[Xen-users] HOWTO: Compiling openiscsi and XEN 3.2 to work with each other

["Daniel Schwager" <Daniel.Schwager@xxxxxxxx>]

####################################
##  HOWTO Installation openiscsi for XEN
####################################

####### normal XEN-installation
 yum install hgsvn dev86 transfig openssl-devel xorg-x11-proto-devel texi2html 
pciutils-devel pciutils # fedoracore8

 cd /usr/src
 hg clone http://xenbits.xensource.com/xen-3.2-testing.hg
 xen-3.2-testing.hg/
 
 make -j8 world
 make -j8 install
 depmod 2.6.18.8-xen
 mkinitrd  /boot/initrd-2.6.18.8-xen.img 2.6.18.8-xen

 # modify menu.lst .... please adapt to your root-filesystem !!
 emacs -nw  /boot/grub/menu.lst
 title (2.6.18-8-xen3.2.testing-20080521)
        root (hd0,0)
        kernel /xen-3.2.1.gz  dom0_mem=512M
        module /vmlinuz-2.6.18.8-xen ro root=/dev/VolGroup00/LogVol00 rhgb quiet
        module /initrd-2.6.18.8-xen.img


 # REBOOT into you new xen-kernel (important !)

######## openiscsi build
b) additional building "clean xen-linux tree" (!!!!) for compiling openiscsi 
later 

 # Compile xen with "normal" tree
 cd /usr/src/
 hg clone http://xenbits.xensource.com/linux-2.6.18-xen.hg
 cd linux-2.6.18-xen.hg
 cat /proc/config.gz |gunzip >.config
 make -j 8

 # Compile openiscsi
  wget http://www.open-iscsi.org/bits/open-iscsi-2.0-869.tar.gz         # oder 
neuer
  tar xfvz open-iscsi-2.0-869.tar.gz
  cd /usr/src/open-iscsi-2.0-869
  make KSRC=/usr/src/linux-2.6.18-xen.hg
  make KSRC=/usr/src/linux-2.6.18-xen.hg install

 # for some reason it do install into /lib/modules/2.6.18/, no idea why, so
 unalias cp
 cp -a /lib/modules/2.6.18.8/kernel/drivers/scsi/libiscsi.ko 
/lib/modules/2.6.18.8-xen/kernel/drivers/scsi/
 cp -a /lib/modules/2.6.18.8/kernel/drivers/scsi/iscsi_tcp.ko 
/lib/modules/2.6.18.8-xen/kernel/drivers/scsi/
 cp -a /lib/modules/2.6.18.8/kernel/drivers/scsi/scsi_transport_iscsi.ko 
/lib/modules/2.6.18.8-xen/kernel/drivers/scsi/
 
 # REBOOT HERE NEEDED

### Check system

# discover
  iscsiadm -m discovery -t sendtargets -p <IP> 3260
# login
  iscsiadm -m node -T <targetname> -p <IP> -l
# logout
  iscsiadm -m node -T <targetname> -p <IP> -u

.. here we are
