Mine is Fujitsu-Siemens (manufactured by ECS) G31T-M2 which is slightly different from any other which I found on ECS site. So no BIOS there.

It can be also useless -even if dmidecode is right- because the current BIOS revision could be not exposing the VT-x capabilities if they were disabled on purpose by the manufacturer (but can be enabled by updating the BIOS firmware). I think this is one of those specific/complex situations where I prefer to contact the motherboard manufacturer because only they can tell you about the board options and capabilities.

Sure, your BIOS has to provide an option to toggle "on" VT-x, if no, ask the manufacturer for a BIOS update or how to enable this. And as you seem to be running a 64-bits host OS there shouldn't be more tweaks to do. > My system is: > "Linux artifex 3.2.0-3-amd64 #1 SMP Mon Jul 23 02:45:17 UTC 2012 x86_64 > GNU/Linux" > > dmesg: > "[0.051573] CPU0: Intel(R) Core(TM)2 CPU E8400 @ 3.00GHz > stepping 0a > ... > [0.140066] Brought up 2 CPUs > [0.140068] Total of 2 processors activated (11970.46 BogoMIPS)." > > vboxdrv related lines (what and why legacy support warning?): " > [ 55.378467] vboxdrv: Found 2 processor cores. > [ 55.378878] vboxdrv: fAsync=0 offMin=0x22e offMax=0xc57 > [ 55.378926] vboxdrv: TSC mode is 'synchronous', kernel timer mode is > 'normal'. > [ 55.378928] vboxdrv: Successfully loaded version 4.1.18_Debian (interface > 0x0019). > [ 55.452749] vboxpci: IOMMU not found (not registered) > [ 160.448576] warning: `VirtualBox' uses 32-bit capabilities (legacy support > in use)" I think the warning is harmless.

When creating a new Virtual machine, if you select, say, "Debian", you'll get a 32-bit virtual processor. What you need to do is select "Debian (64-bit)", if available, and then your guest can access the 64-bit capabilities. signature.asc Description: Digital signature

So, will 32 bit guests be enough for your use? Thank you. Looks like I have to buy a new CPU with VT. Unfortunately 32 bit is not enough for me as I would like to test 64 bit systems within my Virtualbox. > VT-x/AMD-v cpus are the way to go.

It has higher FSB and clock speed than mine which is a plus. Bye, a -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?

So, will 32 bit guests be enough for your use? VT-x/AMD-v cpus are the way to go. It was a substantial increase in performance when I upgraded.
