Should I be Elsewhere for this???
« on: September 14, 2011, 10:12:21 PM »
Hi  to all,
I have been trying to get 64bit test3  installed into virtualbox latest, but no go.
It reports VT-x and AMD-V has been enabled but is not operational. Your 64 bit guest will not boot
Which is true!!
What must I do to get test3-64 installed in VirtualBox 4.1.2 =rxxxx??

From memory, you need a 64bit cpu, and need to enable hardware visualization support in the bios

EDIT
I just found this on the virtual box Q&As

Q: Does VB support 64 bit guests?
A: Support for 64 bit guests was introduced at version 2.0.0. If you wish to create 64 bit guests then we recommend that you upgrade to the latest version. Note that VirtualBox also supports 64-bit guest operating systems, under the following conditions:

    You need a 64-bit processor with hardware virtualization support (see User Manual chapter 1.2, Software vs. hardware virtualization (VT-x and AMD-V), page 10) and a 64-bit host operating system.
    NOTE: Since version 2.1.0, you can run 64 bit Guests while running a 32 bit Host. The prior requirement for Operating System is only for version 2.0.x. You still need the proper hardware.
    You must enable hardware virtualization through your BIOS; software virtualization is not supported for 64-bit VMs.
    Note: some HP BIOSES have a glitch, When You ENABLE VT-X/AMD-V, You DISABLE it, so do try both ways.

In addition to 7272andy post, in Virtualbox try using Settings > General > Basic in the drop down box make sure you have Linux 2.6 (64 bit) selected - see screenshot



Edit

If you also want to enable pae go to:

Settings > System > Processor and tick the box - see screenshot

In addition to this when I enabled it on a Dell I had to go int othe BIOS and enable it three times before it stuck.  Not sure why.  Have not had an issue since then though. 

Also, Gezza, what CPU do you have?   I can lookup to see whether VT-x support is available.
