Ticket #9105 (closed defect: duplicate)
No 64-bit support in Linux 3.0 kernel
|Reported by:||rameijer||Owned by:|
When starting VirtualBox 4.0.8 on Linux 3.0 AMD64 I get the following error box:
VT-x/AND-V hardware acceleration is not available on your system. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot.
In the log I see the following:
HWACCM: The host kernel does not support VT-x -- Linux 2.6.13 or newer required!
Apparently, Linux 3.0 is not being recognised as newer than 2.6.13.
virtualbox-4.0 4.0.8-71778~Ubuntu~natty Linux aurora 3.0-1-generic #2-Ubuntu SMP Wed Jun 15 20:28:47 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux Ubuntu 11.04
I can run everything without problems with Linux 2.6.39. Only on Linux 3.0 I experience problems.
The same thing happened with the NVIDIA driver. I had to update a kernel version check (along the lines of, "if kernel_version < 2.7.0 then kernel=2.6" was changed into "if kernel_version < 3.1.0 then kernel=2.6") in the source code to make it work.
I suspect a similar change needs to be made in the VBox source code.
