Android-x86 을 XEN Guest(PV)로 부팅 with network

1. root.img 생성

 - [out/target/product/eeepc]# ls root
init  init.eeepc.rc  init.rc  install.img  proc  ramdisk.img  sbin  sys  system  system.img  ueventd.rc...
- $ out/host/linux-x86/bin/make_ext4fs -l 512M -a root out/target/product/eeepc/root.img out/target/product/eeepc/root

2. ramdisk의 init  스크립트 수정

- [out/target/product/eeepc/installer]# vi init

- 아래와 같이 수정

- 위의 root.img를 /dev/xvda로 연결

113 #while :; do
114     #for device in ${ROOT:-/dev/sr* /dev/xvd* /dev/[hs]d[a-z]*}; do
115     #   check_root $device && break 2
116     #   mountpoint -q /mnt && umount /mnt
117     #done
118 
119     # mount for pv guest in xen mode
120     mount -o loop /dev/xvda /mnt
121     mkdir /android/system
122     mount -o loop /mnt/system.img /android/system
123     zcat /mnt/ramdisk.img | cpio -id > /dev/null
124     mkdir cache mnt mnt/sdcard
125     mount -t tmpfs tmpfs cache
126 
127     sleep 1
128     echo -n .
129 #done

- ramdisk 생성

$ out/host/linux-x86/bin/mkbootfs out/target/product/eeepc/installer | gzip -9 > out/target/product/eeepc/initrd.img

3. DomU 생성 및 실행

- $ sudo xm create and_xen.cfg

Appendix: and_xen.cfg 예제

import os, re

builder = 'linux'

kernel  = '/home/dkyun77/dev/android-sf-x86/out/target/product/eeepc/kernel'
extra    = "loglevel=7"

ramdisk = '/home/dkyun77/dev/android-sf-x86/out/target/product/eeepc/initrd.img'

vcpus = 1
memory = 1024
shadow_memory = 16

device_model = '/usr/lib/xen/bin/qemu-dm'

disk = [ 'file:/home/dkyun77/dev/android-sf-x86/out/target/product/eeepc/root.img,xvda,w' ]
name = 'xen_eeepc'

vfb=['type=vnc,vncunused=1']

vif = ['bridge=virbr0']

stdvga=0
serial='pty'
usbdevice='tablet'

4. DomU network 활성화

- xen network 정보: http://wiki.xensource.com/xenwiki/XenNetworking

 - virt-manager를 이용해서 send-key로 'Ctrl+Alt+F1' 전송

- shell 얻음

- # netcfg -h

- # netcfg eth0 dhcp

- eth0 UP    192.168.122.146/24 xxx

- 고정 IP 사용하고 싶을 경우 mac Addr 고정

- 예: 위 xen 설정 파일의 아래와 같이 수정

- vif=[ 'mac=00:16:3e:01:01:01,bridge=virbr0' ]

- adb 연결

- 참조: http://www.android-x86.org/documents/debug-howto

- Host Ubuntu에서 실행
