64 bits guests are not allowed
Hi. I am an Ubuntu 9.04 64 bits user.
I did installed VirtualBox from the repositories an AFAIK it should support 64 bits guests, but it doesn't.
I did allowed the virtualization in bios setup, virtualbox kernel modules are operating and the system kernel support virtualization is configured as required.
My system is and Phenom Quad with 16 Gb., and my question is if the Virtual Box version installed from the repositories supports 64 guests.
Thx.

Re: 64 bits guests are not allowed
Version 2.2.0 has it all in one download.
Previous versions you had to download the 64 bit version or the 32 bit version separately.
On some PCs the CPU might be 64 bit and the Motherboard does not truly support it, or the Bios does but needs to be updated.
So contacting the manufacture may be needed to be needed to determine the truth.
For VirtualBox to be able to use the 64 bit option it must have VT-x/AMD-V turned on in the bios.

Re: 64 bits guests are not allowed
Thanks for your answer Perryg.
I'm beginning to suspect that motherboard is not fully allowing virtualization, but the system work in 64 bits mode.
But, I need a confirmation on VBOX 64 bits guests virtualization capability for the repositories 2.2 versión. Thx.

Re: 64 bits guests are not allowed
I am having a similar problem. I have a new Dell E6500 laptop, which seems to be supporting 64-bit fine. I have enabled the Virtualization in the BIOS and I have turned on:
VT-x/AMD-V, Nested Paging, and PAE/NX in the General machine settings.
But, when I try to boot up a 64-bit ISO I get a warning that my CPU is only 32-bits.
I'm running the standard virtualbox-ose package from Ubuntu 9.04 (Jaunty Jackalope),
which seems to be version 2.1.4_OSE
Is there anything else I can check to see that I'm fully 64-bit enabled? I know this isn't the newest vbox, but
thought it should still work.

Re: 64 bits guests are not allowed
Check the manual and VirtualBox FAQ. They both say to check these things:
- BIOS
CPU
VM Settings
Other Virtualizers that might use hardware virtualization

Re: 64 bits guests are not allowed
As I stated in my original post,
My question was for anything *else* I might have missed, or possible confirmation that it should work with the above settings.
Can anyone confirm running a 64-bit guest OS on this hardware?
- I have enabled the appropriate Virtualization settings in the BIOS
My CPU is 64-bit (Intel Core 2 Duo - P8600)
I turned on the VT-x, AMD-V setting for the VM

Re: 64 bits guests are not allowed
Just a thought here.
You could contact your system provider and ask them if the unit you actually have will work with a 64 bit visualizer.
Might be more definitive than what anyone will tell you.

Re: 64 bits guests are not allowed
On some Intel boards, the BIOS setting is the reverse of what it says. Turning it ON actually turns it OFF. You wouldn't be the first.

Re: 64 bits guests are not allowed
I tried with the BIOS settings both ways on the Dell E6500.... since I can't get it to work either way, I can't say for sure which setting is really *on*.
According to: http://ark.intel.com/cpu.aspx?groupId=35568
The P8600 has Intel Virtualization and is 64-bit.

Re: 64 bits guests are not allowed
My friend, that is your CPU. My CPU is also supposed to work but come to find out my motherboard does not support it to the point that it will actually work. That's why I suggested that you contact Dell and ask them straight up will this work? While you have support they can tell you what if anything else you will need to do. Puts the ball in their court so to say. Of course this is only a suggestion, but that is where I would go. I have had Dell computers and they do not always work like I wanted them to or as they stated when purchasing.

Re: 64 bits guests are not allowed
Since this is done on a Linux Host, check /proc/cpuinfo, there should be VMX or SVM in the flags. If it's not, then you don't have VT-x/AMD-v.

Re: 64 bits guests are not allowed
yep, I did that.. I have the vmx flag in /proc/cpuinfo.
However, that flag is on whether or not the BIOS setting for Virtualization is enabled.
SOLVED! -- The Dell E6500 BIOS has three settings for Virtualization Support:
Virtualization -- Enable Intel Virtualization Technology -- on
VT for Direct I/O -- Enable VT for Direct I/O -- on
Trusted Execution -- "specifies whether a Measured Virtual Machine Monitor (MVMM) can utilize the additional hardware capabilities provided by Intel Trusted Execution Technology. The TPM, Virtualization Technology, and Virtualization Technology for Direct I/O must be enabled to use this feature" -- off
If I turn on the Trusted Execution flag, then I get the virtualbox warnings about only having a 32-bit architecture. With it off, things seem to work OK. This was unexpected behavior to me.... I have the TPM stuff turned off in the Security portion of the BIOS. I would have expected this to effectively be a don't care..... guess not. If I ever get around to messing with TPM, maybe I'll try it
