Hi:
Sometimes the output of kvm_stat is blank and not friendly enough.
This patch is used to fix this problem
Before:
kvm statistics - summary
Event Total %Total CurAvg/s
...
kvm_apic_ipi 1 0.2 5
kvm_emulate_insn 27 4.8
kvm_ioapic_set_irq 9 1.6
kvm_pic_set_irq 9 1.6
kvm_set_irq 9 1.6
Total 30216 1986
After
