OpenSuse 11.2 dom0 - PV domU VM creation from CentOS5.4 DVD & http setup

오랜만에 Posting...^_^;;;

Sorry for all these English notations.

1. Get Cent5.4 DVD iso file be prepared in local disk(download it!)

 # wget http://blahblah/*.iso  => save it to /home/vmimg_src/cent54dvd.iso

2. Prepare sparse file for disk image & get filesystem ready(24GB virtual disk image)

 # dd if=/dev/zero of=/home/vmimg/centvdisk.img bs=6k seek=4096k count=1

 # mkfs.ext3 /home/vmimg/centvdisk,img

3. Mount iso image to loop device

 # losetup -f => Check free loop device number, consider its loop7

 # losetup -f /home/vmimg_src/cent54dvd.iso => assign iso to /dev/loop7

 # mkdir -p /mnt/iso/cent54dvd

 # mount -t iso9660 /dev/loop7 /mnt/iso/cent54dvd

4. Make httpd be prepared and copy all the installation files

 # mkdir /home/www/cent54

 # vi /etc/apache2/default-server.conf, modify

<Directory “/home/www/cent54”>

Options Indexes FollowSymLinks

AllowOverride None

Order allow,deny

Allow from all

</Directory>

 # /etc/init.d/apache2 restart

 # cp -a /mnt/iso/cent54dvd /home/www/cent54

5. Make VM boot loader be prepared

 # cd /home/vmimg

 # mkdir cent54boot; cd cent54boot

 # cp /home/www/cent54/images/xen/vmlinuz ./vmlinuz-install-xen

 # cp /home/www/cent54/images/xen/initrd.img ./initrd-install-xen

6. edit CentOS PV domu configuration

 # cd ~/xen_config

 # vi cent54domu.cfg

-----------------------------------------------------------------------------

name='centOSdomU'

# After installation boot, disable these 2 lines

kernel='/home/vmimg/cent54boot/vmlinuz-install-xen'

ramdisk='/home/vmimg/cent54boot/initrd-install-xen'

# After installation boot, enable below 1 line

#bootloader='/usr/bin/pygrub'

extra='text'

memory=1024

vcpus=1

# After installation boot, disable below 1 line

disk=['file:/home/vmimg/centvdisk.img,xvda,w']

# After installation boot, enable below 1 line

#disk=['tap:aio:/home/vmimages/centvdisk.img,xvda,w']

audio=0

vif=['bridge=br0']

# After installation boot, disable below 1 line

on_poweroff='destroy'

on_reboot='restart'

on_crash='restart'

-----------------------------------------------------------------------------

* As for this process, U need to make root/swap partition manually

7. Create VM with xm command

 # xm create -c cent54domu.cfg => installation starts

   * If  reboot starts after installation, kill it!

 # xm destroy domain_number

 # cp cent54domu.cfg cent54domu_init.cfg

 # vi cent54domu.cfg => Do as the comment says & save it

 # xm create cent54domu.cfg

  * Now VM starts as a normal boot process

  * All done.
