- for RHEL6, clear the old interface/device name

===================
For XenServer:
For XenServer:
- get CD Depository, tar of the old server
- create new VM, choose "Other install media"
- highlight the new vm, under "Storage" tab, select the created virtual disk, under Properties,highlight the last entry on the left panel "vm name(Device 0,(Read/Write)". Change the "Device Position" would change the device name "/dev/hda"
- boot with redhat with "linux rescue"
sh-3.2# fdisk -l #confirm the device
sh-3.2# fdisk /dev/hda # create 3 partition 1:100m for /boot, 2:swap, 3:root
# make sure the swap partition is type 82 (linux swap)

- modify boot/grub/device.map; grub.conf (make sure root=/dev/hda3); etc/fstab; etc/hosts; etc/sysconfig/network; etc/sysconfig/network-script/
(/etc/ntp/step-tickers)
- reboot to "linux rescue" mode again, system would find existing linux partition and mount it under /mnt/sysimage
sh-3.2# chroot /mnt/sysimage
sh-3.2# grub-install /dev/hda
sh-3.2# chkconfig network on
Then force reboot in citrix
- remove packages: "hp-snmp-agents hpacucli hp-health"
- install package: tcsh, OpenIPMI, OpenIPMI-libs
