= Virtual Machine =

== Summary ==
This virtual machine has been built to allow Developers to get operational quickly:

It is in the Open Virtual Machine format for use in either [http://virtualbox.org VirtualBox] or [http://vmware.com VMWare].

It is currently running the Ubuntu 10.04 OS with Web2Py-r2717, Eden-r1560 & Eclipse 3.5. (Note that both Web2Py & Eden are very old & should be updated before development starts!)

== Usage Notes ==

=== Introduction ===
The dev env virtual machines for Virtualbox and VMware are based on a [BluePrintlivecdinstaller blueprint] and are configured to use about 512MB of RAM. The virtual disk is configured to expand to 20GB. The virtual machine is built on [http://www.turnkeylinux.org/core TurnKey Linux's Core], which in turn is based on Ubuntu 10.04 (Lucid -- the most recent long-term support release). The machine runs [http://code.google.com/p/shellinabox/ Shellinabox], [http://www.webmin.com/ Webmin], and SSH/sftp as services from startup.

The development environment is configured to launch [http://lxde.org LXDE], a lightweight desktop environment after the first boot. From LXDE, Eclipse with Pydev, Firefox with Firebug, iPython and irssi are accessible.

After installation you will need to configure the included !Eclipse/PyDev:
 * DeveloperGuidelinesEclipse#Configuration

=== Getting Started ===
 1. [InstallationGuidelinesVirtualMachine#download Download] the Image
 2. Uncompress the image: [http://www.7-zip.org/download.html 7zip] is a very effective FOSS tool for systems running Microsoft OSs. In Linux distros, the following command should work:
{{{
tar xvzf eden-dev-env.tar.gz (for example) #extract to current working directory
}}}
To run the image, you need to install either !VirtualBox or VMWare:

==== !VirtualBox Installation ====
 3. Download [http://download.virtualbox.org/virtualbox/vboxdownload.html VirtualBox]
 4. Install !VirtualBox
 5. Import the Virtual Appliance:
 * File menu | Import Appliance 
 * Click on the Choose button and navigate to and select the uncompressed image (the .ovf file)
 * Next 
 * Accept the default appliance options unless you have a reason to make a specific change
 6. The VM will appear in the left window pane, and the settings will appear in the right. Scroll down on the right side until you see "Network." Click network to specify the NIC (e.g. switch to wireless) and choose between bridged and NAT mode.
 7. Start the Virtual Appliance by double-clicking the icon on the left.

===== Troubleshooting !VirtualBox =====
It's been reported that VMs derived from patched ISOs, as these have, may have network problems. Read [http://www.turnkeylinux.org/docs/virtualization/udev-persistent-net-generation this] article to work the solution. Contact us if you still have problems. There's no way for us to test whether there will be problems in your case.

 4. Select "Use Existing Hard Disk"; choose !NewDev.vmdk. Click Next. Click finish.
 5. Selct !NewDev on the left; scroll down to network on the right. Ensure the appropriate network adapter and settings for your circumstances are selected.

''Boot Process Halts''

'''Scenario'''

When started in !VirtualBox OSE 3.1.6, !NewDev boot process halts at "Starting Initialization Hooks".

'''Solution'''

Coming soon.

==== VMWare Installation ====
''Import''

To import the download VM into VMware (e.g. Fusion), use the following steps.
 3. File > New
 4. Click Continue without disc
 5. Select Use an existing virtual disk
 6. Select !NewDev.vmdk
 7. Select Make a separate copy of the virtual disk
 8. Click Choose

Remember to install the Linux VMware Tools after starting up the Eden machine using Virtual Machine > Install VMware Tools
{{{
sudo su -
./vmware-install.pl
}}}
And accept all the default options

''VMWware Converter''
Version 4.0.1: "Cannot be deployed on the target hardware"

''VMware Player 3.1.1 (Ubuntu)''

===== Troubleshooting VMware Tools Install =====
 * Open LXTerminal and browse to the folder containing vmware-install.pl.
{{{
pwd #displays the current location in the filesystem
cd /absolut/path/to/folder # change directory to the one containing vmware-install.pl
sudo ./vmware-install.pl #start installation script
}}}
 * Download Build Tools
 *Option 1: Open Synaptic in the LXDE menu, update, then search for build-essential
 *Option 2: Open LXTerminal and install build-essential from the command line:
{{{
sudo apt-get update
sudo apt-get install -y build-essential
}}}

=== User Accounts ===
Root password is set through a dialog box on first boot.

The user named ''dev'' should have it's password set from the command line when first boot is complete with the command:
{{{
passwd dev
}}}

You should then reboot & use the Graphical User Interface to login as the user 'dev'.

Web2py administration password is set during the debugging process with either of the following commands and arguments, both of which would set the admin password to "admin":
{{{
/home/dev/web2py.py -a admin -i 127.0.0.1 -p 80

/home/dev/web2py.py --password admin -i 127.0.0.1 -p 80
}}}

Credentials for the previous version:
||Username: ''dev''||||Password: ''eden''||
||Username: ''root''||||Password: ''root''||

==== Root User ====
There is no practical reason to login in as ''root''.

If one needs root privileges, ''dev'' can have them. The following lines offer strategies for escalating ''dev''s privileges from the command line. Start LXTerminal and use one of the following strategies.
{{{
sudo command-to-execute-as-root #executes on command or pipeline of commands as root.
su - root #Switch user to root
command to execute #1 command executed as root
command to execute #2nd command to execute as root
command to excecute #3rd command to execute as root
exit # Exit using root's account and shell
}}}

==== Secure the System ====
Change the default passwords to secure the system.
Log in as ''dev'', start LXTerminal, and enter the following commands to change passwords:
{{{
sudo passwd root #interactive change root password
passwd #Interactive change dev password
}}}
It's also important to keep get security updates from online; login as ''dev'' and execute the following:
{{{
sudo apt-get update
sudo apt-get upgrade
}}}

=== Filesystem ===
Web2py is located in /home/web2py. Eden is located in /home/web2py/applications/eden. Eclipse and PyDev are preconfigured with this information.

=== Scripts ===
/usr/local/bin contains three helpful scripts. To run them, start LXTerminal (in the accessories menu) and simply enter the commands as demonstrated below. They are in all users' paths, so may be executed from any working directory.
==== Update web2py ====
Enter the command with or without a revision number, as demonstrated below:
{{{
update_web2py 2717 # updates web2py to revision 2717
update_web2py # updates web2py to current revision
}}}
==== Update Eden ====
{{{
update_eden 1560 # updates Eden to revision 1560
update_eden # updates Eden to current revision
}}}

==== Web2Py shell ====
launch a Web2py shell in the Eden environment
{{{
import_eden
}}}
NB Script seems oddly named

== Troubleshooting older Releases ==
Note: If you get a ticket when running the application for the 1st time with a message like "!OperationalError: Cannot add a UNIQUE column" then you need to stop the debugger, delete the contents of the databases folder & then start debugging again (there was an old database accidentally left on the system which cannot be auto-migrated - a new image without this issue has been uploaded):
{{{
rm -rf ~/Desktop/web2py/applications/eden/databases/*
}}}

If you get an error like "!AttributeError: SQLCustomType instance has no attribute 'startswith'" then:
{{{
cd ~/Desktop/web2py/gluon
rm sql.py
wget http://eden.sahanafoundation.org/sql.py
}}}
Then can proceed as above: Stop Eclipse, empty databases folder & restart Eclipse

A new image without this issue has now been uploaded.
