[virt-tools-list] [PATCH 1/2] Add a new flag VIR_DOMAIN_CPU_STATS_F_VCPU to virDomainGetCPUStats

Currently virDomainGetCPUStats gets total cpu usage, which consists
of:

  1. vcpu usage: the physical cpu time consumed by virtual cpu(s) of
     domain
  2. hypervisor: `total cpu usage' - `vcpu usage'

The flag VIR_DOMAIN_CPU_STATS_F_VCPU is for getting vcpu usages.
