virtualbox.org

My host OS is Windows XP Pro SP3, and my guest OS is Ubuntu 10.10. I am using VirtualBox 3.2.10. During boot-up of the guest OS, I get the following error. The image then appears to boot successfully.

[ 15.459985] piix4_smbus 0000:00:07.0: SMBus base address uninitialized - upgrade BIOS or use force_addr=0xaddr

Preferably, it would be nice to boot with zero errors, so how can I make this thing go away? Or, if there is a problem, how can I fix it? Thanks.

This is just a warning and does not impede the operation of VirtualBox or the guests.

How can I make the warning go away, then?

The Ubuntu forums has a way to do this although from what I read I would not use it. The warning is just not a problem, and the drastic way to get rid of it may cause other problems.

A link would be helpful.

I think if you are hell bent of getting rid of the message you will need to make a custom kernel that doesn't contain PIIX4 module. https://help.ubuntu.com/community/Kernel/Compile

The message persists even if you remove the PIIX4 or replace it with ICH6 controller from VB.

SMBus is where all the sensors like temperature, rpms etc are based off.. obviously vb won't have them!
