi /etc/libvirt/libvirtd.conf
3. unix_sock_group = "libvirt"
4. unix_sock_ro_perms = "0777"
5. unix_sock_rw_perms = "0770"

11. 重啟, 啟動Xen的內核

12. 把上面做的事情, 寫成一套腳本
