系统版本及内核：CentOS release 6.7 (Final) 2.6.32-573.el6.x86_64
软件版本：xen 4.2.5

1、查看服务器是否支持半虚拟化，查看flags 一栏中是否有 pae

1 2	[iyunv@localhost /]# cat proc/cpuinfo flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts mmx fxsr sse sse2 ss syscall nx rdtscp lm constant_tsc up arch_perfmon pebs bts xtopology tsc_reliable

2、安装安装bridge-utils

1	yum install -y bridge-utils

3、在 http://au1.mirror.crc.id.au/repo/el6/x86_64/ 下载相应的rpm包

1 2 3 4 5 6

kernel-xen-3.18.24-1.el6xen.x86_64.rpm      xen-debuginfo-4.2.5-16.el6.x86_64.rpm xen-libs-4.2.5-16.el6.x86_64.rpm kernel-xen-devel-3.18.24-1.el6xen.x86_64.rpm   xen-devel-4.2.5-16.el6.x86_64.rpm   xen-licenses-4.2.5-16.el6.x86_64.rpm kernel-xen-firmware-3.18.24-1.el6xen.x86_64.rpm  xen-doc-4.2.5-16.el6.x86_64.rpm    xen-ocaml-4.2.5-16.el6.x86_64.rpm xen-4.2.5-16.el6.x86_64.rpm           xen-hypervisor-4.2.5-16.el6.x86_64.rpm xen-runtime-4.2.5-16.el6.x86_64.rpm

4、安装这些rpm包

1 2 3 4

yum install -y xen-* yum install kernel-xen-firmware-3.18.24-1.el6xen.x86_64.rpm yum install kernel-xen-devel-3.18.24-1.el6xen.x86_64.rpm yum install kernel-xen-3.18.24-1.el6xen.x86_64.rpm

5、修改内核参数

[iyunv@localhost ~]# cat /etc/grub.conf
