[Bug 510571] Re: Lucid guest won't boot with acpi in virtualbox

@Mark
What version of virtualbox is this?
If host is Lucid with matching virtualbox, it will likely be a separate bug, since this particular specific bug should be fixed. Please report a new one.

If host is Karmic with matching virtualbox, this bug hasn't been backported yet, still awaiting word from the SRU team on that.
Although similarly, this bug and fix is related to the kernel not being able to /boot/, anything past that I would assume to be a separate issue.

Bug description:
Lucid is unable to boot as a guest operating system in VirtualBox when having acpi enabled.
Applies to Karmic & earlier versions of VirtualBox

------

TEST CASE:
0.1 Boot a pre-Lucid release of ubuntu
0.2 Install VirtualBox
1. Create a new virtual machine in VirtualBox
2. Attach a Lucid liveCD (e.g. beta1) and start the virtual machine
* The machine is unable to boot
! Expected is that the machine should be able to boot

Workaround:
Either disable acpi in the VirtualBox settings, or use acpi=off as a kernel parameter when booting.

Impact:
This affects the testing of Lucid as well as running any distributions with a newer kernel.
The number of affected users can be expected to increase

Scope:
Issue first triggered on kernel 2.6.32-11 in Lucid and is present on all later versions.
This seems to apply to all versions of VirtualBox prior to 3.1.4 beta (OSE and PUEL) when booting Lucid (or any other system with a newer kernel). That is, all versions prior to Lucid's (Karmic & Jaunty confirmed)

Fix:
Changesets r26129 (http://www.virtualbox.org/changeset/26129) and r26130 (http://www.virtualbox.org/changeset/26130) from upstream SVN fixes this bug, and testing of these through patched PPA package (https://launchpad.net/~arand/+archive/virtualbox) seems to be successful
