1.安裝XEN?

Java代碼??

yum?-y?install?xen*??

yum?-y?install?kernel-xen*??

2.驗證安裝?

Java代碼??

#ls?-lh?/boot??

-rw-r--r-- 1 root root 2.1M 06-01 02:33 vmlinuz-2.6.18-238.12.1.el5xen?
-rw-r--r-- 1 root root 412K 06-01 01:15 xen.gz-2.6.18-238.12.1.el5?
-rwxr-xr-x 1 root root 956K 06-01 03:27 xen-syms-2.6.18-238.12.1.el5?

3.檢查grub配置?

Java代碼??

#cat?/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 do not have a /boot partition.? This means that?
#????????? all kernel and initrd paths are relative to /, eg.?
#????????? root (hd0,0)?
#????????? kernel /boot/vmlinuz-version ro root=/dev/sda1?
#????????? initrd /boot/initrd-version.img?
#boot=/dev/sda?
default=1?
timeout=5?
splashimage=(hd0,0)/boot/grub/splash.xpm.gz?
hiddenmenu?
title CentOS (2.6.18-238.12.1.el5xen)?
??????? root (hd0,0)?
??????? kernel /boot/xen.gz-2.6.18-238.12.1.el5?
??????? module /boot/vmlinuz-2.6.18-238.12.1.el5xen ro root=LABEL=/?
??????? module /boot/initrd-2.6.18-238.12.1.el5xen.img?
title CentOS (2.6.18-164.el5)?
??????? root (hd0,0)?
??????? kernel /boot/vmlinuz-2.6.18-164.el5 ro root=LABEL=/?
??????? initrd /boot/initrd-2.6.18-164.el5.img?
修改其中的default=1為default=0，啟用xen內核?

4、檢查XEN是否正常?
重新啟動計算機?
1）執行?

Java代碼??

#?xm?list??

Name????????????????????????????????????? ID Mem(MiB) VCPUs State?? Time(s)?
Domain-0?????????????????????????????????? 0???? 7531???? 4 r-----???? 17.5?
出現上述結果表示xen啟動正常?

2）檢查log?

Java代碼??

#ls?-lh?/var/log/xen??

drwx------ 2 root root 4.0K 05-10 05:30 console?
-rw-r--r-- 1 root root?? 36 06-25 01:20 xend-debug.log?
-rw-r--r-- 1 root root 2.0K 06-25 01:20 xend.log?
# cat /var/log/xen/xend-debug.log?
Nothing to flush.?
Nothing to flush.?
表示一切正常，我們的CentOS5中的XEN服務已經成功啟動。?
至此，我們的CentOS5的宿主機已經安裝就緒。
