[Gate-users] Re : vGate 1.0 on VirtualBox with two processors

[Marcin Balcerzyk]

Dear Samuel.

What I meant to do is to run two Gate simulations in vGate at the same time,
I would suppose that this would be divided to two hardware processors.  I
had indeed turned off virtualization in BIOS of HP Invent computer. After
turning it on, and setting VBox to two processors, I see two processors in
Ubuntu system monitor, and it starts significantly faster. 

Thank you very much.

Hi,


you should check your hardware visualization capabilities & settings in your
BIOS/EFI and for your specific CPU version.
because multi-cpu visualization do not rely only on software level.

you should also know that multi cpu visualization is really not very
efficient, for GATE we have evaluated :
? 1 virtual CPU ~ 95% efficiency
? 2 virtual CPU ~ 60% efficiency
3-8 virtual CPU ~ 50% efficiency

this do not work the same way than bare-metal visualization !

Objet?: [Gate-users] vGate 1.0 on VirtualBox with two processors

Dear Gaters.



Did anybody managed to start vGate 1.0 with the virtual Ubuntu system set to
work with two processors? I mean the Ubuntu 9 system, not to have
multithread/multiprocessor Gate running. 



I have Windows 7 64 bit with four processors with VirtualBox 4.0.8 and with
one processor in VirtualBox, vGate 1 (Ubuntu, Gate 6 and all simulations)
run fine, but when I set? vGate virtual machine to two processors virtual
machine does not start with error: VERR_VMX_MSR_LOCKED_OR_DISABLED component
console interface console ... etc .



Any suggestions are welcomed.
