Steps:

0. [IF NECESSARY] Preparation
    * Modify /usr/lib/python2.4/site-packages/grub/GrubConf.py
          - Refer to Refs. [1-3]
    * Create Ubuntu 14.04 template
          - Refer to Ref. [4]
    * Make ISO install available (after the three commands given in Ref. [4])
          - xe template-param-set other-config:install-methods=cdrom,http,ftp uuid=$NEW_TEMPLATE_UUID

1. New VM
	* Two choices (I didn't try the second one):
          - Install from ISO Library: ubuntu-14.04.1-server-amd64.iso
          - Install from URL: http://ftp.twaren.net/Linux/Ubuntu/ubuntu/
	* 2 vCPUs
	* 2048 MB RAM

2. Manually or automatically configure the IP
	IP: 10.???.???.??? (DHCP: 10.0.0.1 -- 10.0.0.255)
	Netmask: 255.0.0.0
	Gateway: 10.255.255.254
	Name server: 8.8.8.8

3. Make a separate /boot partition
	A. Partition method: Manual
	B. Virtual disk 1 (xvda) (assume to be 8GB, which is the default value for Ubuntu)
	C. Create new empty partition: Yes
	D. Create new partition -- /boot
		a. 256MB
		b. Primary
		c. Beginning
		d. Use as: Ext3 journaling file system <-- "Ext3" is IMPORTANT
		e. Mount point: /boot
		f. Reserved blocks: 1%
		g: Bootable flag: on
		h: Done setting up the partition
	E. Create new partition -- /
		a. 6GB
		b. Primary
		c. Beginning
		d. Use as: Ext4 journaling file system (default)
		e. Mount point: / (default)
		f. Reserved blocks: 1%
		g: Bootable flag: off (default)
		h: Done setting up the partition
	F. Create new partition -- swap
		a. 2.3GB
		b. Primary
		c. Use as: swap area
		d: Done setting up the partition
	G. The result:
		Virtual disk 1 (xvda) - 8.6 GB Xen Virtual Block Device
		>	#1  primary  254.8 MB  B  f  ext3    /boot
		>	#2  primary    6.0 GB     f  ext4    /
		>	#3  primary    2.3 GB     f  swap    swap
		fdisk -l /dev/xvda
		    Device Boot      Start         End      Blocks   Id  System
		/dev/xvda1   *        2048      499711      248832   83  Linux
		/dev/xvda2          499712    12218367     5859328   83  Linux
		/dev/xvda3        12218368    16775167     2278400   82  Linux swap / Solaris
	H. Finish partitioning and write changes to disk
	I. Yes

4. No automatic updates

5. Select only "OpenSSH server"

6. Install GRUB boot loader to MBR: Yes.

7. UTC Time: Yes.

8. Boot, login, and become root. Command:
	sudo -s

9. [2] Update /etc/fstab. Two ways to do it.
	A. Use sed to do the job. Command:
		cd /etc
		mv fstab fstab.orig
		cat fstab.orig | sed -e "s/errors=remount-ro/noatime,nodiratime,errors=remount-ro,nobarrier/" | sed -e "s/defaults/nobarrier/" > fstab
	B. Or, manually replace
		errors=remount-ro
	with:
		noatime,nodiratime,errors=remount-ro,nobarrier
	and
		defaults
	with:
		nobarrier
	to fix the read-only file system issue.

10. Reboot. Command:
	sync ; sync ; reboot

11. Boot, login, and become root. Command:
	sudo -s

12. Install PV Linux kernel. Command:
        apt-update
	apt-get install linux-virtual linux-image-virtual linux-headers-virtual

13. Reboot to check if everything is ok. Command:
	sync ; sync ; reboot

14. Boot, login, and become root. Command:
	sudo -s

15. Select xs-tools.iso from "DVD Drive 1"

16. Mount XenServer Tools. Command:
	mount /dev/xvdd /mnt
	mount: block device /dev/xvdd is write-protected, mounting read-only

17. Install XenServer Tools. Command:
	cd /mnt/Linux
	dpkg -i *amd64.deb
	cd /
	umount /mnt
	(It's ok to fail.)
	sync ; sync; reboot

18. Eject xs-tools.iso from "DVD Drive 1"

19. Upgrade installed software
	apt-get upgrade
