Hi all,
I want to assign multiple host cores to a VM that are then exposed there as
only one virtual processor core. I want to maximize there the available
computation power and the guest OS cannot handle SMP.
And: How can I enable qemu to run on multiple host cores? I have a i7
HT enabled linux system on another server and don't see that the process is
running on multiple cores but only on one.
Best regards,
Erik

Qemu does not have the ability to aggregate multiple host processors
into a single "super" processor for the guest. When multiple
processors are given to a guest, the guest must support SMP to take
advantage of them. Thanks,
