--- Comment #4 from liyi <yilikernel@gmail.com>  2012-11-29 15:38:10 ---
1: i have disable the irqbalance in the host, and the irq affinity on the host
is ok.you can see the  4 step in  comment 0.

2: you see in comment 0, we have set irq affinity on the host is pcpu1.
and so reduce the ipi interrupt, so we want to set the irq affinity at the
vcpu2 on the guest os according <vcpupin vcpu='2' cpuset='1'/>, but the irq
affinity on the guest os when using msi-x is failed.
