Hello,
I am trying to build a windows 7 guest using virtualbox-ose-3.1.8. When
starting the virtual machine to install the OS, I get the warning:
"VT-x/AMD-V hardware acceleration has been enabled, but is not
operational. Your 64-bit guest will fail to detect a 64-bit CPU and will
not be able to boot.
Please ensure that you have enabled VT-x/AMD-V properly in the BIOS of
your host computer."
I have enabled the following in the BIOS:
Intel(R) Virtualization Technology
Intel(R) VT-d Feature
I have not created a KVM module in the kernel (using
gentoo-sources-2.6.34-r12). Is this needed?
Couple of things to check.
1. Make sure you've turned on all the related BIOS features that may be
related. Sometimes it's more than one or two depending on the manufacturer.
2. Verify that your chip supports 64bit VT. I found out recently that my
Intel T6600 while 64bit can only run 32bit guests.
3. You're running vbox 3.1.8 which is stable for x86 while vbox 3.2.12
is stable for amd64. Is your host OS 32bit?
