Hi!

Since i've updated from VirtualBox 2.1.4 x64 to VirtualBox 2.2.0 my x64 guests doesn't get started anymore. I've get this message when i try to start them:


As descriped in the help of VB, i activated VT-x in the settings of my VM.



With 2.1.4 my x64 guests (WinXP Pro x64 and Win7 x64) worked without any problems. After updating to 2.2.0 they won't start anymore. VT-x is activated in BIOS. There are no problems/errors occured while the install of VBox 2.2.0. I also can't install new x64 guests. The host is WinXP Pro x64 SP2.

Does anyone have suggestions?

I know, begging for answers sucks - but I really need help.
x64 guests still doesn't work, I don't understandy why.

I'd suggest to go back to 2.1.4 and open a bug ticket on bugtracker if this isn't listed there.

Try reinstalling VBox and this time do it as administrator (right click the install file, then left click run as... Select admin)
Select the repair function and see if this helps.
You will need to reboot after the install, and you will also need to reload the guest additions.
Before starting the guest make sure that the VT-x has a check mark and try to open the guest.

Edit: I see that vbox4me responded as I was hitting the send key. Still would not hurt to try this also.

Haha, begging works

Thanks for answers - but it's soooo typical: After starting the begging here I found the solution deep in google results with a very complex search term . It's a bug in BIOS of the abit mainboard. I had to restart pc and deactivate VTx in BIOS. Then I had to shut down the PC completely (& plug it off) - after a few seconds I had to start the PC and reactivate VT-x in BIOS and restart the PC again. Now it works

Stupid BIOS.
