I can't run VirtualBox on Ubuntu Linux 11.04. I've installed the following packages:

ii  virtualbox-guest-additions   4.0.4-1                guest additions iso image for VirtualBox
ii  virtualbox-ose               4.0.4-dfsg-1ubuntu4.1  x86 virtualization solution - base binaries
ii  virtualbox-ose-dkms          4.0.4-dfsg-1ubuntu4.1  x86 virtualization solution - kernel module sources for dkms
ii  virtualbox-ose-fuse          4.0.4-dfsg-1ubuntu4.1  x86 virtualization solution - virtual filesystem
ii  virtualbox-ose-guest-utils   4.0.4-dfsg-1ubuntu4.1  x86 virtualization solution - non-X11 guest utilities
ii  virtualbox-ose-guest-x11     4.0.4-dfsg-1ubuntu4.1  x86 virtualization solution - X11 guest utilities
ii  virtualbox-ose-qt            4.0.4-dfsg-1ubuntu4.1  x86 virtualization solution - Qt based user interface

When I run VirtualBox as my user stivlo the QT interface starts, I press New, then Next, I write "test" in the Name field, "Linux" in the Operative System field and select "Linux 2.6" for the version and press Next.

In memory I leave the default 256Mb and press Next. In Virtual Hard Disk, I leave "Boot Hard Disk" checked and also "Create a new Hard Disk" selected and hit Next.

Then Next again in the splash screen for the Create new Hard Disk wizard. As Hard Disk Storage I leave "Dynamically expanding storage" selected and hit next.

In location I write test-hd and leave the size as 8GB and hit Next and press Finish and Finish again.

I get the following message:

Failed to create a new virtual machine test. Runtime error opening '/home/stivlo/.VirtualBox/VirtualBox.xml-tmp' for reading: -38 (Access denied.). /build/buildd/virtualbox-ose-4.0.4-dfsg/src/VBox/Main/src-server/VirtualBoxImpl.cpp[3302] (nsresult VirtualBox::saveSettings()).


Result Code: 
NS_ERROR_FAILURE (0x80004005)

I think you must have run virtualbox as root at some point.

Can you post the response to

ls -la /home/stivlo/.VirtualBox

If the owner is root, then you can just do

sudo chown stivlo /home/stivlo/.VirtualBox -R

bingo, the owner was root, thank you! – stivlo Sep 30 '11 at 7:21
