[Solved] Virtualbox 3 hard crash on Ubuntu 64 bit

[laurens.rietveld]

Trying to run Virtualbox 3 freezes my ubuntu and requires a hard restart. I installed the .deb package for 64 bit operating systems. My log file shows the following:

Code: Select all

I'm not sure why virtualbox tries to use 32-bit capabilities. Does anybody know why this happens?

Look in your computer bios and see if you have hardware-v turned on.
If you do not see it then you more than likely do not have it and since VBox requires hardware-v to run 64 bit software it will not work.

I indeed do not see any such thing as hardware-v in my bios. But isnt hardware-v a functionality to run 64 bit in a virtualized os?
The problem I have is that virtualbox (the 64 bit version) itself crashes, before I can even create a virtual machine. I tried the i386 .deb installation of virtualbox just to be sure, but indeed got an error message that the architecture I tried to install it on was wrong.

I have a related problem.

Whenever I enable VT-x/AMD-V (I have a core2 Quad CPU) the whole system instantly crashes as soon as I try to start the virtual machine.

This is true on two different (same type of computer) hosts, and with multiple virtual machines, linux and windows.

Update: new version of virtualbox saves the day . Updated virtualbox, and all was working properly
