In summary:
1. install everything on VM1. Then remove unnecessary files.
2. add a second virtual disk.
3. boot from a liveCD,such as Ubuntu desktop 8.0.4
4. partition the second hard disk and copy files to it. (/mnt is the second hard disk)
fdisk /dev/sda (and type 'p' to print the partition table)
fdisk /dev/sdb (and use the n, t, and w commands to recreate the same table)
mkfs.ext3 /dev/sdb1
mount /dev/sdb1 /mnt
cd / (target)
ls egrep -v 'procsyslost.found' > /files.txt
cp -a `cat /files.txt` /mnt
5. Install grub (mbr) to be bootable:
1) Type "grub" in a console
2) Type "root (hd1,0)", or whatever your harddisk + boot partition numbers are (my /boot is at /dev/sdb1, which translates to hd1,0 for grub).
3) Type "setup (hd1)", or whatever your harddisk No. is.
4) Quit grub by typing "quit".
6. shutdown VM. remove the first hard disk.
7. boot.

HowTo: Create a list of installed packages
I found out how to do this recently and thought it might be helpful to some people. To output this information to a file in your home directory you would use,

dpkg --get-selections > installed-software

And if you wanted to use the list to reinstall this software on a fresh ubuntu setup,

dpkg --set-selections

followed by

dselect

Install Flash player on Ubuntu 8.04 server
