How can I run Unity in a virtual machine?
11.04 comes with unity interface. I would like to test 11.04 without installing it on a hard drive. Will it be possible?
A useful approach to testing the next releae, 11.04 is to create a live Ubuntu system on a USB memory stick from the daily builds:
Unity is not the default desktop environment yet, but is scheduled to be so by Alpha1 on the 2nd December as far as I understand the release schedule: https://wiki.ubuntu.com/NattyReleaseSchedule
As well as testing Ubuntu a Live USB stick, you can also use that live USB stick to install Ubuntu 11.04 onto a second USB stick, selecting manual partition during the install.
You can also use TestDrive to automate testing when Ubuntu 11.04 Unity desktop does work in VirtualBox.
