Virtualization on Lenovo T510 (4313CTO)

[prabhatnath]

Hello Friends,

I am using this laptop since several month and was interestered to try Virtualization now.

When I try to install any guest OS Like Windoes 2008 R2 or Windows 8 Consumer Preview x86 the virualization software (VMWare Client or Sun Virtual BOX) does not allow me to do so by telling that please enable Virtualization from BIOS.

But in the laptop BIOS already these values are enabled, then why any virtaulization aplication cant read that?

Details:

System:  Lenovo T510 (Model = 4313CTO)

Bios Ver: 1.48 (6MET88WW) Date:  2011-11-28.

These details are enabled in BIOS under CPU menu:

1) Intel Hyper-Threading = Enabled

2) Intel Virtualization = Enable

3) Intel VT-d = Enabled

Please advise how can i take advanateg of virtualization on this laptop.

Thanks.

Hello and welcome,

Have you done a cold reboot (full shutdown, then power u) since enabling VT?

IIRC, it won't be seen by the virtualization software until that happens.

BTW, I've had very good luck with VMWare Player 3.  Even running Android and Windows 8 side-by-side

Hello zoltanthegypsy,

Thanks for your input.

Yes I have done changes in BIOS and then restarted and seen that did not worked, so shutdown PC and started but still no luck.

In BIOS the values show correct and enabled. Not sure why from Virtualization application cant see that.

Any other stuffs I should do?

Thanks,

Prabhat

Hey prabhatnath,

Here's another thing to try:  if VT was already enabled before you started this project, try turning off all VT options in BIOS, and shutting all the way down.  Then start up, go to BIOS, enable VT, save and exit, let the machine boot, then shut all the way down again.  Somehow the VT settings aren't recognized properly unless the are enabled after a clean OFF state, I guess.

You may also need to remove the battery between the power off, power on cycles.  This is from another thread that I should have remembered. Sorry about that

HI zoltanthegypsy,

Thanks for the hint. That actually worked and I can now install Win8 on VMWare .

Also I came to know that Intel TXT should be disabled to ensure Virtualization working. So this may help other having similar issue.

So I disabled ALL virtuaalization from BIOS

Started Windows

Shutdown

Enabled ALL Virtualization options

Started Windows.

Thanks,

Prabhat

Good deal!

Thanks for marking this solved, and especially for adding useful information.

That's what the poster did in that thread I linked - and why the fix found its way back to you,
