VMware (Workstation, Player, Server) is a commercial virtualization system that emulates hardware resources allowing one computer to host a number of x86 architecture-compatible operating systems. The Player and Server versions are distributed free of charge (gratis). It runs on either Win32 or Linux host machines, allowing one to run Sugar images within the virtual machine. A Mac version is also available, VMWare Fusion, however this is not provided free of charge. A free 30-day evaluation is available, and free licenses are available for academic instruction and research use.

Software applications, such as the Sugar platform, may be deployed as VMware Virtual Appliances, which are one or more virtual machines pre-built, packaged, installed, updated, maintained, and managed as a unit.

Building a virtual appliance for the Sugar platform

Appliances from a live.iso file (No Persistence)

Make a new Appliance in VMworkstation with (minimal) hard disk
Set XXX-live.iso as CD in VMworkstation with a 0.1 GB Hard disk.
Boot and run VMworkstation, then shut down.
Copy contents of the new Appliance in the VMware directory a USB flash drive.
Copy XXX-live.iso file to the same USB drive.
Open this copied Appliance on the USB drive with VMWorkstation, and edit the location of the live.iso file to point to one on the USB stick, then close it.
Start VMplayer and open this Appliance from the USB drive, or any other VMplayer on any PC.
this appliance is just like a boot CD—it has no persistence—the system image is treated as a read-only file. (You are running the .iso image with VMPlayer.) The appliance file size is only slightly larger than the .iso file.

Boot this Appliance from a USB boot drive/stick (see below)

The system can be run on any PC without changing or accessing its primary hard disk.
Use it to run Soas .iso images on PCs lacking a CD-ROM reader but with a USB port.
Run Sugar on unbootable PC's using a VMPlayer application

Appliances with Persistence

VMWorkstation 6.5.2 with Fedora-11-Preview-i386-netinst.iso (need link)
Settings for VMWorkstation:
1. Create a new virtual machine
2. Typical
3. Installer disk image file:(Fedora-11-Preview-i386-netinst.iso)
4. Linux
5. Other linux 2.6xx kernel 8-GiB disk
6. Max Disk Size (GB) 8.0
7. Split disk into 2-GiB files
8. 512 kB memory.
Net install with network connection
Use entire disk
De-select Gnome Desktop
Customize now
Select Sugar Desktop (Only selection entered)
Set a root password (sugarroot?) and time zone
When finished (about 45 min on ??-kbyte/s cable)
Reboot, set user password (sugaruser?), shut down.
Clone and save clone on Desktop and use to load on 4-GiB SD or USB or make DVD (3.2-Gib files)
See note below to remove the Sugar user information and make the image ready for a new first user login. Original passwords for root and user (sugarroot/sugaruser?) entered during the install will remain and are needed for login & administration. This is required so that copies will have different identities.

Method to remove Sugar user information (from Dave Bauer VirtualBox/Preparing_a_disk_image).

Open Terminal
Terminal
rm -rf ~/.sugar (if distributing image)
su -
shutdown -h now

Alternatives

Fedora 11 Sugar Spin :http://spins.fedoraproject.org/torrents//F11-Preview-i686-Live-Edu.torrent see Fedora 11 below
SUSE Sugar Spin:(see section below)

Comments

Run on free VMplayer loaded on any PC with 512 kB of memory (256 kB required for VMplayer).
ADVANTAGE: No need to boot USB stick on problem machines.
Same machine can be used by a succession of students with their own copy of Sugar.
Students can take USB/SD drives home and run them on their own PCs.
Disadvantage: Have to install VMplayer on PCs

Two virtual machines on different PCs, each running NAT on same network, seem to cause "collisions" in jabber (Neighborhood View gets depopulated on both ???).

Logon screen allows user to switch session types:
- KDE
- Sugar
- Failsafe

Making VMPlayer using a Single 4-GiB USB boot stick and an Appliance on a second 4-GiB stick

On one 8-GiB stick with 2 partitions

Ubuntu 9.04 has a "USB Startup Disk Creator". I used a 8-GiB USB stick with 2 partitions to run a VMplayer Appliance on the Same Stick VMplayer WILL install on Ubuntu or Fedora 10, but NOT on F11 at this time. METHOD:

In PC running Ubuntu 9.04 (or running in VMworkstation6.5.2.)

Start Partition Manager

Delete existing partitions on USB [/dev/sdb?]
(BE CAREFUL TO BE LOOKING AT the USB drive and not your Hard Disk.)
Create a FAT16 2-GiB Primary Partition, set boot flag, and label it Ubuntu
Exit partition manager
Run USB Startup Disk Creator
Create USB, select: /dev/sdb1 "Ubuntu"
Select "Other" and find Ubuntu 9.04.iso (not live install) previously downloaded to Desktop
Create live usb on first partition.
Start partition manager again
(BE CAREFUL TO BE LOOKING AT the USB drive and not your Hard Disk.)
Create a FAT32 primary partition with the remaining, unformatted space on the USB drive, set boot flag, and label VM_Apps
Exit Partition Manager

Remove and reinstall USB stick

Two USB icons will appear
Cut and paste previously obtained VMplayer Appliance to VM_Apps

ReBoot PC with USB Stick

Start Firefox and download VMplayer (free) Linux xxxx.bundle
Place .bundle file in /tmp
su - command in /tmp
Enter password for root
Install bundle in /tmp ( ./ command as administrator. )

Run VMplayer Program

Start VMplayer
Choose VM_apps Icon and open VM Appliance file
Choose Gnome or Sugar as login, enter password
Initial Password for Sugar = sugaruser (change user name and password in live user)

Passwoord for root = sugarroot

Have Fun (Fedora 11 0.93 0.84-2)

Thus, with one 8-GiB USB stick loaded with Ubuntu 9.04 and VMplayer, plus the Appliance, a Student can carry the OS and a full copy of GNOME Desktop and Sugar on a single USB stick.
It is complicated to make, but simple to use and it works.

The Appliance can be loaded on a separate USB stick

Two USB/SD sticks (2 GiB Boot and 4 GiB or larger for the appliance)

This allows VMPlayer to be used by multiple students without rebooting the PC

Windows XP SP2

Loads and runs VMware virtual machine in Windows XP SP2 {tested on a Dell 2350 Tower}

Appliance (packaged virtual machine) transfered by DVD and loaded on Hard Disk.

Ubuntu 8.04 and 9.04

VMworkstation 6.5.2 can make virtual machine files in Ubuntu. VMplayer (available on line) will run these Appliances. The Appliance can be distributed then by copies on DVD to 4-GiB SD or USB drives or from future downloads from a Sugar Labs or other server.

Fedora 11

VMplayer will not load in Fedora 11 beta or Fedora Preview loaded with shell command; One gets "Unable to modify kernel" error and quits.

Spin of SUGAR F11 preview live

http://spins.fedoraproject.org/torrents//F11-Preview-i686-Live-Edu.torrent

It works well as a boot CD or as a 4-GiB Appliance for VMplayer.
It upgrades in VMplayer to F11 (Leonidas) after 167 files +45 updates as of 5/30/2009.
It contains version 0.84.2 Sugar and Xfce 4 Desktop with a KDE switcher.
It installs nicely in the normal manner.

See the procedure above to make a VMplayer on a USB boot stick run the latest version of the Sugar platform in Fedora 11 as an Appliance.

Fedora 10

VMplayer can be loaded in Fedora 10 and used to run a VMplayer Appliance of Sugar platform based on Fedora 11.
The Sugar platform included in Fedora 10 is not the current version.

openSUSE

SUSE Sugar page: http://en.opensuse.org/Sugar

(See: nubae and cyberorg on #irc #sugar #opensuse-edu for details.)

SUSE is building and hosting appliances at these sites for downloading.

live CD with a very large number (~50) of activities

installs to Hard Disc

Sugar terminal:

su -


yast2 live-installer

add user

yast2 users

change networking

yast2 lan

wireless networking

yast2 lan

latest USB .raw file contains wireless drivers.

(EeePC900 booted from 2-GiB SD card works on Apple Airport extreme after this was done.)

need to switch networking out of network manager; edit and add wireless wlan wireless wlan0; and enter info on encrypted or open, and if WEP, SSID plus WEP Key information.
select the new wlan0, then select "manage with network manager".
Reboot USB.
Go to drop down box on network and delete network history. Be sure to have radio box checked.
Reboot again, On F1 neighborhood should see circles for wireless network connections.
Mouse over the one you want to use and enter passwords if requested on drop down box

This is a preliminary writeup please edit if you find a faster way.
