vcpuinfo returns a wrong value for kvm with libvirt 0.6.2:
Furthermore even when pinning all - in my case both - vCPUs of the

assigned cpu.
virsh # vcpupin rr019v3 0 1
virsh # vcpuinfo rr019v3
VCPU: 0
CPU: 0

CPU-Affinität: -y
VCPU: 1

Watching at the code in virsh.c i am a little bit on my wits end where
virVcpuInfoPtr is defined as i am no c-programmer - only some java on my
side.
Unfortunately the answer is rather simple. We never fill in any value
for the 'cpu' field of virVcpuInfo for QEMU/KVM guests, which means
the 'CPU:' line should by virsh will always be zero. We need to fix
this in the QEMU driver.
