Description

When illumos is booted with a SMP configuration (multiple cores per socket) on a cloudstack kvm (linux kvm + qemu), it boots with only 1 virtual cpu

An example of such a qemu config
------

<cpu mode='custom' match='exact'>
<model fallback='allow'>Westmere</model>
<topology sockets='1' cores='4' threads='1'/>
</cpu>
------
