Hi. Im getting the error message while in Windows 8 OS trying to launch Virtual box so I can run SAS University Edition on it. Its saying the following:

VT-x/AMD-V hardware acceleration not available on your system (VERR_VMX_NO_VMX)
Certain guests (OS/2 and QNX) require this feature and will not boot without it.

I need this to work for class.

Does anyone have a work around solution?

1) 64-bit guests need hardware-virtualzation enabled in the hosts bios.
2) when creating the 64-bit guest you must select 64-bit in General -> Basic -> version.
3) If running Windows as host you must make sure hyper-v or xp mode is not enabled on the host. MS does not play well and wants it all.

Perryg,
Will it work then if as a 64-bit guest I select 64-bit in General -> Basic -> version?
Thanks!

If all three steps are followed then yes it should work.

Perryg,
Thanks.
That sounds like it should work except I am already set-up as a 32 bit system and it won't let me change it in the settings.
I don't want to start over.

Sadly you really can not just change the setting if you think you want to change to a 64-bit guest. If however it is the 32-bit guest stating you need VMX enabled that would be strange indeed.

Post the guests log file ( as an attachment ). Right click on the guest in the Main Manager then click show log. Save and post as an attachment. Compress if it is too large to post.

Then I can better advise you.

Perryg,

I have a attached a log file.

I hope this is the correct one.

Please advise.

Thanks!

If you click the link below you will see that your CPU does in fact support VT-x ( VMX mode )

But this is why only 32-bit guests are avaiable.

Just enable hardware virtualization in your bios and you will be able to install 64-bit guests. Unfortunately you can not change a 32-bit guest to 64-bit guest as they use different kernels.

Can you direct me to specifically enable the hardware virtualization in the bios?

Now that you mention it, I did see an error message regarding a missing kernel.

Thanks!

You would need to ask your PC manufacture how to do that. Almost all I know of post the instructions in the owners manual or website.

I will look into it.

Thanks Perryg!
