Virtual Machine Maintenance Docs

The Developer VirtualMachine is built from a TurnkeyLinux Base Virtual Machine.

It is best if the VM is maintained using the original VirtualBox image & then re-exported to OVF

Test Sahana Eden.

clean

The following aliases have been setup:

alias w2p='cd /home/sahana/Desktop/web2py && python web2py.py -S eden -M'
alias update='cd /home/sahana/Desktop/web2py/applications/eden && bzr pull'
alias update_w2p='cd /home/sahana/Desktop/web2py && bzr up'
alias update_all='sudo apt-get update;sudo apt-get upgrade -y;cd /home/sahana/Desktop/web2py && bzr up;cd /home/sahana/Desktop/web2py/applications/eden && bzr pull'
alias clean="rm ~/.bash_history;cd ~/Desktop/web2py/applications/eden && rm -f databases/* && rm -rf cache/* && rm -f sessions/* && rm -f models/000_config.py && rm -f cron/crontab;sudo rm -f /var/log/*;sudo rm -f /var/cache/apt/archives/*;COLUMNS=200 sudo dpkg -l | grep ^rc | awk '{print $2} ' | xargs sudo dpkg -P"

Resume Uploads

If the scp upload fails, then can resume it using:

rsync -Pe ssh Eden-VM.zip flavour@eden.sahanafoundation.org:.

  apt-get install secure-delete
  sfill -fz /
  

Compress the VDI disk image:

• ​http://www.mdl4.com/2010/04/virtualbox-compact-a-vdi-in-ubuntu/

  C:
  cd "\Program Files\Oracle\VirtualBox"
  VBoxManage modifyhd c:\Users\%USERNAME%\.virtualbox\harddisks\Eden-Dev.vdi compact
