Re: [Xen-users] CPUS, cores and threads inside domU
Ah ok I understand better your question. You can indeed assign it several vcpu's since at least version 3.1 which is what I am using. After, these cores will show up as independent CPUs in your VM's.
The config line to add is "vcpus=1" Cheers, Antoine On Mon, Sep 15, 2008 at 11:47 AM, Igor Chubin <igor@xxxxxxx> wrote:

Thank you for you answer, Antoine.
I'm sorry, I think that I had to formulate my question more
precisely.
I do not want give domU any information about real hardware.
I want to provide it with virtual cpus (it is possible, ant question
is not about this) and show this vcpus say as cores of one CPU
or as independent CPUS. AFAIU this become possible since Xen 3.3.
