[libvirt] virsh vcpuinfo always returns CPU=0
Hi there, I wonder what does the CPU entry stands for in the output of vcpuinfo. I guess it is the CPU utilization rate, right? For both Ubuntu 9.04 (virsh version 0.6.1) and RHEL 5.4 (version 0.6.3), I always get the returned CPU value to be 0, no matter how busy the CPU can be and how many VCPU is used. For example, onnecting to uri: qemu:///system VCPU: 0 CPU: 0 State: running CPU Affinity: yyyyyyyyyyyyyyyy VCPU: 1 CPU: 0 State: running CPU Affinity: yyyyyyyyyyyyyyyy Is this a problem and how do I fix it? Thank you very much. -- Shi Jin, PhD

It is the most recent physical CPU in which the vCPU ran.
