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。
