(you can refer to our installation log in attache file)

$ sync ; sudo reboot

2. Check Xen

  • Check our Xen system 
    $ uname -a

  • Configure our Xen environment 
    $ vim /etc/xen/xend-config.sxp
71:    network-script network-bridge
87: #network-script netwok-dummy

$ xend restart
$ xm list



3. Xen Operation

3.1 Install Guest OS (DomU)

  • To create simple Guest OS, try xen-create-image which is included in ​xen-tools 
    $ man xen-create-image
  • Install Guest OS 
    $ sudo mkdir /home/xen_img
$ sudo dd if=/dev/zero of=/home/xen_img/etch.img bs=1G count=5
$ sudo dd if=/dev/zero of=/home/xen_img/etch.swap bs=514MB count=1
$ sudo /home/xen_img/mkfs.ext3 etch.img
$ sudo /home/xen_img/mkswap etch.swap
$ sudo mount -o loop etch.img /mnt
$ sudo debootstrap --arch i386 etch /mnt/ http://free.nchc.org.tw/debian
  • Config Guest OS 
    $ sudo vim /etc/fstab
/etc/fstab
/dev/hda1    /          ext3      defaults 0 1
/dev/hda2   swap    swap      defaults 0 0
proc             /proc   proc      defaults 0 0

$ sudo vim /etc/hostname
etch

$ sudo vim /etc/hosts
$ sudo vim /etc/network/interfaces
$ sudo cp /etc/apt/sources.list /mnt/etc/apt/
$ sudo cp -r /lib/modules/2.6.18-6-xen-686/ /mnt/lib/modules/

$ sudo chroot /mnt
$ passwd root
$ adduser rock
$ sudo umount /mnt
  • Edit Guest OS configuration 
    $ sudo vim /home/xen_img/etch.cfg
# Kernel image
kernel = "/boot/vmlinuz-2.6.18-6-xen-686"
ramdisk = "/boot/inird.img-2.6.18-6-xen-686"
# Domain name
name = "etch"
# 0achine information
vcpus = 4
memory = 256
disk = ['file:/home/xen_img/etch.img,hda1,w','file:/home/xen_img/etch.swap,hda2,w']
vif = ['mac=00:00:00:00:00:01,bridge=xenbr1']
  • Guest OS problem 
    $ mount /home/xen_img/etch.img /mnt
$ chroot /mnt
