How To Install Xen On Ubuntu 11.10 (Oneiric)

apt-get install xen-tools xen-utils-common xenwatch libxen-dev xen-docs-4.1 xen-hypervisor-4.1-amd64 xen-utils-4.1 xenstore-utils bridge-utils

grub:

修改set default=”2″，即启动下面的内核：

submenu “Xen 4.1-amd64” {
menuentry ‘Ubuntu GNU/Linux, with Xen 4.1-amd64 and Linux 3.0.0-12-generic’ –class ubuntu –class gnu-linux –class
gnu –class os –class xen {
        insmod part_msdos
        insmod ext2
        set root='(hd0,msdos1)’
        search –no-floppy –fs-uuid –set=root 162bc81d-3f41-45cb-adf0-d56994a2a55c
        echo    ‘Loading Xen 4.1-amd64 …’
        multiboot       /boot/xen-4.1-amd64.gz placeholder
        echo    ‘Loading Linux 3.0.0-12-generic …’
        module  /boot/vmlinuz-3.0.0-12-generic placeholder root=UUID=162bc81d-3f41-45cb-adf0-d56994a2a55c ro  quiet
splash
        echo    ‘Loading initial ramdisk …’
        module  /boot/initrd.img-3.0.0-12-generic
}

xend配置：
vim /etc/xen/xend-config.sxp添加下面一行
(network-script network-bridge)

网桥配置

cat /etc/network/interfaces   
     auto lo
     iface lo inet loopback
     auto eth0
     iface eth0 inet dhcp
/etc/init.d/networking restart
ifdown eth0
brctl delbr tmpbridge
/etc/xen/scripts/network-bridge start
确认一下是否OK了： 
brctl show
bridge name     bridge id               STP enabled     interfaces
eth0            8000.1c6f650addfe       no              peth0

ifconfig命令可以看到熟悉的eth0和peth0，但是eth0和peth0居然有相同的IP，重启后恢复正常。
