Everything I am hearing about the upcoming Lucid Lynx release of Ubuntu sounds really great. I just grabbed Alpha 3 from the Ubuntu site and was a little dissappointed to see it hang as soon as I selected “Install Ubuntu”. The fix is to turn off the ACPI option in the system settings for your VM.
The side-effect of this is that the virtual machine will no longer close the window and disappear when you shut it down. C’est la vie.
From there the installer started up fine, but it hung again when I tried to update the installer. When I skipped the update it installed without any other problems. Thats what worked for me on Virtualbox 3.08 OSE.
UPDATE: This issue still seems to be effecting the new Lucid Beta 1…
