配置 yum
[root@localhost kernels]# vi /etc/yum.repos.d/1.repo
[centos]
baseurl=file:///mnt

mount -o loop /iso/CentOS-5.3-x86_64-bin-DVD.iso /mnt/

修改 xen 内核为第一启动项

[root@localhost boot]# vi /boot/grub/grub.conf

all kernel and initrd paths are relative to /boot/, eg.

root (hd0,0)

kernel /vmlinuz-version ro root=/dev/sda5

initrd /initrd-version.img

boot=/dev/sda
