ubuntu 半虚拟化domU的安装方法

ubuntu还没有通过http://方法安装,不像redhat系的发行版.一种可行的方法是,先用iso安装成全虚拟化,然后再改成半虚拟化内核.

这里介绍另一种可能的方法.

1. install debootstrap from ubuntu site:

wget http://cn.archive.ubuntu.com/ubuntu/pool/main/d/debootstrap/debootstrap_1.0.23.tar.gz

tar zxvf debootstrap_1.0.23.tar.gz -C /usr/share

2. bootstrap a mini ubuntu

/usr/share/debootstrap lucid lucid_base

3. install a EC2 image

cd lucid_base
chroot .
apt-get install linux-image-2.6.32-305-ec2
apt-get install ssh

passwd (update password for root)


4. setup grub boot menu.lst

mkdir /boot/grub
vi /boot/grub/menu.lst

 

as:

default=0
timeout=10
title ubuntu
root (hd0,0)
kernel /vmlinuz console=hvc0 root=/dev/sda1 ro
initrd /initrd.img

5. create vdisk ,共 10G 动态增长.

 

dd if=/dev/zero of=ubuntu.lucid.10G.img bs=1 count=0 seek=10G

 

mkfs.ext3 ubuntu.lucid.10G.img

 

mount -o loop ubuntu.lucid.10G.img /mnt

 

cp lucid_base/* /mnt * -avpr

 

umount /mnt

 

6. create a vm.cfg as :

 

name = "ubuntu"
memory = "256"
disk = [ 'file:/opt/images/oraclevmm/ubuntu.lucid.10G.img,sda1 ,w', ]
vif = [ 'mac=00:16:3e:21:11:29, bridge=xenbr0', ]
vfb = ["type=vnc,vncunused=1"]
uuid = "4030b5cb-f298-90fa-2673-b809e09bb136"
bootloader="/usr/bin/pygrub"
vcpus=2
on_reboot   = 'restart'
on_crash    = 'restart'
