Thanks for quick reply. Above xml is getting generated fine if I set
"vcpu_pin_set=1-12" in /etc/nova/nova.conf.
But how to pin each vcpu with pcpu something like below
<vcpupin vcpu=‘0’ cpuset=‘1-5,12-17’/>
<vcpupin vcpu=‘1’ cpuset=‘2-3,12-17’/>
One more questions is Are Numa nodes are compulsory for pin each vcpu to pcpu?
