[Qemu-discuss] cpu threads in nested vm

[Hui Jing]

Hi Guys,

I come across this problem when I deploy nested vm. I found out that the
nested vm is scheduled on a single CPU core in its host (the host here is
the first-level vm), even though it is configured with multiple cores.

here is a simple VM hierarchy diagram:

------  Nested VM     -------
------  First-level VM  ------
------  Host (physical machine)  ------

I have enabled nest feature of intel_kvm module.

I am wondering if it is possible to overcome this issue. Great thanks in
advance.

Best Regards,
Hui
