Re: [Sony-vaio-z-series] A solution to enable VT on vaio z.

2009-08-13 Thread Roberto Lublinerman
Hi, 

I just downloaded the binary BOOTX64.EFI
( http://luna.vmars.tuwien.ac.at/%7Efroemel/insydeh2o_efi/BOOTX64.EFI )
from the site, copied it to an usb drive formatted as FAT32 in the
directory /EFI/BOOT. You don't need to change boot order or anything in
the BIOS. Just insert the stick, boot and you will land in a grub
prompt. The version of grub 2 in the BOOTX64.EFI is already compiled
with the setup_var command.

Best of luck,
Roberto.

 Hi All
 
 Please help
 
 I am having problems getting the VT mod to work for my Z36GD. Where I
 am stuck is I cannot get grub2 to make with the setup_var command. I
 am running Fed 11. I have patched a svn of grub2 and am trying to get
 the ./configure to create a Makefile that includes the setup_var
 command.
 
 I was wondering if you all could give me the command line args or step
 by steps you used to get the VT activated on your systems.
 
 Any help appreciated.
 
 Thanks in advance
 Chris

Hello Ji Yong,

just wanted to quote your pm. answer here..

 The many reports I have seen is that a lot of software knows your CPU
 supports it, but don't check the BIOS.
 The fact that you can run f.i. Virtualbox with 32 bit guest, still
 says nothing about VT.
 If you can run 64 bit guest OS's, that's when you know you have VT
 enabled.
 
 Not sure about that Intel microcode, but it's better (but perhaps not
 safer!) to do the BIOS hack, as that is OS independent.

It just says that your CPU supports VT, but not if it's activated.

 and a working kvm (out of the box) makes me suspect that it does..

KVM even works without VT, but of course only in QEMU mode.

Easiest way to check working VT, is starting Virtualbox. An icon indicates if 
VT is active or not.

On my Z21 the EFI hack was necessary to use VT!

Greets,
Klaus

 Q: is VT not already enabled on sony z-series under Linux completely

 Simple test on cpu flag 'vmx' like:

  # begin test
 echo; echo -n   Full-Virtualization is ;\
 grep '^flags.*vmx' /proc/cpuinfo || echo -n not ;\
 echo suported by your CPU; echo
  # end test

The CPU Flags are only flags, indicates the capabilities available on
the Processor.
To check if that capabilities are enabled you need to check the MSR register.

In Linux you can use the msr-tools package; with the rdmsr utility
you can check the VMX MSR register numbered 0x3A:

$ rdmsr 0x3A
5

That shows bit-2 (0x04) and bit-0 (0x01) of MSR 0x3A are set. bit-2 is
the VT enable bit.



 and a working kvm (out of the box) makes me suspect that it does..

A working virtualization environment does not means that you are using
the processor capabilities to support virtualization.

Try loading the Linux KVM modules

$ sudo modprobe kvm-intel
$ lsmod | grep kvm
kvm_intel  47768  0
kvm   152984  1 kvm_intel

If VT wasn't enabled, there are error reports in /var/log/kern.log  or
/var/log/messages:

kernel:  kvm: disabled by bios



 The report this link [2] is pointing to is speaking about bios. But one
 can eg. completely bypass any bios update by simply installing the
 newest Linux Processor Microcode Data File from Intel [1]:

 sudo apt-get install intel-microcode microcode.ctl

An updated CPU microcode is very useful to correct processor bugs but
it cannot enable a disabled MSR register and cannot add capabilities
not available on the processor.
The BIOS updates correct firmware bugs and not only Processor microcode.


 But even without the newest microcode installed I have got full
 virtualisation support on my VGN-Z21MN (ubuntu-jaunty and -karmic).
 Without any changes to the bios.

 Or did I just misunderstood everything?

Maybe you are using software only virtualization; you can be sure
only checking the VMX MSR register (after checking the CPU Flags).
Hope that this is more clear, anyway ask here anything you don't understand.
