virtualbox on Ubuntu 11.10 - guest windows 7 resolution problem - copying text to clipboard

1. When i installed win 7 as guest in virtualbox on my ubuntu 11.10, i was not able to set proper resolution, either it was too small or it was too large, that was not fitting the whole screen properly.

2. i was not able to copy text from virtual machine to clipboard

solution: install guest additions

how to : launch your virtual windows 7. on top menu, under devices, click "install guest additions"

this will first try to find VbGuestAddtions iso under your linux file systems. if it fails, it tries to fetch from web. if that also fails it will throw error that it is not able to find the iso file.

solution: do "sudo apt-get install virtualbox-guest-additions-iso" this will install manually.
then go to virtual win 7. and click install guest additions.

restart your vm. Now you should be able to toggle between full screen and minimized screen properly.

Also now you should be able to copy text between your VM and host machine properly.
